Detailed Description

A Gtk::Window subclass with Gtk::Application support.

ApplicationWindow is a Gtk::Window subclass that offers some extra functionality for better integration with Gtk::Application features. Notably, it can handle both the application menu as well as the menubar. See set_app_menu() and set_menubar().

This class derives from Gio::ActionGroup and Gio::ActionMap, to let you add window-specific actions that will be exported by the associated Gtk::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 Gio::MenuModel, or in activate_action(). Gio::ActionGroup::activate_action() does not accept prefixes.

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

As with Gtk::Application, the GDK lock will be acquired when processing actions arriving from other processes and should therefore be held when activating actions locally (if GDK threads are enabled).

The settings Gtk::Settings::property_gtk_shell_shows_app_menu() and Gtk::Settings::property_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. gnome-shell (starting with version 3.4) will display the application menu, but not the menubar.

If the desktop environment does not display the menubar, then Gtk::ApplicationWindow will automatically show a menubar for it. This behaviour can be overridden with property_show_menubar(). If the desktop environment does not display the application menu, then it will automatically be included in the menubar.

Member Function Documentation

activate_action()

bool Gtk::Widget::activate_action	(	const Glib::ustring &	name,
		const Glib::VariantBase &	args = {}
	)

Looks up the action in the action groups associated with the widget and its ancestors, and activates it.

If the action is in an action group added with insert_action_group(), the name is expected to be prefixed with the prefix that was used when the group was inserted.

The arguments must match the action's expected parameter type, as returned by Gio::Action::get_parameter_type().

Parameters

name	The name of the action to activate.
args	Parameters to use, or an empty (invalid) Glib::VariantBase if the action does not expect parameters.

Returns

true if the action was activated, false if the action does not exist.

get_help_overlay() [1/2]

ShortcutsWindow * Gtk::ApplicationWindow::get_help_overlay

(

)

Gets the Gtk::ShortcutsWindow that is associated with window.

See set_help_overlay().

Returns

The help overlay associated with window.

get_help_overlay() [2/2]

const ShortcutsWindow * Gtk::ApplicationWindow::get_help_overlay

(

)

const

Gets the Gtk::ShortcutsWindow that is associated with window.

See set_help_overlay().

Returns

The help overlay associated with window.

get_id()

guint Gtk::ApplicationWindow::get_id

(

)

const

Returns the unique ID of the window.

If the window has not yet been added to a Gtk::Application, returns 0.

Returns

The unique ID for window, or 0 if the window has not yet been added to a Gtk::Application.

get_show_menubar()

bool Gtk::ApplicationWindow::get_show_menubar

(

)

const

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

Returns

true if window will display a menubar when needed.

get_type()

static GType Gtk::ApplicationWindow::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

GtkApplicationWindow * Gtk::ApplicationWindow::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const GtkApplicationWindow * Gtk::ApplicationWindow::gobj ( ) const

inline

Provides access to the underlying C GObject.

property_show_menubar() [1/2]

Glib::PropertyProxy< bool > Gtk::ApplicationWindow::property_show_menubar

(

)

If this property is true, the window will display a menubar unless it is shown by the desktop shell.

See Gtk::Application::set_menubar().

If false, the window will not display a menubar, regardless of whether the desktop shell is showing it or not.

Default value: false

Returns

A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

property_show_menubar() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::ApplicationWindow::property_show_menubar

(

)

const

If this property is true, the window will display a menubar unless it is shown by the desktop shell.

See Gtk::Application::set_menubar().

If false, the window will not display a menubar, regardless of whether the desktop shell is showing it or not.

Default value: false

Returns

A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

set_help_overlay()

void Gtk::ApplicationWindow::set_help_overlay

(

ShortcutsWindow &

help_overlay

)

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 Gtk::ShortcutsWindow.

set_show_menubar()

void Gtk::ApplicationWindow::set_show_menubar

(

bool

show_menubar = true

)

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.

unset_help_overlay()

void Gtk::ApplicationWindow::unset_help_overlay

(

)

Undoes the effect of a previous call to set_help_overlay().

Since gtkmm 3.20:
