box_control - Tool bar control

The tool bar control refers to the event action control (ADK_EventActionControl) defining the tool bar buttons in its sub action list (sub_actions). Text definitions from the tool bar control context style are overwritten by text definitions provided in the menu context style as soon as not being empty.

When event actions (ADK_EventAction) in the sub actions list refer to event action controls, that contain sub actions, again, the tool bar button becomes a menu button, that shows a list of menu items when being clicked. When not selecting an item from the list, the action defined in the event action control is executed.
