Class Placeholder
If a Placeholder is in the visual tree of a Group, it represents the area of all of the member Parts of that Group. If a Placeholder is in the visual tree of an Adornment, it represents the area of the AdornedElement.
Namespace: Northwoods.Go
Assembly: Northwoods.GoDiagram.WinForms.dll
Syntax
public class Placeholder : GraphObject, IHasContextMenu, IHasToolTipRemarks
Unlike other GraphObjects, the Placeholder measures itself based on these criteria, and not on its own DesiredSize or Scale. It will set its own natural bounds and scale, and in the case of Groups will set the Group's location.
It can only be used in the visual tree of a Group node or an Adornment. There can be at most one Placeholder in a Group or an Adornment.
See the documentation for Group and Adornment for descriptions of the Placeholder roles in each.
