Interfaces

GtkActionGroup implements GtkBuildable.

Detailed Description

Actions are organised into groups. An action group is essentially a map from names to GtkAction objects. All actions that would make sense to use in a particular context should be in a single group. Multiple action groups may be used for a particular user interface. In fact, it is expected that most nontrivial applications will make use of multiple groups. For example, in an application that can edit multiple documents, one group holding global actions (e.g. quit, about, new), and one group per document holding actions that act on that document (eg. save, cut/copy/paste, etc). Each window's menus would be constructed from a combination of two action groups. Accelerators are handled by the GTK+ accelerator map. All actions are assigned an accelerator path (which normally has the form / \var{group-name} / \var{action-name}) and a shortcut is associated with this accelerator path. All menuitems and toolitems take on this accelerator path. The GTK+ accelerator map code makes sure that the correct shortcut is displayed next to the menu item.

GtkActionGroup as GtkBuildable

The GtkActionGroup implementation of the GtkBuildable interface accepts GtkAction objects as elements in UI definitions. Note that it is probably more common to define actions and action groups in the code, since they are directly related to what the code can do. The GtkActionGroup implementation of the GtkBuildable interface supports a custom element, which has attributes named key and modifiers and allows to specify accelerators. This is similar to the element of GtkWidget, the main difference is that it doesn't allow you to specify a signal. A GtkDialog UI definition fragment.

Structures

GtkActionGroup

The GtkActionGroup struct contains only private members and should not be accessed directly.

GtkActionEntry

GtkActionEntry structs are used with gtkActionGroupAddActions to construct actions. GtkActionEntry is a transparent-type.

name: The name of the action.
stock_id: The stock id for the action, or the name of an icon from the icon theme.
label: The label for the action. This field should typically be marked for translation, see gtkActionGroupSetTranslationDomain. If label is NULL, the label of the stock item with id stock.id is used.
accelerator: The accelerator for the action, in the format understood by gtkAcceleratorParse.
tooltip: The tooltip for the action. This field should typically be marked for translation, see gtkActionGroupSetTranslationDomain.
callback: The function to call when the action is activated.

GtkToggleActionEntry

GtkToggleActionEntry structs are used with gtkActionGroupAddToggleActions to construct toggle actions. GtkToggleActionEntry is a transparent-type.

name: The name of the action.
stock_id: The stock id for the action, or the name of an icon from the icon theme.
label: The label for the action. This field should typically be marked for translation, see gtkActionGroupSetTranslationDomain.
accelerator: The accelerator for the action, in the format understood by gtkAcceleratorParse.
tooltip: The tooltip for the action. This field should typically be marked for translation, see gtkActionGroupSetTranslationDomain.
callback: The function to call when the action is activated.
is_active: The initial state of the toggle action.

GtkRadioActionEntry

GtkRadioActionEntry structs are used with gtkActionGroupAddRadioActions to construct groups of radio actions. GtkRadioActionEntry is a transparent-type.

name: The name of the action.
stock_id: The stock id for the action, or the name of an icon from the icon theme.
label: The label for the action. This field should typically be marked for translation, see gtkActionGroupSetTranslationDomain.
accelerator: The accelerator for the action, in the format understood by gtkAcceleratorParse.
tooltip: The tooltip for the action. This field should typically be marked for translation, see gtkActionGroupSetTranslationDomain.
value: The value to set on the radio action. See gtkRadioActionGetCurrentValue.

Convenient Construction

gtkActionGroup is the equivalent of gtkActionGroupNew.

Signals

connect-proxy(action.group, action, proxy, user.data)

The ::connect-proxy signal is emitted after connecting a proxy to an action in the group. Note that the proxy may have been connected to a different action before. This is intended for simple customizations for which a custom action class would be too clumsy, e.g. showing tooltips for menuitems in the statusbar. GtkUIManager proxies the signal and provides global notification just before any action is connected to a proxy, which is probably more convenient to use. Since 2.4

action.group: the group
action: the action
proxy: the proxy
user.data: user data set when the signal handler was connected.

disconnect-proxy(action.group, action, proxy, user.data)

The ::disconnect-proxy signal is emitted after disconnecting a proxy from an action in the group. GtkUIManager proxies the signal and provides global notification just before any action is connected to a proxy, which is probably more convenient to use. Since 2.4

action.group: the group
action: the action
proxy: the proxy
user.data: user data set when the signal handler was connected.

post-activate(action.group, action, user.data)

The ::post-activate signal is emitted just after the action in the action.group is activated This is intended for GtkUIManager to proxy the signal and provide global notification just after any action is activated. Since 2.4

action.group: the group
action: the action
user.data: user data set when the signal handler was connected.

pre-activate(action.group, action, user.data)

The ::pre-activate signal is emitted just before the action in the action.group is activated This is intended for GtkUIManager to proxy the signal and provide global notification just before any action is activated. Since 2.4

action.group: the group
action: the action
user.data: user data set when the signal handler was connected.

Properties
