context_menu - Context menu

Context menus (ADK_Menu) may be assigned in order to extend the default context menu. Context menus refers to an (hierarchical) event action control (ADK_EventActionControl), that may replace default context menus or may be added on top of default context menu. The way context menus are used is determined by option variable GUIFramework.ContextMenu.

When the ContextMenu option is set to IGNORE, no context menu will be shown in the application.

When the ContextMenu option is set to ACCEPT, and the event action control is a single action (no sub_actions list), the action is inserted on top of the action list provided by the default context menu. When the the event action control referenced contains a sub_actions list (multiple action control), all actions defined in the event action list are added on top of the default context menu.

When the ContextMenu option is set to USER, the referenced event action control completely replaces the default context menu.

Sub actions (ADK_EventAction) in the sub actions list may refer to event actions controls, that define sub actions again. Thus, hierarchical context menus may be provided.
