Sets our main struct and passes it to the parent class.
Creates a new #GtkApplicationWindow.
Get the main Gtk struct
Gets the #GtkShortcutsWindow that has been set up with a prior call to gtk_application_window_set_help_overlay().
Returns the unique ID of the window. If the window has not yet been added to a #GtkApplication, returns 0.
Returns whether the window will display a menubar for the app menu and menubar as needed.

Move the window to an absolute position. just calls move(int, int). convinience because GdkEvent structs return the position coords as doubles
Gets the value set by gtk_window_set_default_icon_list(). The list is a copy and should be freed with g_list_free(), but the pixbufs in the list have not had their reference count incremented.
Returns the fallback icon name for windows that has been set with gtk_window_set_default_icon_name(). The returned string is owned by GTK+ and should not be modified. It is only valid until the next call to gtk_window_set_default_icon_name().
Returns a list of all existing toplevel windows. The widgets in the list are not individually referenced. If you want to iterate through the list and perform actions involving callbacks that might destroy the widgets, you must call g_list_foreach (result, (GFunc)g_object_ref, NULL) first, and then unref all the widgets afterwards.
By default, after showing the first #GtkWindow, GTK+ calls gdk_notify_startup_complete(). Call this function to disable the automatic startup notification. You might do this if your first window is a splash screen, and you want to delay notification until after your real main window has been shown, for example.
Sets an icon to be used as fallback for windows that haven't had gtk_window_set_icon() called on them from a pixbuf.
Sets an icon to be used as fallback for windows that haven't had gtk_window_set_icon_list() called on them from a file on disk. Warns on failure if @err is %NULL.
Sets an icon list to be used as fallback for windows that haven't had gtk_window_set_icon_list() called on them to set up a window-specific icon list. This function allows you to set up the icon for all windows in your app at once.
Sets an icon to be used as fallback for windows that haven't had gtk_window_set_icon_list() called on them from a named themed icon, see gtk_window_set_icon_name().
Opens or closes the [interactive debugger][interactive-debugging], which offers access to the widget hierarchy of the application and to useful debugging tools.
Activates the default widget for the window, unless the current focused widget has been configured to receive the default action (see gtk_widget_set_receives_default()), in which case the focused widget is activated.
Activates the current focused widget within the window.
Activates mnemonics and accelerators for this #GtkWindow. This is normally called by the default ::key_press_event handler for toplevel windows, however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.
Associate @accel_group with @window, such that calling gtk_accel_groups_activate() on @window will activate accelerators in @accel_group.
Adds a mnemonic to this window.
Starts moving a window. This function is used if an application has window movement grips. When GDK can support it, the window movement will be done using the standard mechanism for the [window manager][gtk-X11-arch] or windowing system. Otherwise, GDK will try to emulate window movement, potentially not all that well, depending on the windowing system.
Starts resizing a window. This function is used if an application has window resizing controls. When GDK can support it, the resize will be done using the standard mechanism for the [window manager][gtk-X11-arch] or windowing system. Otherwise, GDK will try to emulate window resizing, potentially not all that well, depending on the windowing system.
Requests that the window is closed, similar to what happens when a window manager close button is clicked.
Asks to deiconify (i.e. unminimize) the specified @window. Note that you shouldn’t assume the window is definitely deiconified afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch])) could iconify it again before your code which assumes deiconification gets to run.
Asks to place @window in the fullscreen state. Note that you shouldn’t assume the window is definitely full screen afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could unfullscreen it again, and not all window managers honor requests to fullscreen windows. But normally the window will end up fullscreen. Just don’t write code that crashes if not.
Asks to place @window in the fullscreen state. Note that you shouldn't assume the window is definitely full screen afterward.
Gets the value set by gtk_window_set_accept_focus().
Gets the #GtkApplication associated with the window (if any).
Fetches the attach widget for this window. See gtk_window_set_attached_to().
Returns whether the window has been set to have decorations such as a title bar via gtk_window_set_decorated().
Gets the default size of the window. A value of -1 for the width or height indicates that a default size has not been explicitly set for that dimension, so the “natural” size of the window will be used.
Returns the default widget for @window. See gtk_window_set_default() for more details.
