ABL supports two types of mouse events—portable and three-button events. You can use portable mouse events to associate triggers with logical actions of any mouse. You can use the three-button mouse events to associate triggers with specific physical actions of a three-button mouse.
The following tables reference portable mouse buttons for portable mouse events and physical mouse buttons for three-button mouse events. For more information on the mapping between portable and physical mouse buttons and how the AVM processes mouse events, see the chapter on handling user input in OpenEdge Development: Programming Interfaces.
