action_control - Event action control

The event action may refer to an event action control. The event action control, which is also an event action, defines the default settings for the event action. Those might be overwritten by settings in the "local" event action.

Event action controls need not to be defined, i.e. the event action provides sufficient information. In order to refer to the same action e.g. in a tool bar and in a menu, event action controls have to be defined for being able to enable or disable event actions (see also class documentation odabagui::ActionItem).