Returns whether the window has been set to have a close button via gtk_window_set_deletable().
Returns whether the window will be destroyed with its transient parent. See gtk_window_set_destroy_with_parent ().
Retrieves the current focused widget within the window. Note that this is the widget that would have the focus if the toplevel window focused; if the toplevel window is not focused then gtk_widget_has_focus (widget) will not be %TRUE for the widget.
Gets the value set by gtk_window_set_focus_on_map().
Gets the value of the #GtkWindow:focus-visible property.
Gets the value set by gtk_window_set_gravity().
Returns the group for @window or the default group, if @window is %NULL or if @window does not have an explicit window group.
Determines whether the window may have a resize grip.
Returns whether the window has requested to have its titlebar hidden when maximized. See gtk_window_set_hide_titlebar_when_maximized ().
Gets the value set by gtk_window_set_icon() (or if you've called gtk_window_set_icon_list(), gets the first icon in the icon list).
Retrieves the list of icons set by gtk_window_set_icon_list(). The list is copied, but the reference count on each member won’t be incremented.
Returns the name of the themed icon for the window, see gtk_window_set_icon_name().
Returns the mnemonic modifier for this window. See gtk_window_set_mnemonic_modifier().
Gets the value of the #GtkWindow:mnemonics-visible property.
Returns whether the window is modal. See gtk_window_set_modal().
Fetches the requested opacity for this window. See gtk_window_set_opacity().
This function returns the position you need to pass to gtk_window_move() to keep @window in its current position. This means that the meaning of the returned value varies with window gravity. See gtk_window_move() for more details.
Gets the value set by gtk_window_set_resizable().
If a window has a resize grip, this will retrieve the grip position, width and height into the specified #GdkRectangle.
Returns the role of the window. See gtk_window_set_role() for further explanation.
Returns the #GdkScreen associated with @window.
Obtains the current size of @window.
Gets the value set by gtk_window_set_skip_pager_hint().
Gets the value set by gtk_window_set_skip_taskbar_hint()
Retrieves the title of the window. See gtk_window_set_title().
Returns the custom titlebar that has been set with gtk_window_set_titlebar().
Fetches the transient parent for this window. See gtk_window_set_transient_for().
Gets the type hint for this window. See gtk_window_set_type_hint().
Gets the value set by gtk_window_set_urgency_hint()
Gets the type of the window. See #GtkWindowType.
Returns whether @window has an explicit window group.
Returns whether the input focus is within this GtkWindow. For real toplevel windows, this is identical to gtk_window_is_active(), but for embedded windows, like #GtkPlug, the results will differ.
Asks to iconify (i.e. minimize) the specified @window. Note that you shouldn’t assume the window is definitely iconified afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could deiconify it again, or there may not be a window manager in which case iconification isn’t possible, etc. But normally the window will end up iconified. Just don’t write code that crashes if not.
Returns whether the window is part of the current active toplevel. (That is, the toplevel window receiving keystrokes.) The return value is %TRUE if the window is active toplevel itself, but also if it is, say, a #GtkPlug embedded in the active toplevel. You might use this function if you wanted to draw a widget differently in an active window from a widget in an inactive window. See gtk_window_has_toplevel_focus()
Retrieves the current maximized state of @window.
Asks to maximize @window, so that it becomes full-screen. Note that you shouldn’t assume the window is definitely maximized afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could unmaximize it again, and not all window managers support maximization. But normally the window will end up maximized. Just don’t write code that crashes if not.
Activates the targets associated with the mnemonic.
Asks the [window manager][gtk-X11-arch] to move @window to the given position. Window managers are free to ignore this; most window managers ignore requests for initial window positions (instead using a user-defined placement algorithm) and honor requests after the window has already been shown.
Parses a standard X Window System geometry string - see the manual page for X (type “man X”) for details on this. gtk_window_parse_geometry() does work on all GTK+ ports including Win32 but is primarily intended for an X environment.
Presents a window to the user. This function should not be used as when it is called, it is too late to gather a valid timestamp to allow focus stealing prevention to work correctly.
Presents a window to the user. This may mean raising the window in the stacking order, deiconifying it, moving it to the current desktop, and/or giving it the keyboard focus, possibly dependent on the user’s platform, window manager, and preferences.
