NodeShape::AbsoluteBoundsDomainPropertyId Field
Visual Studio 2015
The GUID used to identify the AbsoluteBounds domain property.
Assembly: Microsoft.VisualStudio.Modeling.Sdk.Diagrams.12.0 (in Microsoft.VisualStudio.Modeling.Sdk.Diagrams.12.0.dll)
Field Value
Type: System::GuidUse this in a T:Microsoft.VisualStudio.Modeling.Diagrams.ChangeRule to respond to changes in the absolute bounds. A Change Rule is performed inside the transaction that triggered the rule, usually just before the end of the transaction.
// This rule responds to changes in location and size of MyShape,
// which is declared in DSL Definition.
[RuleOn(typeof(MyShape))]
public sealed class MyShapeMoveRule : ChangeRule
{
public override void ElementPropertyChanged(ElementPropertyChangedEventArgs e)
{
MyShape shape = e.ModelElement as MyShape;
if (shape == null) return;
if (shape.Store.InSerializationTransaction) return;
if (!shape.IsNestedChild) return;
if (e.DomainProperty.Id == NodeShape.AbsoluteBoundsDomainPropertyId)
{
shape.ParentShape.NestedChildShapes.Move(shape,
shape.ParentShape.NestedChildShapes.Count - 1);
// this.Diagram.NeedsRenumber should be set after
// re-ordering the child shapes. It should also be
// set after the user invokes Undo or Redo; but
// the rule is not called in Undo or Redo.
// So instead, we will put the NeedsRenumber call
// in an override of OnAbsoluteBoundsChanged, which
// is always called.
}
}
}
// Register the rule.
