Description
|
|
Packit |
ae235b |
GActionGroup represents a group of actions. Actions can be used to
|
|
Packit |
ae235b |
expose functionality in a structured way, either from one part of a
|
|
Packit |
ae235b |
program to another, or to the outside world. Action groups are often
|
|
Packit |
ae235b |
used together with a GMenuModel that provides additional
|
|
Packit |
ae235b |
representation data for displaying the actions to the user, e.g. in
|
|
Packit |
ae235b |
a menu.
|
|
Packit |
ae235b |
The main way to interact with the actions in a GActionGroup is to
|
|
Packit |
ae235b |
activate them with g_action_group_activate_action(). Activating an
|
|
Packit |
ae235b |
action may require a GVariant parameter. The required type of the
|
|
Packit |
ae235b |
parameter can be inquired with g_action_group_get_action_parameter_type().
|
|
Packit |
ae235b |
Actions may be disabled, see g_action_group_get_action_enabled().
|
|
Packit |
ae235b |
Activating a disabled action has no effect.
|
|
Packit |
ae235b |
Actions may optionally have a state in the form of a GVariant. The
|
|
Packit |
ae235b |
current state of an action can be inquired with
|
|
Packit |
ae235b |
g_action_group_get_action_state(). Activating a stateful action may
|
|
Packit |
ae235b |
change its state, but it is also possible to set the state by calling
|
|
Packit |
ae235b |
g_action_group_change_action_state().
|
|
Packit |
ae235b |
As typical example, consider a text editing application which has an
|
|
Packit |
ae235b |
option to change the current font to 'bold'. A good way to represent
|
|
Packit |
ae235b |
this would be a stateful action, with a boolean state. Activating the
|
|
Packit |
ae235b |
action would toggle the state.
|
|
Packit |
ae235b |
Each action in the group has a unique name (which is a string). All
|
|
Packit |
ae235b |
method calls, except g_action_group_list_actions() take the name of
|
|
Packit |
ae235b |
an action as an argument.
|
|
Packit |
ae235b |
The GActionGroup API is meant to be the 'public' API to the action
|
|
Packit |
ae235b |
group. The calls here are exactly the interaction that 'external
|
|
Packit |
ae235b |
forces' (eg: UI, incoming D-Bus messages, etc.) are supposed to have
|
|
Packit |
ae235b |
with actions. 'Internal' APIs (ie: ones meant only to be accessed by
|
|
Packit |
ae235b |
the action group implementation) are found on subclasses. This is
|
|
Packit |
ae235b |
why you will find - for example - g_action_group_get_action_enabled()
|
|
Packit |
ae235b |
but not an equivalent set() call.
|
|
Packit |
ae235b |
Signals are emitted on the action group in response to state changes
|
|
Packit |
ae235b |
on individual actions.
|
|
Packit |
ae235b |
Implementations of GActionGroup should provide implementations for
|
|
Packit |
ae235b |
the virtual functions g_action_group_list_actions() and
|
|
Packit |
ae235b |
g_action_group_query_action(). The other virtual functions should
|
|
Packit |
ae235b |
not be implemented - their "wrappers" are actually implemented with
|
|
Packit |
ae235b |
calls to g_action_group_query_action().

Queries all aspects of the named action within an action_group
|
|
Packit |
ae235b |
.
|
|
Packit |
ae235b |
This function acquires the information available from
|
|
Packit |
ae235b |
g_action_group_has_action(), g_action_group_get_action_enabled(),
|
|
Packit |
ae235b |
g_action_group_get_action_parameter_type(),
|
|
Packit |
ae235b |
g_action_group_get_action_state_type(),
|
|
Packit |
ae235b |
g_action_group_get_action_state_hint() and
|
|
Packit |
ae235b |
g_action_group_get_action_state() with a single function call.
|
|
Packit |
ae235b |
This provides two main benefits.
|
|
Packit |
ae235b |
The first is the improvement in efficiency that comes with not having
|
|
Packit |
ae235b |
to perform repeated lookups of the action in order to discover
|
|
Packit |
ae235b |
different things about it. The second is that implementing
|
|
Packit |
ae235b |
GActionGroup can now be done by only overriding this one virtual
|
|
Packit |
ae235b |
function.
|
|
Packit |
ae235b |
The interface provides a default implementation of this function that
|
|
Packit |
ae235b |
calls the individual functions, as required, to fetch the
|
|
Packit |

If the action is stateful then this function returns the

Packit |
ae235b |
GVariantType of the state. All calls to
|
|
Packit |
ae235b |
g_action_group_change_action_state() must give a GVariant of this

|
|
Packit |
ae235b |
If the action is not stateful then this function will return NULL.
|
|
Packit |
ae235b |
In that case, g_action_group_get_action_state() will return NULL

ae235b |
named action within action_group
|
|
Packit |
ae235b |
.
|
|
Packit |
ae235b |
If NULL is returned it either means that the action is not stateful

or that there is no hint about the valid range of values for the

|
Packit |
ae235b |
state of the action.
|
|
Packit |
ae235b |
If a GVariant array is returned then each item in the array is a
|
|
Packit |
ae235b |
possible value for the state. If a GVariant pair (ie: two-tuple) is
|
|
Packit |
ae235b |
returned then the tuple specifies the inclusive lower and upper bound
|
|
Packit |
ae235b |
of valid values for the state.
|
|
Packit |
ae235b |
In any case, the information is merely a hint. It may be possible to
|
|
Packit |
ae235b |
have a state value outside of the hinted range and setting a value
|
|
Packit |
ae235b |
within the range may fail.

The return value (if non-NULL) should be freed with