Propagate a key press or release event to the focus widget and up the focus container chain until a widget handles @event. This is normally called by the default ::key_press_event and ::key_release_event handlers for toplevel windows, however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.
Reverses the effects of gtk_window_add_accel_group().
Removes a mnemonic from this window.
Hides @window, then reshows it, resetting the default size and position of the window. Used by GUI builders only.
Resizes the window as if the user had done so, obeying geometry constraints. The default geometry constraint is that windows may not be smaller than their size request; to override this constraint, call gtk_widget_set_size_request() to set the window's request to a smaller value.
Determines whether a resize grip is visible for the specified window.
Like gtk_window_resize(), but @width and @height are interpreted in terms of the base size and increment set with gtk_window_set_geometry_hints.
Windows may set a hint asking the desktop environment not to receive the input focus. This function sets this hint.
Sets or unsets the #GtkApplication associated with the window.
Marks @window as attached to @attach_widget. This creates a logical binding between the window and the widget it belongs to, which is used by GTK+ to propagate information such as styling or accessibility to @window as if it was a children of @attach_widget.
By default, windows are decorated with a title bar, resize controls, etc. Some [window managers][gtk-X11-arch] allow GTK+ to disable these decorations, creating a borderless window. If you set the decorated property to %FALSE using this function, GTK+ will do its best to convince the window manager not to decorate the window. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling gtk_widget_show().
The default widget is the widget that’s activated when the user presses Enter in a dialog (for example). This function sets or unsets the default widget for a #GtkWindow. When setting (rather than unsetting) the default widget it’s generally easier to call gtk_widget_grab_default() on the widget. Before making a widget the default widget, you must call gtk_widget_set_can_default() on the widget you’d like to make the default.
Like gtk_window_set_default_size(), but @width and @height are interpreted in terms of the base size and increment set with gtk_window_set_geometry_hints.
Sets the default size of a window. If the window’s “natural” size (its size request) is larger than the default, the default will be ignored. More generally, if the default size does not obey the geometry hints for the window (gtk_window_set_geometry_hints() can be used to set these explicitly), the default size will be clamped to the nearest permitted size.
By default, windows have a close button in the window frame. Some [window managers][gtk-X11-arch] allow GTK+ to disable this button. If you set the deletable property to %FALSE using this function, GTK+ will do its best to convince the window manager not to show a close button. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling gtk_widget_show().
If @setting is %TRUE, then destroying the transient parent of @window will also destroy @window itself. This is useful for dialogs that shouldn’t persist beyond the lifetime of the main window they're associated with, for example.
If @focus is not the current focus widget, and is focusable, sets it as the focus widget for the window. If @focus is %NULL, unsets the focus widget for this window. To set the focus to a particular widget in the toplevel, it is usually more convenient to use gtk_widget_grab_focus() instead of this function.
Windows may set a hint asking the desktop environment not to receive the input focus when the window is mapped. This function sets this hint.
Sets the #GtkWindow:focus-visible property.
This function sets up hints about how a window can be resized by the user. You can set a minimum and maximum size; allowed resize increments (e.g. for xterm, you can only resize by the size of a character); aspect ratios; and more. See the #GdkGeometry struct.
Window gravity defines the meaning of coordinates passed to gtk_window_move(). See gtk_window_move() and #GdkGravity for more details.
Sets whether @window has a corner resize grip.
Tells GTK+ whether to drop its extra reference to the window when gtk_widget_destroy() is called.
If @setting is %TRUE, then @window will request that it’s titlebar should be hidden when maximized. This is useful for windows that don’t convey any information other than the application name in the titlebar, to put the available screen space to better use. If the underlying window system does not support the request, the setting will not have any effect.
Sets up the icon representing a #GtkWindow. This icon is used when the window is minimized (also known as iconified). Some window managers or desktop environments may also place it in the window frame, or display it in other contexts. On others, the icon is not used at all, so your mileage may vary.
Sets the icon for @window. Warns on failure if @err is %NULL.
Sets up the icon representing a #GtkWindow. The icon is used when the window is minimized (also known as iconified). Some window managers or desktop environments may also place it in the window frame, or display it in other contexts. On others, the icon is not used at all, so your mileage may vary.
