* #GActionGroup represents a group of actions.
|
||||
* #GActionGroup represents a group of actions. Actions can be used to
|
||||
* expose functionality in a structured way, either from one part of a
|
||||
* program to another, or to the outside world. Action groups are often
|
||||
* used together with a #GMenuModel that provides additional
|
||||
* representation data for displaying the actions to the user, e.g. in
|
||||
* a menu.
|
||||
*
|
||||
* The main way to interact with the actions in a GActionGroup is to
|
||||
* activate them with g_action_group_activate_action(). Activating an
|
||||
* action may require a #GVariant parameter. The required type of the
|
||||
* parameter can be inquired with g_action_group_get_action_parameter_type().
|
||||
* Actions may be disabled, see g_action_group_get_action_enabled().
|
||||
* Activating a disabled action has no effect.
|
||||
*
|
||||
* Actions may optionally have a state in the form of a #GVariant. The
|
||||
* current state of an action can be inquired with
|
||||
* g_action_group_get_action_state(). Activating a stateful action may
|
||||
* change its state, but it is also possible to set the state by calling
|
||||
* g_action_group_change_action_state().
|
||||
*
|
||||
* As typical example, consider a text editing application which has an
|
||||
* option to change the current font to 'bold'. A good way to represent
|
||||
* this would be a stateful action, with a boolean state. Activating the
|
||||
* action would toggle the state.
|
||||
*
|
||||
* Each action in the group has a unique name (which is a string). All
|
||||
* method calls, except g_action_group_list_actions() take the name of
|
||||
* an action as an argument.
|
||||
*
|
||||
* Action groups are often used together with a #GMenuModel that provides
|
||||
* additional representation data for the actions.
|
||||
*
|
||||
* The #GActionGroup API is meant to be the 'public' API to the action
|
||||
* group. The calls here are exactly the interaction that 'external
|
||||
* forces' (eg: UI, incoming D-Bus messages, etc.) are supposed to have
