OnParentChanged Method

In This Topic

Called when this object's parent is changed.

Syntax

protected virtual void OnParentChanged( 
   GoGroup oldgroup,
   GoGroup newgroup
)

Parameters

oldgroup: This GoGroup value is the old value of Parent. The value will be null if the object did not belong to a group but is being added to one.
newgroup: This GoGroup value is the new value of Parent. The value will be null if the object is being removed from a group.

Remarks

When this object is being removed from its group, this method is called before the actual value of Parent is set to null. Otherwise this method is called after the parent has been changed. When this object is being removed from its group, its Layer will be set to null too. When this object is being added to a group, its Layer property will be set to be the same as its new parent's layer. Unlike GoDocument.Changed events, this method will be called even when this object is not part of a document, or when SuspendsUpdates is true. However, this method is not called upon undo or redo of a change of parent. By default this method does nothing. Any implementation of this method should not cause a change in parents or layers.
