JIDLMouseWheelListener

Declaration

public interface JIDLMouseWheelListener

All Known Implementing Classes:

JIDLCanvas

Description

The listener interface for receiving mouse wheel events on a JIDLCanvas.

The class that is interested in processing an IDL mouse wheel event implements this interface. The listener object created from that class is then registered with the JIDLCanvas using the addIDLMouseWheelListener method. The listener is unregistered with the removeIDLMouseWheelListener.

The JIDLCanvas automatically handles mouse wheel events whether a program registers an additional JIDLMouseWheelListener or not. The JIDLCanvas is itself a JIDLMouseWheelListener and provides default behavior for the event.

Note: Clients should not register to listen to JIDLCanvas MouseWheelEvents using a MouseWheelListener, preferring the JIDLMouseWheelListener instead.

Note: The Java convention for mouse wheel direction is the opposite of IDL’s. This is transparent to IDL applications because when the MouseWheelEvent is passed to IDL, the sign is flipped.
