protected property TControl.OnMouseWheelRight : TMouseWheelUpDownEvent |
OnMouseWheelRight is a TMouseWheelUpDownEvent property with the event handler signalled when the mouse wheel is "tilted" towards the right. It is signalled (when assigned) from the DoMouseWheelRight method, and occurs when the LM_MOUSEHWHEEL message is handled in the WMMouseHWheel method.
Applications can implement and assign a TMouseWheelUpDownEvent to perform actions needed when the event has occurred in the control. The arguments to the event handler include:
There are several horizontal mouse wheel event handlers, and they are signalled in order until a handler is found that responds to the event notification. These include:
OnMouseWheelRight, and the other horizontal mouse wheel event handlers, require a mouse with a tilting scroll wheel to generate the event notification.
