The `Source` and `Target` dependency properties are of type `Point` and are usually bound to a connector's `Anchor` point.\n\n## Table of contents\n\n- [Base connection](#base-connection)\n- [Line connection](#line-connection)\n- [Circuit connection](#circuit-connection)\n- [Bezier connection](#connection)\n- [Step connection](#step-connection)\n- [Pending connection](#pending-connection)\n- [Custom connection](#custom-connection)\n\n## Using connections\n\nIn the `NodifyEditor`, you can customize both the default connection and the pending connection by assigning a custom `DataTemplate` to the `ConnectionTemplate` and `PendingConnectionTemplate` properties, respectively.\n\n- `ConnectionTemplate`: defines the appearance of established connections between nodes.\n- `PendingConnectionTemplate`: specifies the visual appearance of connections that are in the process of being created (i.e., while the connection is being dragged but not yet completed).\n\nTo customize these, simply set your desired `DataTemplate` on the `NodifyEditor` instance.\n\n## Base connection\n\nThe base class for all connections provided by the library is `BaseConnection` which derives from `Shape`. There's no restriction to derive from `BaseConnection` when you create a custom connection.\n\nIt exposes two commands with their corresponding events:\n\n- `DisconnectCommand`, respectively `DisconnectEvent` - fired when the connection is clicked while holding `ALT`\n- `SplitCommand`, respectively `SplitEvent` - fired when the connection is double-clicked\n\nThe `Direction` of a connection can have two values:\n\n- `Forward`\n\n![image](https://user-images.githubusercontent.com/12727904/192101918-af9b0da6-ecc8-48f7-bf4d-8f9fdd005153.png)\n![image](https://user-images.githubusercontent.com/12727904/192101959-2cb9a837-1642-4e96-b2ef-eea5502a587f.png)\n\n- `Backward`\n\n![image](https://user-images.githubusercontent.com/12727904/192101941-a00e23db-07ae-49ac-a907-72e35ef67877.png)\n![image](https://user-images.githubusercontent.com/12727904/192101977-1afd69f1-dab0-478e-9c3d-7d601486c289.png)\n\nThe `SourceOffset` and the `TargetOffset` work together with `OffsetMode` and will keep a distance from the anchor point:\n\n![image](https://user-images.githubusercontent.com/12727904/192102096-b20887d5-b7ba-450f-9cf3-7fa4086d9637.png)\n\nConnections also have a `Spacing` which will make the connection break the angle at a certain distance from the `Source` and `Target` points:\n\n- With spacing:\n\n![image](https://user-images.githubusercontent.com/12727904/192102286-9a79da8e-5e87-4f60-9e82-979bfabcd6f3.png)\n\n- Without spacing:\n\n![image](https://user-images.githubusercontent.com/12727904/192102302-4125b44a-dfad-4d9e-9131-efb7c17cefbe.png)\n\nSettings the `ArrowSize` to \"0, 0\" will remove the arrowhead.\n\n## Line connection\n\nA straight line from `Source` to `Target`.\n\n![image](https://user-images.githubusercontent.com/12727904/192115137-d8d2145b-a769-4ee9-b4e0-8a362c94e9e7.png)\n\n## Circuit connection\n\nIt has an `Angle` dependency property to control where it breaks.

If `EnablePreview` is true, the `PreviewTarget` will be updated with the connector or item container under the mouse cursor or `null` if there's no such element.\n\n![image](https://user-images.githubusercontent.com/12727904/192115698-fbe29101-884f-4cec-9c25-e318701d30b1.png)\n\nThe visibility of pending connections can be controlled using the `IsVisible` dependency property.\n\nConnection snapping to connectors can be enabled using the `EnableSnapping` dependency property.\n\nThe `Source` and the `Target` properties are data contexts of connectors and the `Target` will be updated when the pending connection is completed.\n\nThere's also a `StartedCommand` which takes the `Source` as the parameter, respectively a `CompletedCommand` which takes the `Target` as the parameter.\n\n> [!TIP]\n> Canceling a pending connection is done by releasing the right mouse button.\n\n## Custom connection\n\nIn some cases, the built-in connections may not provide all the features you need, or your application may need to display hundreds of connections simultaneously. While the built-in connections are feature-rich, they may introduce some overhead that could impact performance. In such cases, you can implement a custom connection to better suit your needs.\n\nThere are several ways to implement a custom connection:\n\n- Derive from one of the existing connection classes and override the appropriate methods.\n- Create a custom control or user control that wraps a built-in connection.\n- Implement a custom connection from scratch.\n\n**Considerations for Implementing a Custom Connection from Scratch**\n\n- The cutting line feature requires the connection type to be added to the `NodifyEditor.CuttingConnectionTypes` collection (see [Cuttline Line - Custom Connections](CuttingLine-Overview#custom-connections))\n- For selection functionality, you must set the `nodify:BaseConnection.IsSelectable` attached property to `true` on the root element.\n- To control the selection state, bind to the `nodify:BaseConnection.IsSelected` attached property on the root element.\n\nExample:\n\n```xml\n<Line X1=\"{Binding Source.Anchor.X}\"\n      X2=\"{Binding Target.Anchor.X}\"\n      Y1=\"{Binding Source.Anchor.Y}\"\n      Y2=\"{Binding Target.Anchor.Y}\"\n      StrokeThickness=\"5\"\n      nodify:BaseConnection.IsSelectable=\"True\"\n      nodify:BaseConnection.IsSelected=\"{Binding IsSelected}\">\n    <Line.Style>\n        <Style TargetType=\"Line\">\n            <Setter Property=\"Stroke\"\n                    Value=\"Red\" />\n            <Style.Triggers>\n                <Trigger Property=\"nodify:BaseConnection.IsSelected\"\n                         Value=\"True\">\n                    <Setter Property=\"Stroke\"\n                            Value=\"Green\" />\n                </Trigger>\n                <Trigger Property=\"nodify:BaseConnection.IsSelectable\"\n                         Value=\"True\">\n                    <Setter Property=\"Cursor\"\n                            Value=\"Hand\" />\n                </Trigger>\n            </Style.Triggers>\n        </Style>\n    </Line.Style>\n</Line>\n```\n"

Connectors have an `Anchor` dependency property that **must** be bound in order to be able to create connections between them that are updated in real-time when the node's position changes. The `IsConnected` dependency property **must** be set to true in order to receive `Anchor` updates.\n\nALT+Click on a connector fires the `DisconnectCommand`.\n\n## NodeInput and NodeOutput\n\nNode input and node output are implementations of `Connector` with a `Header` that can be used to display text or input boxes by customizing the `HeaderTemplate`. They also expose a `ConnectorTemplate` to customize the connector itself. They are usually used in conjunction with `Node.InputConnectorTemplate` and `Node.OutputConnectorTemplate`.\n\n![image](https://user-images.githubusercontent.com/12727904/192117525-a7e1b309-70d6-4ed7-bcd7-8210dbd680ce.png)\n\n"

Otherwise, the items contained in the `SelectedArea` will only be selected after the selection operation is finished.\n\nWhen an `ItemContainer` is selected, its `IsSelected` dependency property is set to `true`.\n\nDifferent behavior is used depending on the `ModifierKeys` held when starting a selection:\n\n- `Replace` - no modifier key (default behavior, clears the selected items and starts a new selection)\n- `Append` - shift key (adds selection to the currently selected items)\n- `Remove` - alt key (removes selection from the currently selected items)\n- `Invert` - control key (removes selected items and adds unselected items)\n\nSelecting items can also be used in combination with panning and zooming.\n\nDefault values:\n\n- `EnableRealtimeSelection`: true\n\n### Selection API\n\nThe following methods can be called on a NodifyEditor instance.\n\n- SelectAll\n- UnselectAll\n- SelectArea\n- InvertSelection\n- UnselectArea\n- SelectAllConnections\n- UnselectAllConnections\n\n## Snapping\n\nWhen a selection is moved the `GridCellSize` dependency property will be used to determine where to snap the selected items.\nThe snapping is relative to the position of the selected item and not the virtual grid.\n\nIf the selected items are not snapped to the grid when they are initially created or if the `GridCellSize` is changed at runtime, the final position will be corrected after moving the selection if the `EnableSnappingCorrection` dependency property is `true`.\n\nDefault values:\n\n- `GridCellSize`: 1\n- `EnableSnappingCorrection`: true\n\n## Pushing Items\n\nThe Pushing Items feature allows users to interactively move items within the editor by performing a drag gesture.\n\nTo initiate the push operation, hold `CTRL+SHIFT` and click with the **Left Mouse Button**. During the push items operation, the `IsPushingItems` dependency property is set to `true`, the `PushOrientation` dependency property is initialized with the direction the user is dragging, and the `PushedArea` dependency property updates in real time to reflect the interaction state.\n\nTo cancel the push operation, press the `Escape` key or release `CTRL+SHIFT` and click the **Right Mouse Button**. You can configure the default keybindings by modifying the `EditorGestures.Editor.PushItems` gesture. To prevent cancellation, set `NodifyEditor.AllowPushItemsCancellation` to `false`.\n\nThe visual appearance of the push area can be customized by setting the `PushedAreaStyle` property.\n\n## Commands\n\nThe following `RoutedUICommand`s are found in the `EditorCommands` class:\n\n- `ZoomIn` - `CTRL +` (zoom in relative to the viewport's center)\n- `ZoomOut` - `CTRL -` (zoom out relative to the viewport's center)\n- `SelectAll` - `CTRL A` (select all items)\n- `BringIntoView` - Moves the viewport to the specified location, defaults to [0,0]. (`CommandParameter` is the location of type `Point` or `string`)\n- `Align` - Aligns the selected items using the specified alignment method, defaults to Top. (`CommandParameter` is of type `Alignment` or `string`. Possible alignment: Top, Left, Bottom, Right, Middle, Center)\n- `FitToScreen` - Scales and moves the `Viewport` to display as many items as possible\n\n## Editor API\n\nYou can programmatically call the corresponding methods of these commands on an instance of a `NodifyEditor`.\n\n- FitToScreen\n- BringIntoView\n- ZoomAtPosition\n- ZoomIn\n- ZoomOut\n"

    "content": "It is _important_ to understand how components are named and what's their role in the visual tree of the editor to understand the code and the documentation.\n\n## Hierarchy and terminology\n\nThe root component is an [editor](Editor-Overview) which holds [nodes](Nodes-Overview) and [connections](Connections-Overview) together with a few additional UI elements such as a [selection rectangle](Editor-Overview#selecting) and a [pending connection](Connections-Overview#pending-connection) in order to make the editor interactive.\n\nNodes are containers for [connectors](Connectors-Overview) or the node itself can be a connector (e.g. [State Node](Nodes-Overview#4-the-statenode-control)).\n\nConnectors can create pending connections that can become real connections when completed.\n\n_A picture is worth a thousand words_\n\n![nodes-hierarchy](https://user-images.githubusercontent.com/12727904/192028123-e2847f29-6517-4731-8672-f5d8356dead0.png)\n\n## Content Layers\n\nYou may wonder how a node can be a connector itself and still behave like a normal node. The editor contains three big layers which help solve this problem:\n\n1. The items layer (`NodifyEditor.ItemsSource`) - here, each control is wrapped inside an [Item Container](ItemContainer-Overview) making it selectable, draggable, etc and it is possible to have any control rendered (e.g a connector, a text block).\n2. The connections layer (`NodifyEditor.Connections`) - this is where all the [connections](Connections-Overview) coexist and are rendered behind the items layer by default\n3. The decorators layer (`NodifyEditor.Decorators`) - here, each control is given a location inside the graph\n\nHaving those layers separated enables the possibility of asynchronously loading each one of them.\n\n## Using an existing theme\n\nMerge one of the following themes into your resource dictionary in `App.xaml`:\n\n- Dark theme (default theme if not specified):\n\n```xml\n<ResourceDictionary Source=\"pack://application:,,,/Nodify;component/Themes/Dark.xaml\" />\n```\n\n- Light theme:\n\n```xml\n<ResourceDictionary Source=\"pack://application:,,,/Nodify;component/Themes/Light.xaml\" />\n```\n\n- Nodify theme:\n\n```xml\n<ResourceDictionary Source=\"pack://application:,,,/Nodify;component/Themes/Nodify.xaml\" />\n```\n\n## A minimal example\n\nImport the `nodify` namespace: `xmlns:nodify=\"https://miroiu.github.io/nodify\"` or `xmlns:nodify=\"clr-namespace:Nodify;assembly=Nodify\"` in your file and create an instance of the editor `<nodify:NodifyEditor />`. If you start the application, you will see an empty space where you can create a selection rectangle.\n\n> Tip: Drag the selection rectangle near the edge of the editor area and the screen will automatically move in that direction.\n\n### Adding nodes\n\nNow we're going to display a few nodes. Let's create the viewmodels and bind them to the view.\n\n```csharp\npublic class NodeViewModel\n{\n    public string Title { get; set; }\n}\n\npublic class EditorViewModel\n{\n    public ObservableCollection<NodeViewModel> Nodes { get; } = new ObservableCollection<NodeViewModel>();\n\n    public EditorViewModel()\n    {\n        Nodes.Add(new NodeViewModel { Title = \"Welcome\" });\n    }\n}\n```\n\nThe view model can be of any shape, but the view for the node is generated by the `ItemTemplate`. (The same result would be achieved by having the DataTemplate inside NodifyEditor.Resources)\n\n```xml\n<nodify:NodifyEditor ItemsSource=\"{Binding Nodes}\">\n    <nodify:NodifyEditor.DataContext>\n        <local:EditorViewModel />\n    </nodify:NodifyEditor.DataContext>\n\n    <nodify:NodifyEditor.ItemTemplate>\n        <DataTemplate DataType=\"{x:Type local:NodeViewModel}\">\n            <nodify:Node Header=\"{Binding Title}\" />\n        </DataTemplate>\n    </nodify:NodifyEditor.ItemTemplate>\n\n</nodify:NodifyEditor>\n```\n\nNotice how we bind the `Header` of the `Node` to display the `Title`. For more node types and customization please check out the [Nodes overview](Nodes-Overview).