Description
Occurs whenever the selection has changed from one item to another.
FMX.TreeView.TTreeView.OnChange inherits from FMX.TreeView.TCustomTreeView.OnChange. All content below this line refers to FMX.TreeView.TCustomTreeView.OnChange.
Occurs whenever the selection has changed from one item to another.
Write an OnChange event handler to take specific action when the selected node changes. The Sender parameter is the tree view whose selected item changes.
Note: The OnChange event does not occur for nodes selected using the right mouse button. To respond to changes when the right mouse button is clicked, use the OnMouseUp event.
OnChange is an event handler of type TNotifyEvent.