Sets the icon for the window from a named themed icon. See the docs for #GtkIconTheme for more details. On some platforms, the window icon is not used at all.
Asks to keep @window above, so that it stays on top. Note that you shouldn’t assume the window is definitely above afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could not keep it above, and not all window managers support keeping windows above. But normally the window will end kept above. Just don’t write code that crashes if not.
Asks to keep @window below, so that it stays in bottom. Note that you shouldn’t assume the window is definitely below afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could not keep it below, and not all window managers support putting windows below. But normally the window will be kept below. Just don’t write code that crashes if not.
Sets the mnemonic modifier for this window.
Sets the #GtkWindow:mnemonics-visible property.
Sets a window modal or non-modal. Modal windows prevent interaction with other windows in the same application. To keep modal dialogs on top of main application windows, use gtk_window_set_transient_for() to make the dialog transient for the parent; most [window managers][gtk-X11-arch] will then disallow lowering the dialog below the parent.
Request the windowing system to make @window partially transparent, with opacity 0 being fully transparent and 1 fully opaque. (Values of the opacity parameter are clamped to the [0,1] range.) On X11 this has any effect only on X screens with a compositing manager running. See gtk_widget_is_composited(). On Windows it should work always.
Sets a position constraint for this window. If the old or new constraint is %GTK_WIN_POS_CENTER_ALWAYS, this will also cause the window to be repositioned to satisfy the new constraint.
Sets whether the user can resize a window. Windows are user resizable by default.
This function is only useful on X11, not with other GTK+ targets.
Sets the #GdkScreen where the @window is displayed; if the window is already mapped, it will be unmapped, and then remapped on the new screen.
Windows may set a hint asking the desktop environment not to display the window in the pager. This function sets this hint. (A "pager" is any desktop navigation tool such as a workspace switcher that displays a thumbnail representation of the windows on the screen.)
Windows may set a hint asking the desktop environment not to display the window in the task bar. This function sets this hint.
Startup notification identifiers are used by desktop environment to track application startup, to provide user feedback and other features. This function changes the corresponding property on the underlying GdkWindow. Normally, startup identifier is managed automatically and you should only use this function in special cases like transferring focus from other processes. You should use this function before calling gtk_window_present() or any equivalent function generating a window map event.
Sets the title of the #GtkWindow. The title of a window will be displayed in its title bar; on the X Window System, the title bar is rendered by the [window manager][gtk-X11-arch], so exactly how the title appears to users may vary according to a user’s exact configuration. The title should help a user distinguish this window from other windows they may have open. A good title might include the application name and current document filename, for example.
Sets a custom titlebar for @window.
Dialog windows should be set transient for the main application window they were spawned from. This allows [window managers][gtk-X11-arch] to e.g. keep the dialog on top of the main window, or center the dialog over the main window. gtk_dialog_new_with_buttons() and other convenience functions in GTK+ will sometimes call gtk_window_set_transient_for() on your behalf.
By setting the type hint for the window, you allow the window manager to decorate and handle the window in a way which is suitable to the function of the window in your application.
Windows may set a hint asking the desktop environment to draw the users attention to the window. This function sets this hint.
Don’t use this function. It sets the X Window System “class” and “name” hints for a window. According to the ICCCM, you should always set these to the same value for all windows in an application, and GTK+ sets them to that value by default, so calling this function is sort of pointless. However, you may want to call gtk_window_set_role() on each window in your application, for the benefit of the session manager. Setting the role allows the window manager to restore window positions when loading a saved session.
Asks to stick @window, which means that it will appear on all user desktops. Note that you shouldn’t assume the window is definitely stuck afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch] could unstick it again, and some window managers do not support sticking windows. But normally the window will end up stuck. Just don't write code that crashes if not.
Asks to toggle off the fullscreen state for @window. Note that you shouldn’t assume the window is definitely not full screen afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could fullscreen it again, and not all window managers honor requests to unfullscreen windows. But normally the window will end up restored to its normal state. Just don’t write code that crashes if not.