\n\n### Connecting nodes\n\nAlright, now let's add more nodes and connect them together. First, we need a representation of a connector and some collections on the node to store our connectors.\n\n```csharp\npublic class ConnectorViewModel\n{\n    public string Title { get; set; }\n}\n\npublic class NodeViewModel\n{\n    public string Title { get; set; }\n\n    public ObservableCollection<ConnectorViewModel> Input { get; set; } = new ObservableCollection<ConnectorViewModel>();\n    public ObservableCollection<ConnectorViewModel> Output { get; set; } = new ObservableCollection<ConnectorViewModel>();\n}\n\npublic class EditorViewModel\n{\n    public ObservableCollection<NodeViewModel> Nodes { get; } = new ObservableCollection<NodeViewModel>();\n\n    public EditorViewModel()\n    {\n        Nodes.Add(new NodeViewModel\n        {\n            Title = \"Welcome\",\n            Input = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"In\"\n                }\n            },\n            Output = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"Out\"\n                }\n            }\n        });\n    }\n}\n```\n\nAnd bind them to the view. (We used the built-in `NodeInput` and `NodeOutput` for the view, but there are [other connectors](Connectors-Overview) too. Or you can create your own, depending on your needs.)\n\n```xml\n<nodify:Node Header=\"{Binding Title}\"\n             Input=\"{Binding Input}\"\n             Output=\"{Binding Output}\">\n  <nodify:Node.InputConnectorTemplate>\n      <DataTemplate DataType=\"{x:Type local:ConnectorViewModel}\">\n          <nodify:NodeInput Header=\"{Binding Title}\" />\n      </DataTemplate>\n  </nodify:Node.InputConnectorTemplate>\n\n  <nodify:Node.OutputConnectorTemplate>\n      <DataTemplate DataType=\"{x:Type local:ConnectorViewModel}\">\n          <nodify:NodeOutput Header=\"{Binding Title}\" />\n      </DataTemplate>\n  </nodify:Node.OutputConnectorTemplate>\n</nodify:Node>\n```\n\nThe `Node` control supports `Input` and `Output` connectors and the way you customize these is by overwriting the default template for the `InputConnectorTemplate`, respectively the `OutputConnectorTemplate`.\n\nClicking and dragging a wire from the `Input` or `Output` connector will create a [pending connection](Connections-Overview#pending-connection) that we can transform into a real connection.\n\n**The most complicated part of Nodify is how you bind the connections to their connectors.** Let's create the ViewModel for the connection and add a list of connections in the `EditorViewModel`.\n\n```csharp\npublic class ConnectionViewModel\n{\n    public ConnectorViewModel Source { get; set; }\n    public ConnectorViewModel Target { get; set; }\n}\n\npublic class EditorViewModel\n{\n    public ObservableCollection<NodeViewModel> Nodes { get; } = new ObservableCollection<NodeViewModel>();\n    public ObservableCollection<ConnectionViewModel> Connections { get; } = new ObservableCollection<ConnectionViewModel>();\n\n    public EditorViewModel()\n    {\n        var welcome = new NodeViewModel\n        {\n            Title = \"Welcome\",\n            Input = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"In\"\n                }\n            },\n            Output = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"Out\"\n                }\n            }\n        };\n\n        var nodify = new NodeViewModel\n        {\n            Title = \"To Nodify\",\n            Input = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"In\"\n                }\n            }\n        };\n\n        Nodes.Add(welcome);\n        Nodes.Add(nodify);\n\n        Connections.Add(new ConnectionViewModel\n        {\n            Source = welcome.Output[0],\n            Target = nodify.Input[0]\n        });\n    }\n}\n```\n\nThen update the `ConnectorViewModel` to have an `Anchor` point that the connection can attach to. (This needs to be reactive, so we're gonna implement INotifyPropertyChanged in the view model).\n\n> Note: The `Point` type must be from System.Windows.\n\n```csharp\npublic class ConnectorViewModel : INotifyPropertyChanged\n{\n    private Point _anchor;\n    public Point Anchor\n    {\n        set\n        {\n            _anchor = value;\n            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Anchor)));\n        }\n        get => _anchor;\n    }\n\n    public string Title { get; set; }\n\n    public event PropertyChangedEventHandler PropertyChanged;\n}\n```\n\nBind the `Anchor` to the connector's view as `Mode=OneWayToSource`. And also set the `IsConnected` to `True` to receive `Anchor` updates.\n\n```xml\n<nodify:Node.InputConnectorTemplate>\n    <DataTemplate DataType=\"{x:Type local:ConnectorViewModel}\">\n        <nodify:NodeInput Header=\"{Binding Title}\"\n                          IsConnected=\"True\"\n                          Anchor=\"{Binding Anchor, Mode=OneWayToSource}\" />\n    </DataTemplate>\n</nodify:Node.InputConnectorTemplate>\n\n<nodify:Node.OutputConnectorTemplate>\n    <DataTemplate DataType=\"{x:Type local:ConnectorViewModel}\">\n        <nodify:NodeOutput Header=\"{Binding Title}\"\n                           IsConnected=\"True\"\n                           Anchor=\"{Binding Anchor, Mode=OneWayToSource}\"  />\n    </DataTemplate>\n</nodify:Node.OutputConnectorTemplate>\n```\n\nAnd bind the connections to the view and let them use our `ConnectorViewModel`'s `Anchor` in the `ConnectionTemplate`. For more customization, please refer to [connections overview](Connections-Overview).\n\n```xml\n<nodify:NodifyEditor ItemsSource=\"{Binding Nodes}\"\n                     Connections=\"{Binding Connections}\">\n    ...\n    <nodify:NodifyEditor.ConnectionTemplate>\n        <DataTemplate DataType=\"{x:Type local:ConnectionViewModel}\">\n            <nodify:LineConnection Source=\"{Binding Source.Anchor}\"\n                                   Target=\"{Binding Target.Anchor}\" />\n        </DataTemplate>\n    </nodify:NodifyEditor.ConnectionTemplate>\n    ...\n```\n\nIf you start the application now, you'll see that there is a connection and if you drag the nodes around, it will follow them.\n\nNow let's add the `IsConnected` property to the `ConnectorViewModel` so we can set it whenever it is truly connected or not. And update the `ConnectionViewModel` to connect them automatically on construction.