TreeView.addOnBeforeCheck

Assigns a delegate to the beforeCheck event.

Syntax

public void addOnBeforeCheck( TreeViewCancelEventHandler value )

Parameters

value

The TreeViewCancelEventHandler delegate to be notified when the event occurs.

Remarks

Passing an event handler as a parameter to this method is equivalent to setting the beforeCheck event to that method in the Properties window. The beforeCheck event occurs when the check box for a tree node is about to be checked. If the event handler cancels this event, the check box will not be checked.
