Memory-managed wrapper type.

Type class for types which can be safely cast to Application, for instance with toApplication.

Cast to Application, for types for which this is known to be safe. For general casts, use castTo.

Adds a window to the application.

This call can only happen after the application has started; typically, you should add new application windows in response to the emission of the GIO.Application::activate signal.

This call is equivalent to setting the Window:application property of the window to application.

Normally, the connection between the application and the window will remain until the window is destroyed, but you can explicitly remove it with applicationRemoveWindow.

GTK will keep the application running as long as it has any windows.

Gets the accelerators that are currently associated with the given action.

Returns the list of actions (possibly empty) that the accelerator maps to.

Each item in the list is a detailed action name in the usual form.

This might be useful to discover if an accel already exists in order to prevent installation of a conflicting accelerator (from an accelerator editor or a plugin system, for example). Note that having more than one action per accelerator may not be a bad thing and might make sense in cases where the actions never appear in the same context.

In case there are no actions for a given accelerator, an empty array is returned. NULL is never returned.

It is a programmer error to pass an invalid accelerator string.

If you are unsure, check it with acceleratorParse first.

Gets the “active” window for the application.

The active window is the one that was most recently focused (within the application). This window may not have the focus at the moment if another application has it — this is just the most recently-focused window within this application.

Gets a menu from automatically loaded resources.

See the section on Automatic resources for more information.

Returns the menu model for the menu bar of the application.

Returns the window with the given ID.

The ID of a GtkApplicationWindow can be retrieved with applicationWindowGetId.

Gets a list of the window associated with the application.

The list is sorted by most recently focused window, such that the first element is the currently focused window. (Useful for choosing a parent for a transient window.)

The list that is returned should not be modified in any way. It will only remain valid until the next focus change or window creation or deletion.

Informs the session manager that certain types of actions should be inhibited.

This is not guaranteed to work on all platforms and for all types of actions.

Applications should invoke this method when they begin an operation that should not be interrupted, such as creating a CD or DVD. The types of actions that may be blocked are specified by the flags parameter. When the application completes the operation it should call applicationUninhibit to remove the inhibitor. Note that an application can have multiple inhibitors, and all of them must be individually removed. Inhibitors are also cleared when the application exits.

Applications should not expect that they will always be able to block the action. In most cases, users will be given the option to force the action to take place.

The reason message should be short and to the point.

If a window is given, the session manager may point the user to this window to find out more about why the action is inhibited.

The cookie that is returned by this function should be used as an argument to applicationUninhibit in order to remove the request.

Lists the detailed action names which have associated accelerators.

See applicationSetAccelsForAction.

Creates a new application instance.

When using GtkApplication, it is not necessary to call init manually. It is called as soon as the application gets registered as the primary instance.

Concretely, init is called in the default handler for the GApplication::startup signal. Therefore, GtkApplication subclasses should always chain up in their GIO.Application.startup() handler before using any GTK API.

Note that commandline arguments are not passed to init.

If application_id is not NULL, then it must be valid. See applicationIdIsValid.

If no application ID is given then some features (most notably application uniqueness) will be disabled.

Remove a window from the application.

If the window belongs to the application then this call is equivalent to setting the Window:application property of the window to NULL.

The application may stop running as a result of a call to this function, if the window was the last window of the application.

Sets zero or more keyboard accelerators that will trigger the given action.

The first item in accels will be the primary accelerator, which may be displayed in the UI.

To remove all accelerators for an action, use an empty, zero-terminated array for accels.

For the detailedActionName, see actionParseDetailedName and [Gio.Action.print_detailed_name].

Sets or unsets the menubar for windows of the application.

This is a menubar in the traditional sense.

This can only be done in the primary instance of the application, after it has been registered. GIO.Application.startup() is a good place to call this.

Depending on the desktop environment, this may appear at the top of each window, or at the top of the screen. In some environments, if both the application menu and the menubar are set, the application menu will be presented as if it were the first item of the menubar. Other environments treat the two as completely separate — for example, the application menu may be rendered by the desktop shell while the menubar (if set) remains in each individual window.

Use the base GActionMap interface to add actions, to respond to the user selecting these menu items.

Removes an inhibitor that has been previously established.

See applicationInhibit.

Inhibitors are also cleared when the application exits.

Get the value of the “active-window” property. When overloading is enabled, this is equivalent to

get application #activeWindow

Set the value of the “menubar” property to Nothing. When overloading is enabled, this is equivalent to

clear #menubar

Construct a GValueConstruct with valid value for the “menubar” property. This is rarely needed directly, but it is used by new.

Get the value of the “menubar” property. When overloading is enabled, this is equivalent to

get application #menubar

Set the value of the “menubar” property. When overloading is enabled, this is equivalent to

set application [ #menubar := value ]

Construct a GValueConstruct with valid value for the “register-session” property. This is rarely needed directly, but it is used by new.

Get the value of the “register-session” property. When overloading is enabled, this is equivalent to

get application #registerSession

Set the value of the “register-session” property. When overloading is enabled, this is equivalent to

set application [ #registerSession := value ]

Get the value of the “screensaver-active” property. When overloading is enabled, this is equivalent to

get application #screensaverActive

Emitted when the session manager is about to end the session.

This signal is only emitted if Application:registerSession is true. Applications can connect to this signal and call applicationInhibit with [flagsgtk.ApplicationInhibitFlags.logout] to delay the end of the session until state has been saved.

Connect a signal handler for the queryEnd signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after application #queryEnd callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

Connect a signal handler for the queryEnd signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on application #queryEnd callback

Emitted when a window is added to an application.

See applicationAddWindow.

Connect a signal handler for the windowAdded signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after application #windowAdded callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

Connect a signal handler for the windowAdded signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on application #windowAdded callback

Emitted when a window is removed from an application.

This can happen as a side-effect of the window being destroyed or explicitly through applicationRemoveWindow.

Connect a signal handler for the windowRemoved signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after application #windowRemoved callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

Connect a signal handler for the windowRemoved signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on application #windowRemoved callback