\n\n```csharp\npublic class ConnectorViewModel : INotifyPropertyChanged\n{\n    private Point _anchor;\n    public Point Anchor\n    {\n        set\n        {\n            _anchor = value;\n            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Anchor)));\n        }\n        get => _anchor;\n    }\n\n    private bool _isConnected;\n    public bool IsConnected\n    {\n        set\n        {\n            _isConnected = value;\n            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(IsConnected)));\n        }\n        get => _isConnected;\n    }\n\n    public string Title { get; set; }\n\n    public event PropertyChangedEventHandler PropertyChanged;\n}\n\npublic class ConnectionViewModel\n{\n    public ConnectionViewModel(ConnectorViewModel source, ConnectorViewModel target)\n    {\n        Source = source;\n        Target = target;\n\n        Source.IsConnected = true;\n        Target.IsConnected = true;\n    }\n\n    public ConnectorViewModel Source { get; }\n    public ConnectorViewModel Target { get; }\n}\n```\n\nAnd don't forget to bind it in the connector template.\n\n```xml\nIsConnected=\"{Binding IsConnected}\"\n```\n\n### Materializing pending connections\n\nThe [PendingConnection](Connections-Overview#pending-connection) starts from a `Source` and will be completed when dropped on a `Target`. The source is _always_ a connector, and the target can be a [Connector](Connectors-Overview), an [ItemContainer](ItemContainer-Overview) or `null` otherwise. We will only care about other connectors for now. When the connection starts, the `StartedCommand` is executed which receives the `Source` as the parameter. When the connection completes, the `CompletedCommand` is executed which receives the `Target` as the parameter.\n\nTo create the commands we need an implementation of `ICommand`. I will use the following generic implementation:\n\n```csharp\npublic class DelegateCommand<T> : ICommand\n{\n    private readonly Action<T> _action;\n    private readonly Func<T, bool>? _condition;\n\n    public event EventHandler? CanExecuteChanged;\n\n    public DelegateCommand(Action<T> action, Func<T, bool>? executeCondition = default)\n    {\n        _action = action ?? throw new ArgumentNullException(nameof(action));\n        _condition = executeCondition;\n    }\n\n    public bool CanExecute(object? parameter)\n    {\n        if (parameter is T value)\n        {\n            return _condition?.Invoke(value) ?? true;\n        }\n\n        return _condition?.Invoke(default!) ?? true;\n    }\n\n    public void Execute(object? parameter)\n    {\n        if (parameter is T value)\n        {\n            _action(value);\n        }\n        else\n        {\n            _action(default!);\n        }\n    }\n\n    public void RaiseCanExecuteChanged()\n        => CanExecuteChanged?.Invoke(this, new EventArgs());\n}\n```\n\nLet's implement the pending connection view model and add it to the `EditorViewModel`.\n\n```csharp\npublic class PendingConnectionViewModel\n{\n    private readonly EditorViewModel _editor;\n    private ConnectorViewModel _source;\n\n    public PendingConnectionViewModel(EditorViewModel editor)\n    {\n        _editor = editor;\n        StartCommand = new DelegateCommand<ConnectorViewModel>(source => _source = source);\n        FinishCommand = new DelegateCommand<ConnectorViewModel>(target =>\n        {\n            if (target != null)\n                _editor.Connect(_source, target);\n        });\n    }\n\n    public ICommand StartCommand { get; }\n    public ICommand FinishCommand { get; }\n}\n\npublic class EditorViewModel\n{\n    public PendingConnectionViewModel PendingConnection { get; }\n\n    ...\n\n    public EditorViewModel()\n    {\n        PendingConnection = new PendingConnectionViewModel(this);\n        ...\n    }\n\n    ...\n\n    public void Connect(ConnectorViewModel source, ConnectorViewModel target)\n    {\n        Connections.Add(new ConnectionViewModel(source, target));\n    }\n}\n```\n\nAnd bind it to the view.\n\n```xml\n<nodify:NodifyEditor PendingConnection=\"{Binding PendingConnection}\">\n...\n    <nodify:NodifyEditor.PendingConnectionTemplate>\n        <DataTemplate DataType=\"{x:Type local:PendingConnectionViewModel}\">\n            <nodify:PendingConnection StartedCommand=\"{Binding StartCommand}\"\n                                      CompletedCommand=\"{Binding FinishCommand}\"\n                                      AllowOnlyConnectors=\"True\" />\n        </DataTemplate>\n    </nodify:NodifyEditor.PendingConnectionTemplate>\n...\n</nodify:NodifyEditor>\n```\n\nThat's all. You should be able to create connections between connectors now.\n\n### Removing connections\n\nTo remove connections you just have to listen for a disconnect event from the connector itself or from the editor and remove the connection that has the connector as the source or target. To keep it simple, we're gonna implement the `DisconnectConnectorCommand` for the `NodifyEditor`. Let's add it to the `EditorViewModel` first.\n\n```csharp\npublic class EditorViewModel\n{\n    public ICommand DisconnectConnectorCommand { get; }\n\n    ...\n\n    public EditorViewModel()\n    {\n        DisconnectConnectorCommand = new DelegateCommand<ConnectorViewModel>(connector =>\n        {\n            var connection = Connections.First(x => x.Source == connector || x.Target == connector);\n            connection.Source.IsConnected = false;  // This is not correct if there are multiple connections to the same connector\n            connection.Target.IsConnected = false;\n            Connections.Remove(connection);\n        });\n\n        ...\n    }\n}\n```\n\nNow we have to bind the command to the editor view.\n\n```xml\n<nodify:NodifyEditor ItemsSource=\"{Binding Nodes}\"\n                     Connections=\"{Binding Connections}\"\n                     PendingConnection=\"{Binding PendingConnection}\"\n                     DisconnectConnectorCommand=\"{Binding DisconnectConnectorCommand}\">\n  ...\n\n</nodify:NodifyEditor>\n```\n\n### Controlling node location\n\nAs you can see, the nodes are always in the top left corner of the screen. That's because they are at location (0, 0) inside the graph. Let's change that!\n\nAdd a `Location` property of type `System.Windows.Point` in the `NodeViewModel` that raises PropertyChanged events.\n\n```csharp\npublic class NodeViewModel : INotifyPropertyChanged\n{\n    private Point _location;\n    public Point Location\n    {\n        set\n        {\n            _location = value;\n            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Location)));\n        }\n        get => _location;\n    }\n\n    public event PropertyChangedEventHandler PropertyChanged;\n\n    ...\n}\n```\n\nAnd bind it to the view.\n\n```xml\n<nodify:NodifyEditor ItemsSource=\"{Binding Nodes}\"\n                     Connections=\"{Binding Connections}\"\n                     PendingConnection=\"{Binding PendingConnection}\">\n\n    <nodify:NodifyEditor.ItemContainerStyle>\n        <Style TargetType=\"{x:Type nodify:ItemContainer}\">\n            <Setter Property=\"Location\"\n                    Value=\"{Binding Location}\" />\n        </Style>\n    </nodify:NodifyEditor.ItemContainerStyle>\n\n    ...