PmgObject.onMenuFill event is triggered. In this event the

pEvent.Menu parameter).

PmgObject.onMenuSelect event is triggered. In this event it is possible to detect which menu item was selected and execute the corresponding action.

Alt-space key or by clicking the mouse on the application icon.
The
PmaRoot.onSystemMenuFill and
PmaRoot.onSystemMenuSelect events are called.

Pmg object at the moment of calling the menu, means that the context menu can hold different content at each calling.

PmMenu object is valid only in the processing of the
onMenuFill event. It is not allowed to save the reference to this object for the later use.
