Control.addOnMouseWheel

Assigns a delegate to the mouseWheel event.

Syntax

public final void addOnMouseWheel( MouseEventHandler value )

Parameters

value

The MouseEventHandler delegate to be notified when the event occurs.

Remarks

Passing an event handler as a parameter to this method is equivalent to setting the mouseWheel event to that method in the Properties window. The mouseWheel event occurs when the user rotates the mouse wheel while this control has the focus. Pressing the mouse wheel generates a mouseDown event with the middle button pressed.
