TTreeNode.Deleting property
True if the node has been marked for deletion in the associated tree
view control.
Declaration
property Deleting: Boolean read GetDeleting;Description
Deleting is a read-only
Boolean property which
indicates is the node is marked for deletion. Its value is
True when
ndDeleting has been included in the
States property for
the node. nsDeleting is added to States in the
Destroy method, and
indicates that the node will be freed. The
Delete method in the
TreeView control is called to signal an
OnDeletion
event (when assigned) before references for the node are removed and the
TreeNodes are refreshed. It prevents the Delete method from being
executed more than once.
