The right mouse button can be used to generate a RightClick event when a widget has the "RightClick" transmit property. The RightClick transmit property can be set in the Zim Screen Painter. Widgets that have the RightClick property cause FORM INPUT to terminate when they are clicked by the right mouse button. When the RightClick property causes FORM INPUT to terminate, the event structure's EventName is set to "RightClick", the Event.EventType is set to formfield ,and the Event.EventTag is set to the tag of the formfield that was clicked on. A right mouse click does not change the current field, and is detected only if it occurs on a widget in the current graphical window.
The $MouseSubscript, $MouseFieldNum and $MouseFormNum variables now contains information about the field that was right clicked upon.
