Remarks
This is a standard mouse-move tool.
For example, you can change the selection policy in XAML by:
<go:Diagram ...>
<go:Diagram.DragSelectingTool>
<go:DragSelectingTool Include="Intersects" />
</go:Diagram.DragSelectingTool>
</go:Diagram>
Or you can customize the default Northwoods.GoXam.Diagram.DragSelectingTool in code: myDiagram.DragSelectingTool.Include = SearchInclusion.Intersects;
Selection occurs on a mouse up calling SelectInRect with the value of ComputeBoxBounds. If you want real-time selection to occur during the drag:
public class RealtimeDragSelectingTool : DragSelectingTool {
public override void DoMouseMove() {
base.DoMouseMove();
if (this.Active) SelectInRect(ComputeBoxBounds());
}
}
and install in XAML by: <go:Diagram ...>
<go:Diagram.DragSelectingTool>
<local:RealtimeDragSelectingTool Include="Intersects" />
</go:Diagram.DragSelectingTool>
</go:Diagram>
Or you can install in code by: myDiagram.DragSelectingTool = new RealtimeDragSelectingTool() { Include = SearchInclusion.Intersects };
This tool does not utilize any Northwoods.GoXam.Adornments or tool handles.
This tool does not edit the model.