\n\n</nodify:NodifyEditor>\n```\n\n> Note: I used the `ItemContainerStyle` to bind the location of the node. Please check out the [ItemContainer overview](ItemContainer-Overview) for more info.\n\nNow you can set the location of the nodes when constructed.\n\n## Drawing a grid\n\nDrawing a simple grid is just a matter of creating a grid brush, applying the editor transform to it, and using the brush as the `Background` of the editor.\n\nBecause the grid we are drawing is made of lines and is not filled, the `Background` of the editor will have some transparency, meaning that we'll see the background color of the control below. To solve this, wrap the editor in a `Grid` and set its `Background` or set the `Background` of the `Window`.\n\nUse the `ViewportTransform` dependency property to have the grid move with the view.\n\n> Note: The example uses static resources which are provided by the selected theme in `App.xaml`.\n\n```xml\n<Window x:Class=\"MyProject.MainWindow\"\n        xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"\n        xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"\n        xmlns:d=\"http://schemas.microsoft.com/expression/blend/2008\"\n        xmlns:mc=\"http://schemas.openxmlformats.org/markup-compatibility/2006\"\n        xmlns:nodify=\"https://miroiu.github.io/nodify\"\n        mc:Ignorable=\"d\">\n\n    <Window.Resources>\n        <GeometryDrawing x:Key=\"SmallGridGeometry\"\n                        Geometry=\"M0,0 L0,1 0.03,1 0.03,0.03 1,0.03 1,0 Z\"\n                        Brush=\"{StaticResource NodifyEditor.SelectionRectangleBackgroundBrush}\" />\n\n        <GeometryDrawing x:Key=\"LargeGridGeometry\"\n                        Geometry=\"M0,0 L0,1 0.015,1 0.015,0.015 1,0.015 1,0 Z\"\n                        Brush=\"{StaticResource NodifyEditor.SelectionRectangleBackgroundBrush}\" />\n\n        <DrawingBrush x:Key=\"SmallGridLinesDrawingBrush\"\n                    TileMode=\"Tile\"\n                    ViewportUnits=\"Absolute\"\n                    Viewport=\"0 0 20 20\"\n                    Transform=\"{Binding ViewportTransform, ElementName=Editor}\"\n                    Drawing=\"{StaticResource SmallGridGeometry}\" />\n\n        <DrawingBrush x:Key=\"LargeGridLinesDrawingBrush\"\n                    TileMode=\"Tile\"\n                    ViewportUnits=\"Absolute\"\n                    Opacity=\"0.5\"\n                    Viewport=\"0 0 100 100\"\n                    Transform=\"{Binding ViewportTransform, ElementName=Editor}\"\n                    Drawing=\"{StaticResource LargeGridGeometry}\" />\n    </Window.Resources>\n\n    <Grid Background=\"{StaticResource NodifyEditor.BackgroundBrush}\">\n        <nodify:NodifyEditor x:Name=\"Editor\" Background=\"{StaticResource SmallGridLinesDrawingBrush}\" />\n\n        <Grid Background=\"{StaticResource LargeGridLinesDrawingBrush}\"\n              Panel.ZIndex=\"-2\" />\n    </Grid>\n</Window>\n```\n\n> Tip: Right-click and drag the screen around to move the view and use the mouse wheel to zoom in and out.\n"

Unlike Blueprints, Nodify is a general-purpose library that offers a node graph editor component that can be embedded in any WPF application.\n\nThe graph editor is an infinite area where you can place and move nodes around, select and drag groups of nodes, connect and disconnect nodes or connectors, zoom in and out, and automatically move the screen when dragging a node or a wire near the edges and much more.\n\nNodify is feature-rich and optimized for interaction with hundreds of nodes at once, and... it is built from the ground up to work with MVVM.\n\n### Requirements\n\n![IDE](https://img.shields.io/static/v1?label=%20&message=VS%202019%20or%20greater&color=informational&style=for-the-badge&logo=visual-studio)\n![C#](https://img.shields.io/static/v1?label=%20&message=8.0&color=239120&style=for-the-badge&logo=c-sharp)\n![.NET](https://img.shields.io/static/v1?label=%20&message=Framework%204.7.2%20to%20NET%206&color=5C2D91&style=for-the-badge&logo=.net)\n\n### Install Nodify from Nuget\n\n[![Download Package](https://img.shields.io/nuget/v/Nodify?label=Download&logo=nuget&style=for-the-badge)](https://www.nuget.org/packages/Nodify/)\n\n```xml\nInstall-Package Nodify\n```\n\n### Application examples\n\n- [Playground](https://github.com/miroiu/nodify/tree/master/Examples/Nodify.Playground)\n- [Shapes](https://github.com/miroiu/nodify/tree/master/Examples/Nodify.Shapes)\n- [State machine](https://github.com/miroiu/nodify/tree/master/Examples/Nodify.StateMachine)\n- [Calculator](https://github.com/miroiu/nodify/tree/master/Examples/Nodify.Calculator)\n\n[![IDE](https://img.shields.io/static/v1?label=%20&message=GET%20STARTED&color=9cf&style=for-the-badge)](Getting-Started)\n"

It inherits from `ItemsControl` and displays items through the `ItemsSource` property. Each item is wrapped in a `MinimapItem` container that requires the `Location`, `Width`, and `Height` properties to be set in the `ItemContainerStyle`.\n\n> [!TIP]\n> For real-time movement of nodes inside the minimap, it's required to set `NodifyEditor.EnableDraggingContainersOptimizations` to `false`.\n\nThe control also displays a viewport rectangle that represents the visible area in the editor and requires the `ViewportLocation` and `ViewportSize` properties to be set.\n\n```xml\n<nodify:Minimap\n    ItemsSource=\"{Binding ItemsSource, ElementName=Editor}\"\n    ViewportLocation=\"{Binding ViewportLocation, ElementName=Editor}\"\n    ViewportSize=\"{Binding ViewportSize, ElementName=Editor}\"\n    Zoom=\"OnMinimapZoom\">\n    <nodify:Minimap.ItemContainerStyle>\n        <Style TargetType=\"nodify:MinimapItem\">\n            <Setter Property=\"Location\" Value=\"{Binding MyItemLocation}\" />\n        </Style>\n    </nodify:Minimap.ItemContainerStyle>\n</nodify:Minimap>\n```\n\n```csharp\nprivate void OnMinimapZoom(object sender, ZoomEventArgs e)\n{\n    Editor.ZoomAtPosition(e.Zoom, e.Location);\n}\n```\n\n> [!IMPORTANT]\n> The `Width` and `Height` should be constrained by the parent container or set to constant values on the `Minimap` to prevent resizing to fit the content.\n\n## Panning\n\nPanning is done by holding click and dragging and can be disabled by setting the `IsReadOnly` property to `true`. The `ViewportLocation` is updated during panning, therefore it must be a two-way binding (binds two ways by default).\n\nThe panning gesture can be configured by setting `EditorGestures.Mappings.Minimap.DragViewport` to the desired gesture.\n\n## Zooming\n\nZooming is done by scrolling the mouse wheel and can be disabled by setting the `IsReadOnly` property to `true` or by not handling the `Zoom` event.\n\nThe zooming modifier key can be configured by setting `EditorGestures.Mappings.Minimap.ZoomModifierKey` to the desired value.\n\n## Customization\n\nThe `ViewportStyle` is used to customize the viewport rectangle.\n\n```xml\n<Style x:Key=\"MyViewportStyle\" TargetType=\"Rectangle\">\n    <Setter Property=\"Fill\" Value=\"Transparent\"/>\n    <Setter Property=\"Stroke\" Value=\"White\"/>\n    <Setter Property=\"StrokeThickness\" Value=\"3\"/>\n</Style>\n\n<nodify:Minimap ViewportStyle=\"{StaticResource MyViewportStyle}\" ... />\n```\n\nThe `MaxViewportOffset` property is used to restrict how far the viewport can be moved away from the items when [panning](#panning).\n\nThe `ResizeToViewport` property changes the resizing behavior of the minimap.\nIf `true`, the minimap will resize to always display the viewport alongside the items.\n\n![scale-with-viewport](https://github.com/user-attachments/assets/7a8887bf-f3f4-44d7-8311-6d9ba7869d78)\n\nIf `false`, the minimap will resize to only include the items, allowing the viewport to go out of bounds.\n\n![viewport-out-of-bounds](https://github.com/user-attachments/assets/5d3b388e-8e40-4bfe-af3b-4c12fb47548d)\n"

    "content": "Nodes are the building blocks of a node editor. They are wrapped in [`ItemContainer`s](ItemContainer-Overview) and can be any custom control. (e.g. a TextBlock)\n\nThe following nodes are part of the library:\n\n### 1. The ```Node``` control\nThis type of node supports both ```Input``` and ```Output``` connectors and can be moved around.\n\n```xml\n<nodify:NodifyEditor xmlns:sys=\"clr-namespace:System;assembly=mscorlib\">\n  <nodify:NodifyEditor.ItemsSource>\n    <CompositeCollection>\n        <nodify:Node Header=\"My Node\">\n            <nodify:Node.Input>\n                <CompositeCollection>\n                    <sys:String>In 0</sys:String>\n                    <sys:String>In 1</sys:String>\n                </CompositeCollection>\n            </nodify:Node.Input>\n            <nodify:Node.Output>\n                <CompositeCollection>\n                    <sys:String>Out 0</sys:String>\n                    <sys:String>Out 1</sys:String>\n                </CompositeCollection>\n            </nodify:Node.Output>\n            <nodify:Node.InputConnectorTemplate>\n                <DataTemplate>\n                    <nodify:NodeInput Header=\"{Binding}\" />\n                </DataTemplate>\n            </nodify:Node.InputConnectorTemplate>\n            <nodify:Node.OutputConnectorTemplate>\n                <DataTemplate>\n                    <nodify:NodeOutput Header=\"{Binding}\" />\n                </DataTemplate>\n            </nodify:Node.OutputConnectorTemplate>\n        </nodify:Node>\n    </CompositeCollection>\n  </nodify:NodifyEditor.ItemsSource>\n</nodify:NodifyEditor>\n```\n\nThe `Header` of the node can be customized using the `HeaderTemplate`. Respectively, the `Footer` of the node can be customized using the `FooterTemplate`.\n\nEach item in the `Input` collection can be customized using the `InputConnectorTemplate`. Respectively the `Output` can be customized using the `OutputConnectorTemplate`.\n\n![Node](https://i.imgur.com/VwAYlX3.gif)\n\n### 2. The ```GroupingNode``` control\n\nThis type of node can be resized and will move nodes that are inside it if dragged by the ```Header```.\n\nIf the ```SwitchMovementModeModifierKey``` (**Shift** key by default) is held, it will move without moving its children.\n\n```xml\n<nodify:NodifyEditor>\n    <nodify:NodifyEditor.ItemsSource>\n        <CompositeCollection>\n            <nodify:GroupingNode Header=\"Grouping node\"\n                            Width=\"300\"\n                            Height=\"250\" />            \n            <nodify:Node Header=\"My node\" />\n            <nodify:Node Header=\"My other node\" />\n        </CompositeCollection>\n    </nodify:NodifyEditor.ItemsSource>\n</nodify:NodifyEditor>\n```\n\nThe `Header` of the node can be customized using the `HeaderTemplate`. Respectively the `Content` of the node can be customized using the `ContentTemplate`.\n\nThe size of the node can be set programmatically by changing the `ActualSize` dependency property value. \n\n#### Default values\n\n* CanResize: true\n* MovementMode: Grouped\n\n#### Commands\n\n* ResizeCompleted\n* ResizeStarted\n\n![Grouping Node](https://i.imgur.com/HYxt2cs.gif)\n\n### 3. The ```KnotNode``` control\n\nThis type of control can be used to reroute ```Connection```s as it supports only one ```Connector```. \n\nThe `Content` of the node can be customized using the `ContentTemplate`. \n\n```xml\n<nodify:NodifyEditor>\n    <nodify:NodifyEditor.ItemsSource>\n        <CompositeCollection>\n            <nodify:KnotNode />\n        </CompositeCollection>\n    </nodify:NodifyEditor.ItemsSource>\n</nodify:NodifyEditor>\n```\n\n![Knot Node](https://i.imgur.com/fMrEqY1.gif)\n\n### 4. The ```StateNode``` control\n\nThis type of node is a ```Connector``` itself, meaning that it will raise ```PendingConnection``` events on interaction. Because it inherits from `Connector`, you need to bind the `Anchor` property and `IsConnected` to the corresponding state. (if IsConnected is set to false, the connections won't update)\n\n```xml\n<nodify:NodifyEditor>\n    <nodify:NodifyEditor.ItemsSource>\n        <CompositeCollection>\n            <nodify:StateNode Content=\"My node\" />\n        </CompositeCollection>\n    </nodify:NodifyEditor.ItemsSource>\n</nodify:NodifyEditor>\n```\n\nThe `Content` of the node can be customized using the `ContentTemplate`.\n\n![State Node](https://i.imgur.com/FrI2epL.gif)"

    "content": "了解组件的命名方式及其在编辑器可视化树中的角色对于理解代码和文档非常重要。\n\n## 层次结构和术语\n\n根组件是一个[编辑器（editor）](编辑器概述)，它包含[节点（nodes）](节点概述)和[连接（connections）](连接概述)以及一些额外的UI元素，如[选择框（selection rectangle）](编辑器概述#选择)和一个[预备连接（pending connection）](连接概述#预备连接)，以使编辑器具有交互性。\n\n节点是[连接器(connectors)](连接器概述)的容器，有时候节点本身也可以作为连接器(比如 [状态节点](节点概述#4-状态节点(state-node)控件)).\n\n连接器可以创建预备连接，预备连接在完成后可以成为实际的连接。\n\n_一图胜千言_\n\n![nodes-hierarchy](https://user-images.githubusercontent.com/12727904/192028123-e2847f29-6517-4731-8672-f5d8356dead0.png)\n\n## 内容层\n\n你可能会好奇，一个节点如何既能作为连接器本身又能像普通节点一样运行。编辑器包含三个主要层次，这些层次有助于解决这个问题：\n\n1. 项目层（NodifyEditor.ItemsSource）——在这里，每个控件都被包装在一个容器中，使其可以选择、拖动等，并且可以渲染任何控件（例如连接器、文本块）\n2. 连接层（NodifyEditor.Connections）——这是所有连接共存的地方，并默认在项目层下面渲染。\n3. 装饰层（NodifyEditor.Decorators）——在这里，每个控件在窗口中都有一个位置。\n\n将这些层次分开，使得每个层次可以异步加载成为可能。\n\n## 使用现有主题\n\n将以下其中一个主题合并到 App.xaml 中的资源字典中：\n\n- 深色主题（如果未指定，则为默认主题）：\n```xml\n<ResourceDictionary Source=\"pack://application:,,,/Nodify;component/Themes/Dark.xaml\" />\n```\n\n- 浅色主题：\n```xml\n<ResourceDictionary Source=\"pack://application:,,,/Nodify;component/Themes/Light.xaml\" />\n```\n\n- Nodify主题：\n```xml\n<ResourceDictionary Source=\"pack://application:,,,/Nodify;component/Themes/Nodify.xaml\" />\n```\n\n## 一个小案例\n\n导入 `nodify` 命名空间：`xmlns:nodify=\"https://miroiu.github.io/nodify\"` 或 `xmlns:nodify=\"clr-namespace:Nodify;assembly=Nodify\"` 到你的文件中，并创建一个编辑器实例 `<nodify:NodifyEditor />`。如果你启动应用程序，你会看到一个可以创建选择矩形的空白区域。\n> 提示：将选择矩形拖动到编辑器区域的边缘附近，屏幕将自动向该方向移动。\n\n### 添加节点（nodes）\n\n现在我们将显示一些节点。让我们创建视图模型并将它们绑定到视图。