- actionAdded
void actionAdded(string actionName)
Emits the #GActionGroup::action-added signal on @action_group.
- actionEnabledChanged
void actionEnabledChanged(string actionName, bool enabled)
Emits the #GActionGroup::action-enabled-changed signal on @action_group.
- actionRemoved
void actionRemoved(string actionName)
Emits the #GActionGroup::action-removed signal on @action_group.
- actionStateChanged
void actionStateChanged(string actionName, Variant state)
Emits the #GActionGroup::action-state-changed signal on @action_group.
- activateAction
void activateAction(string actionName, Variant parameter)
Activate the named action within @action_group.
- addOnActionAdded
gulong addOnActionAdded(void delegate(string, ActionGroupIF) dlg, ConnectFlags connectFlags)
Signals that a new action was just added to the group.
This signal is emitted after the action has been added
and is now visible.
- addOnActionEnabledChanged
gulong addOnActionEnabledChanged(void delegate(string, bool, ActionGroupIF) dlg, ConnectFlags connectFlags)
Signals that the enabled status of the named action has changed.
- addOnActionRemoved
gulong addOnActionRemoved(void delegate(string, ActionGroupIF) dlg, ConnectFlags connectFlags)
Signals that an action is just about to be removed from the group.
This signal is emitted before the action is removed, so the action
is still visible and can be queried from the signal handler.
- addOnActionStateChanged
gulong addOnActionStateChanged(void delegate(string, Variant, ActionGroupIF) dlg, ConnectFlags connectFlags)
Signals that the state of the named action has changed.
- changeActionState
void changeActionState(string actionName, Variant value)
Request for the state of the named action within @action_group to be
changed to @value.
- getActionEnabled
bool getActionEnabled(string actionName)
Checks if the named action within @action_group is currently enabled.
- getActionGroupStruct
GActionGroup* getActionGroupStruct(bool transferOwnership)
- getActionParameterType
VariantType getActionParameterType(string actionName)
Queries the type of the parameter that must be given when activating
the named action within @action_group.
- getActionState
Variant getActionState(string actionName)
Queries the current state of the named action within @action_group.
- getActionStateHint
Variant getActionStateHint(string actionName)
Requests a hint about the valid range of values for the state of the
named action within @action_group.
- getActionStateType
VariantType getActionStateType(string actionName)
Queries the type of the state of the named action within
@action_group.
- hasAction
bool hasAction(string actionName)
Checks if the named action exists within @action_group.
- listActions
string[] listActions()
Lists the actions contained within @action_group.
- queryAction
bool queryAction(string actionName, bool enabled, VariantType parameterType, VariantType stateType, Variant stateHint, Variant state)
Queries all aspects of the named action within an @action_group.

#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.
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 with actions. 'Internal' APIs (ie: ones meant only to be accessed by the action group implementation) are found on subclasses. This is why you will find - for example - g_action_group_get_action_enabled() but not an equivalent set() call.
Signals are emitted on the action group in response to state changes on individual actions.
Implementations of #GActionGroup should provide implementations for the virtual functions g_action_group_list_actions() and g_action_group_query_action(). The other virtual functions should not be implemented - their "wrappers" are actually implemented with calls to g_action_group_query_action().