Asks to unmaximize @window. Note that you shouldn’t assume the window is definitely unmaximized afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could maximize it again, and not all window managers honor requests to unmaximize. But normally the window will end up unmaximized. Just don’t write code that crashes if not.
Asks to unstick @window, which means that it will appear on only one of the user’s desktops. Note that you shouldn’t assume the window is definitely unstuck afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could stick it again. But normally the window will end up stuck. Just don’t write code that crashes if not.
The ::activate-default signal is a [keybinding signal]GtkBindingSignal which gets emitted when the user activates the default widget of @window.
The ::activate-focus signal is a [keybinding signal]GtkBindingSignal which gets emitted when the user activates the currently focused widget of @window.
The ::enable-debugging signal is a [keybinding signal]GtkBindingSignal which gets emitted when the user enables or disables interactive debugging. When @toggle is %TRUE, interactive debugging is toggled on or off, when it is %FALSE, the debugger will be pointed at the widget under the pointer.
The ::keys-changed signal gets emitted when the set of accelerators or mnemonics that are associated with @window changes.
This is a convenience function for launching the default application to show the uri. The uri must be of a form understood by GIO (i.e. you need to install gvfs to get support for uri schemes such as http:// or ftp://, as only local files are handled by GIO itself). Typical examples are - file:///home/gnome/pict.jpg - http://www.gnome.org - mailto:me@gnome.org

Request for the state of the named action within @action_group to be changed to @value.
Checks if the named action within @action_group is currently enabled.
Queries the type of the parameter that must be given when activating the named action within @action_group.
Queries the current state of the named action within @action_group.

Queries the type of the state of the named action within @action_group.
Checks if the named action exists within @action_group.
Lists the actions contained within @action_group.
Queries all aspects of the named action within an @action_group.
Signals that a new action was just added to the group. This signal is emitted after the action has been added and is now visible.
Signals that the enabled status of the named action has changed.
Signals that an action is just about to be removed from the group. This signal is emitted before the action is removed, so the action is still visible and can be queried from the signal handler.
Signals that the state of the named action has changed.

Looks up the action with the name @action_name in @action_map.
Removes the named action from the action map.
#GtkApplicationWindow is a #GtkWindow subclass that offers some extra functionality for better integration with #GtkApplication features. Notably, it can handle both the application menu as well as the menubar. See gtk_application_set_app_menu() and gtk_application_set_menubar().
This class implements the #GActionGroup and #GActionMap interfaces, to let you add window-specific actions that will be exported by the associated #GtkApplication, 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 #GtkActionable interface.
As with #GtkApplication, 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 #GtkSettings:gtk-shell-shows-app-menu and #GtkSettings: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 #GtkApplicationWindow will automatically show a #GtkMenuBar for it. This behaviour can be overridden with the #GtkApplicationWindow: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.

Handling fallback yourself
A simple example
The XML format understood by #GtkBuilder for #GMenuModel consists of a toplevel <menu> element, which contains one or more <item> elements. Each <item> element contains <attribute> and <link> elements with a mandatory name attribute. <link> elements have the same content model as <menu>. Instead of <link name="submenu> or <link name="section">, you can use <submenu> or <section> elements.
Attribute values can be translated using gettext, like other #GtkBuilder content. <attribute> elements can be marked for translation with a translatable="yes" attribute. It is also possible to specify message context and translator comments, using the context and comments attributes. To make use of this, the #GtkBuilder must have been given the gettext domain to use.
The following attributes are used when constructing menu items: - "label": a user-visible string to display - "action": the prefixed name of the action to trigger - "target": the parameter to use when activating the action - "icon" and "verb-icon": names of icons that may be displayed - "submenu-action": name of an action that may be used to determine if a submenu can be opened - "hidden-when": a string used to determine when the item will be hidden. Possible values include "action-disabled", "action-missing", "macos-menubar".
The following attributes are used when constructing sections: - "label": a user-visible string to use as section heading - "display-hint": a string used to determine special formatting for the section. Possible values include "horizontal-buttons". - "text-direction": a string used to determine the #GtkTextDirection to use when "display-hint" is set to "horizontal-buttons". Possible values include "rtl", "ltr", and "none".
The following attributes are used when constructing submenus: - "label": a user-visible string to display - "icon": icon name to display