\n\n```csharp\npublic class NodeViewModel\n{\n    public string Title { get; set; }\n}\n\npublic class EditorViewModel\n{\n    public ObservableCollection<NodeViewModel> Nodes { get; } = new ObservableCollection<NodeViewModel>();\n\n    public EditorViewModel()\n    {\n        Nodes.Add(new NodeViewModel { Title = \"Welcome\" });\n    }\n}\n```\n\n视图模型可以是任何形状，但节点的视图由 `ItemTemplate` 生成。（将 DataTemplate 放在 NodifyEditor.Resources 中也能实现相同的效果）\n\n```xml\n<nodify:NodifyEditor ItemsSource=\"{Binding Nodes}\">\n    <nodify:NodifyEditor.DataContext>\n        <local:EditorViewModel />\n    </nodify:NodifyEditor.DataContext>\n\n    <nodify:NodifyEditor.ItemTemplate>\n        <DataTemplate DataType=\"{x:Type local:NodeViewModel}\">\n            <nodify:Node Header=\"{Binding Title}\" />\n        </DataTemplate>\n    </nodify:NodifyEditor.ItemTemplate>\n    \n</nodify:NodifyEditor>\n```\n\n请注意，我们绑定 Node 的 Header 属性来显示 Title。要了解更多节点类型和自定义，请查看[节点概述](节点概述)。\n\n### 连接节点（nodes）\n\n好的，现在让我们添加更多节点并将它们连接起来。首先，我们需要一个连接器的表示以及节点上一些集合来存储我们的连接器。\n\n```csharp \npublic class ConnectorViewModel\n{\n    public string Title { get; set; }\n}\n\npublic class NodeViewModel\n{\n    public string Title { get; set; }\n\n    public ObservableCollection<ConnectorViewModel> Input { get; set; } = new ObservableCollection<ConnectorViewModel>();\n    public ObservableCollection<ConnectorViewModel> Output { get; set; } = new ObservableCollection<ConnectorViewModel>();\n}\n\npublic class EditorViewModel\n{\n    public ObservableCollection<NodeViewModel> Nodes { get; } = new ObservableCollection<NodeViewModel>();\n\n    public EditorViewModel()\n    {\n        Nodes.Add(new NodeViewModel\n        {\n            Title = \"Welcome\",\n            Input = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"In\"\n                }\n            },\n            Output = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"Out\"\n                }\n            }\n        });\n    }\n}\n```\n然后将它们绑定到视图。（我们使用了内置的 `NodeInput` 和 `NodeOutput` 作为视图，但也有[其他连接器](连接器概述)。或者根据需要创建自己的连接器。）\n\n```xml\n<nodify:Node Header=\"{Binding Title}\"\n             Input=\"{Binding Input}\"\n             Output=\"{Binding Output}\">\n  <nodify:Node.InputConnectorTemplate>\n      <DataTemplate DataType=\"{x:Type local:ConnectorViewModel}\">\n          <nodify:NodeInput Header=\"{Binding Title}\" />\n      </DataTemplate>\n  </nodify:Node.InputConnectorTemplate>\n  \n  <nodify:Node.OutputConnectorTemplate>\n      <DataTemplate DataType=\"{x:Type local:ConnectorViewModel}\">\n          <nodify:NodeOutput Header=\"{Binding Title}\" />\n      </DataTemplate>\n  </nodify:Node.OutputConnectorTemplate>\n</nodify:Node>\n```\n`Node` 控件支持 `Input` 和 `Output` 连接器，您可以通过重写 `InputConnectorTemplate` 和 `OutputConnectorTemplate` 的默认模板来自定义这些连接器。\n\n从 `Input` 或 `Output` 连接器点击并拖动一根线将创建一个[预备连接](连接概述#预备连接)，我们可以将其转换为实际连接。\n\n**Nodify 最复杂的部分是如何将连接绑定到它们的连接器。** 让我们为连接创建 ViewModel，并在 `EditorViewModel` 中添加连接列表。\n\n```csharp\npublic class ConnectionViewModel\n{\n    public ConnectorViewModel Source { get; set; }\n    public ConnectorViewModel Target { get; set; }\n}\n\npublic class EditorViewModel\n{\n    public ObservableCollection<NodeViewModel> Nodes { get; } = new ObservableCollection<NodeViewModel>();\n    public ObservableCollection<ConnectionViewModel> Connections { get; } = new ObservableCollection<ConnectionViewModel>();\n\n    public EditorViewModel()\n    {\n        var welcome = new NodeViewModel\n        {\n            Title = \"Welcome\",\n            Input = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"In\"\n                }\n            },\n            Output = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"Out\"\n                }\n            }\n        };\n\n        var nodify = new NodeViewModel\n        {\n            Title = \"To Nodify\",\n            Input = new ObservableCollection<ConnectorViewModel>\n            {\n                new ConnectorViewModel\n                {\n                    Title = \"In\"\n                }\n            }\n        };\n\n        Nodes.Add(welcome);\n        Nodes.Add(nodify);\n\n        Connections.Add(new ConnectionViewModel\n        {\n            Source = welcome.Output[0],\n            Target = nodify.Input[0]\n        });\n    }\n}\n```\n然后更新 `ConnectorViewModel` 以具有连接可以附加的 `Anchor` 点。（这需要是响应式的，因此我们将在视图模型中实现 INotifyPropertyChanged 接口）。\n\n> 注意：Point 类型必须来自 System.Windows。\n\n```csharp\npublic class ConnectorViewModel : INotifyPropertyChanged\n{\n    private Point _anchor;\n    public Point Anchor\n    {\n        set\n        {\n            _anchor = value;\n            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Anchor)));\n        }\n        get => _anchor;\n    }\n\n    public string Title { get; set; }\n\n    public event PropertyChangedEventHandler PropertyChanged;\n}\n```\n\n将 `Anchor` 绑定到连接器的视图，并设置 `Mode=OneWayToSource`。还需将 `IsConnected` 设置为 `True` 以接收 `Anchor` 更新。\n\n```xml\n<nodify:Node.InputConnectorTemplate>\n    <DataTemplate DataType=\"{x:Type local:ConnectorViewModel}\">\n        <nodify:NodeInput Header=\"{Binding Title}\"\n                          IsConnected=\"True\"\n                          Anchor=\"{Binding Anchor, Mode=OneWayToSource}\" />\n    </DataTemplate>\n</nodify:Node.InputConnectorTemplate>\n\n<nodify:Node.OutputConnectorTemplate>\n    <DataTemplate DataType=\"{x:Type local:ConnectorViewModel}\">\n        <nodify:NodeOutput Header=\"{Binding Title}\"\n                           IsConnected=\"True\"\n                           Anchor=\"{Binding Anchor, Mode=OneWayToSource}\"  />\n    </DataTemplate>\n</nodify:Node.OutputConnectorTemplate>\n```\n并将连接绑定到视图，让它们在 `ConnectionTemplate` 中使用我们 `ConnectorViewModel` 的 `Anchor`。有关更多自定义，请参阅[连接概述](连接概述)。\n\n```xml\n<nodify:NodifyEditor ItemsSource=\"{Binding Nodes}\"\n                     Connections=\"{Binding Connections}\">\n    ...\n    <nodify:NodifyEditor.ConnectionTemplate>\n        <DataTemplate DataType=\"{x:Type local:ConnectionViewModel}\">\n            <nodify:LineConnection Source=\"{Binding Source.Anchor}\"\n                                   Target=\"{Binding Target.Anchor}\" />\n        </DataTemplate>\n    </nodify:NodifyEditor.ConnectionTemplate>\n    ...\n```\n\n如果你现在启动应用程序，你会看到有一个连接，并且如果你拖动节点，连接会跟随它们移动。\n\n现在让我们在 `ConnectorViewModel` 中添加 `IsConnected` 属性，以便在实际连接时设置它。并更新 `ConnectionViewModel` 以便在构造时自动连接它们。\n\n```csharp\npublic class ConnectorViewModel : INotifyPropertyChanged\n{\n    private Point _anchor;\n    public Point Anchor\n    {\n        set\n        {\n            _anchor = value;\n            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Anchor)));\n        }\n        get => _anchor;\n    }\n\n    private bool _isConnected;\n    public bool IsConnected\n    {\n        set\n        {\n            _isConnected = value;\n            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(IsConnected)));\n        }\n        get => _isConnected;\n    }\n\n    public string Title { get; set; }\n\n    public event PropertyChangedEventHandler PropertyChanged;\n}\n\npublic class ConnectionViewModel\n{\n    public ConnectionViewModel(ConnectorViewModel source, ConnectorViewModel target)\n    {\n        Source = source;\n        Target = target;\n\n        Source.IsConnected = true;\n        Target.IsConnected = true;\n    }\n\n    public ConnectorViewModel Source { get; }\n    public ConnectorViewModel Target { get; }\n}\n```\n\n并且不要忘记在连接器模板中绑定它。