ApplicationWindow#

class ApplicationWindow(*args, **kwargs)#

Superclasses: Window, Widget, InitiallyUnowned, Object

Implemented Interfaces: ActionGroup, ActionMap, Accessible, Buildable, ConstraintTarget, Native, Root, ShortcutManager

GtkApplicationWindow is a GtkWindow subclass that integrates with GtkApplication.

Notably, GtkApplicationWindow can handle an application menubar.

This class implements the GActionGroup and GActionMap interfaces, to let you add window-specific actions that will be exported by the associated Application, together with its application-wide actions. Window-specific actions are prefixed with the “win.” prefix and application-wide actions are prefixed with the “app.” prefix. Actions must be addressed with the prefixed name when referring to them from a GMenuModel.

Note that widgets that are placed inside a GtkApplicationWindow can also activate these actions, if they implement the Actionable interface.

The settings gtk_shell_shows_app_menu and gtk_shell_shows_menubar tell GTK whether the desktop environment is showing the application menu and menubar models outside the application as part of the desktop shell. For instance, on OS X, both menus will be displayed remotely; on Windows neither will be.

If the desktop environment does not display the menubar, then GtkApplicationWindow will automatically show a menubar for it. This behaviour can be overridden with the show_menubar property. If the desktop environment does not display the application menu, then it will automatically be included in the menubar or in the windows client-side decorations.

See PopoverMenu for information about the XML language used by GtkBuilder for menu models.

A GtkApplicationWindow with a menubar#

The code sample below shows how to set up a GtkApplicationWindow with a menu bar defined on the Application:

GtkApplication *app = gtk_application_new ("org.gtk.test", 0);

GtkBuilder *builder = gtk_builder_new_from_string (
    "<interface>"
    "  <menu id='menubar'>"
    "    <submenu>"
    "      <attribute name='label' translatable='yes'>_Edit</attribute>"
    "      <item>"
    "        <attribute name='label' translatable='yes'>_Copy</attribute>"
    "        <attribute name='action'>win.copy</attribute>"
    "      </item>"
    "      <item>"
    "        <attribute name='label' translatable='yes'>_Paste</attribute>"
    "        <attribute name='action'>win.paste</attribute>"
    "      </item>"
    "    </submenu>"
    "  </menu>"
    "</interface>",
    -1);

GMenuModel *menubar = G_MENU_MODEL (gtk_builder_get_object (builder, "menubar"));
gtk_application_set_menubar (GTK_APPLICATION (app), menubar);
g_object_unref (builder);

// ...

GtkWidget *window = gtk_application_window_new (app);

Constructors#

class ApplicationWindow

classmethod new(application: Application) → Widget#

Creates a new GtkApplicationWindow.

Parameters:: application – a GtkApplication

Methods#

class ApplicationWindow

get_help_overlay() → ShortcutsWindow | None#

Gets the GtkShortcutsWindow that is associated with window.

See set_help_overlay.

get_id() → int#

Returns the unique ID of the window.

If the window has not yet been added to a GtkApplication, returns 0.

get_show_menubar() → bool#: Returns whether the window will display a menubar for the app menu and menubar as needed.

set_help_overlay(help_overlay: ShortcutsWindow | None = None) → None#

Associates a shortcuts window with the application window.

Additionally, sets up an action with the name win.show-help-overlay to present it.

window takes responsibility for destroying help_overlay.

Parameters:: help_overlay – a GtkShortcutsWindow

set_show_menubar(show_menubar: bool) → None#

Sets whether the window will display a menubar for the app menu and menubar as needed.

Parameters:: show_menubar – whether to show a menubar when needed

Properties#

class ApplicationWindow

props.show_menubar: bool#: The type of the None singleton.
