Release 10.1A: OpenEdge Development:
Progress 4GL Reference

Mouse events

Progress 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 Progress processes mouse events in the 4GL, see the chapter on handling user input in OpenEdge Development: Programming Interfaces .

Portable mouse events

Table 96 lists the mouse events that apply to all mice, no matter how the buttons are configured.