\n\n```xml\nIsConnected=\"{Binding IsConnected}\"\n```\n\n### 将预备连接转换为实际连接。\n\n[预备连接](连接概述#预备连接)从一个 `Source` 开始，当放置到一个 `Target` 上时将完成。源*始终*是一个连接器，目标可以是一个[连接器](连接器概述)、一个[项目容器](项目容器概述)或 `null`。我们现在只关心其他连接器。当连接开始时，执行 `StartedCommand`，该命令接收 `Source` 作为参数。当连接完成时，执行 `CompletedCommand`，该命令接收 `Target` 作为参数。\n\n让我们实现预备连接的视图模型，并将其添加到 `EditorViewModel` 中。\n\n```csharp\npublic class PendingConnectionViewModel\n{\n    private readonly EditorViewModel _editor;\n    private ConnectorViewModel _source;\n\n    public PendingConnectionViewModel(EditorViewModel editor)\n    {\n        _editor = editor;\n        StartCommand = new DelegateCommand<ConnectorViewModel>(source => _source = source);\n        FinishCommand = new DelegateCommand<ConnectorViewModel>(target =>\n        {\n            if (target != null)\n                _editor.Connect(_source, target);\n        });\n    }\n\n    public ICommand StartCommand { get; }\n    public ICommand FinishCommand { get; }\n}\n\npublic class EditorViewModel\n{\n    public PendingConnectionViewModel PendingConnection { get; }\n\n    ...\n\n    public EditorViewModel()\n    {\n        PendingConnection = new PendingConnectionViewModel(this);\n        ...\n    }\n\n    ...\n\n    public void Connect(ConnectorViewModel source, ConnectorViewModel target)\n    {\n        Connections.Add(new ConnectionViewModel(source, target));\n    }\n}\n```\n\n并将其绑定到视图上\n\n```xml\n<nodify:NodifyEditor PendingConnection=\"{Binding PendingConnection}\">\n...\n    <nodify:NodifyEditor.PendingConnectionTemplate>\n        <DataTemplate DataType=\"{x:Type local:PendingConnectionViewModel}\">\n            <nodify:PendingConnection StartedCommand=\"{Binding StartCommand}\"\n                                      CompletedCommand=\"{Binding FinishCommand}\"\n                                      AllowOnlyConnectors=\"True\" />\n        </DataTemplate>\n    </nodify:NodifyEditor.PendingConnectionTemplate>\n...\n</nodify:NodifyEditor>\n```\n这就是创建连接的全部内容。现在你应该可以在连接器之间创建连接了。\n\n### 移除连接\n\n要删除连接，只需监听来自连接器本身或编辑器的断开连接事件，并删除具有连接器作为源或目标的连接。为了简单起见，我们将为 `NodifyEditor` 实现 `DisconnectConnectorCommand`。首先让我们将其添加到 `EditorViewModel`。\n\n```csharp\npublic class EditorViewModel\n{\n    public ICommand DisconnectConnectorCommand { get; }\n\n    ...\n\n    public EditorViewModel()\n    {\n        DisconnectConnectorCommand = new DelegateCommand<ConnectorViewModel>(connector =>\n        {\n            var connection = Connections.First(x => x.Source == connector || x.Target == connector);\n            connection.Source.IsConnected = false;  // This is not correct if there are multiple connections to the same connector\n            connection.Target.IsConnected = false;\n            Connections.Remove(connection);\n        });\n\n        ...\n    }\n}\n```\n\n现在我们将此命令绑定到编辑器试图上。\n\n```xml\n<nodify:NodifyEditor ItemsSource=\"{Binding Nodes}\"\n                     Connections=\"{Binding Connections}\"\n                     PendingConnection=\"{Binding PendingConnection}\"\n                     DisconnectConnectorCommand=\"{Binding DisconnectConnectorCommand}\">\n  ...\n  \n</nodify:NodifyEditor>\n```\n\n### 控制节点位置\n\n如你所见，节点总是在屏幕的左上角。这是因为它们在图中的位置是 (0, 0)。让我们来改变这一点！\n\n在 `NodeViewModel` 中添加一个 `Location` 属性，类型为 `System.Windows.Point`，并触发 `PropertyChanged` 事件。\n\n```csharp\npublic class NodeViewModel : INotifyPropertyChanged\n{\n    private Point _location;\n    public Point Location\n    {\n        set\n        {\n            _location = value;\n            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Location)));\n        }\n        get => _location;\n    }\n\n    public event PropertyChangedEventHandler PropertyChanged;\n\n    ...\n}\n```\n\n并将其绑定到视图\n\n```xml\n<nodify:NodifyEditor ItemsSource=\"{Binding Nodes}\"\n                     Connections=\"{Binding Connections}\"\n                     PendingConnection=\"{Binding PendingConnection}\">\n\n    <nodify:NodifyEditor.ItemContainerStyle>\n        <Style TargetType=\"{x:Type nodify:ItemContainer}\">\n            <Setter Property=\"Location\" \n                    Value=\"{Binding Location}\" />\n        </Style>\n    </nodify:NodifyEditor.ItemContainerStyle>\n\n    ...\n\n</nodify:NodifyEditor>\n```\n\n> 注意：我使用了 ItemContainerStyle 来绑定节点的位置。请查看[项目容器概述](项目容器概述)获取更多信息。\n\n现在你可以在构造节点时设置它们的位置。\n\n## 绘制轴网\n\n绘制简单的网格只需创建一个网格画笔，同时将编辑器的变换持续应用于它，并将该画笔用作编辑器的 `Background`。\n\n因为我们绘制的网格是由线条组成的，而不是填充的，所以编辑器的 `Background` 将具有一些透明度，这意味着我们会看到下面控件的背景颜色。为了解决这个问题，将编辑器包装在一个 `Grid` 中，并设置其 `Background`，或者设置 `Window` 的 `Background`。\n\n使用 `ViewportTransform` 依赖属性使网格随视图移动。\n\n> 注意：示例使用了在 `App.xaml` 中选择的主题提供的静态资源。\n\n```xml\n<Window x:Class=\"MyProject.MainWindow\"\n        xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"\n        xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"\n        xmlns:d=\"http://schemas.microsoft.com/expression/blend/2008\"\n        xmlns:mc=\"http://schemas.openxmlformats.org/markup-compatibility/2006\"\n        xmlns:nodify=\"https://miroiu.github.io/nodify\"\n        mc:Ignorable=\"d\">\n\n    <Window.Resources>\n        <GeometryDrawing x:Key=\"SmallGridGeometry\"\n                        Geometry=\"M0,0 L0,1 0.03,1 0.03,0.03 1,0.03 1,0 Z\"\n                        Brush=\"{StaticResource NodifyEditor.SelectionRectangleBackgroundBrush}\" />\n\n        <GeometryDrawing x:Key=\"LargeGridGeometry\"\n                        Geometry=\"M0,0 L0,1 0.015,1 0.015,0.015 1,0.015 1,0 Z\"\n                        Brush=\"{StaticResource NodifyEditor.SelectionRectangleBackgroundBrush}\" />\n\n        <DrawingBrush x:Key=\"SmallGridLinesDrawingBrush\"\n                    TileMode=\"Tile\"\n                    ViewportUnits=\"Absolute\"\n                    Viewport=\"0 0 20 20\"\n                    Transform=\"{Binding ViewportTransform, ElementName=Editor}\"\n                    Drawing=\"{StaticResource SmallGridGeometry}\" />\n\n        <DrawingBrush x:Key=\"LargeGridLinesDrawingBrush\"\n                    TileMode=\"Tile\"\n                    ViewportUnits=\"Absolute\"\n                    Opacity=\"0.5\"\n                    Viewport=\"0 0 100 100\"\n                    Transform=\"{Binding ViewportTransform, ElementName=Editor}\"\n                    Drawing=\"{StaticResource LargeGridGeometry}\" />\n    </Window.Resources>\n\n    <Grid Background=\"{StaticResource NodifyEditor.BackgroundBrush}\">\n        <nodify:NodifyEditor x:Name=\"Editor\" Background=\"{StaticResource SmallGridLinesDrawingBrush}\" />\n\n        <Grid Background=\"{StaticResource LargeGridLinesDrawingBrush}\"\n              Panel.ZIndex=\"-2\" />\n    </Grid>\n</Window>\n```\n\n> 提示：右键单击并拖动屏幕以移动视图，使用鼠标滚轮放大和缩小。"
