TriggerNode Attribute
Data Type: TreeNode
4GL Access: R
The TriggerNode attribute specifies the node that was either collapsed, expanded, or has its label changed. This is only meaningful during execution of Collapsed, Expanded, or LabelChanged event blocks.
During a drag-and-drop operation, the TriggerNode attribute is set to the node from which the drag operation was initiated.
