public class Window extends Widget
A `GtkWindow` is a toplevel window which can contain other widgets.

![An example GtkWindow](window.png)

Windows normally have decorations that are under the control
of the windowing system and allow the user to manipulate the window
(resize it, move it, close it,...).

# GtkWindow as GtkBuildable

The `GtkWindow` implementation of the [iface@Gtk.Buildable] interface supports
setting a child as the titlebar by specifying “titlebar” as the “type”
attribute of a <child> element.

# CSS nodes

```
window.background [.csd / .solid-csd / .ssd] [.maximized / .fullscreen / .tiled]
├── <child>
╰── <titlebar child>.titlebar [.default-decoration]
```

`GtkWindow` has a main CSS node with name window and style class .background.

Style classes that are typically used with the main CSS node are .csd (when
client-side decorations are in use), .solid-csd (for client-side decorations
without invisible borders), .ssd (used by mutter when rendering server-side
decorations). GtkWindow also represents window states with the following
style classes on the main node: .maximized, .fullscreen, .tiled (when supported,
also .tiled-top, .tiled-left, .tiled-right, .tiled-bottom).

`GtkWindow` subclasses often add their own discriminating style classes,
such as .dialog, .popup or .tooltip.

Generally, some CSS properties don't make sense on the toplevel window node,
such as margins or padding. When client-side decorations without invisible
borders are in use (i.e. the .solid-csd style class is added to the
main window node), the CSS border of the toplevel window is used for
resize drags. In the .csd case, the shadow area outside of the window
can be used to resize it.

`GtkWindow` adds the .titlebar and .default-decoration style classes to the
widget that is added as a titlebar child.

# Accessibility

`GtkWindow` uses the %GTK_ACCESSIBLE_ROLE_WINDOW role.

# Actions

`GtkWindow` defines a set of built-in actions:
- `default.activate`: Activate the default widget.
- `window.minimize`: Minimize the window.
- `window.toggle-maximized`: Maximize or restore the window.
- `window.close`: Close the window.

  • Field Details

  • Constructor Details

    • Window

      public Window(PointerContainer pointer)

    • Window

      public Window()
      Creates a new `GtkWindow`.

      To get an undecorated window (no window borders), use
      [method@Gtk.Window.set_decorated].

      All top-level windows created by gtk_window_new() are stored
      in an internal top-level window list. This list can be obtained
      from [func@Gtk.Window.list_toplevels]. Due to GTK keeping a
      reference to the window internally, gtk_window_new() does not
      return a reference to the caller.

      To delete a `GtkWindow`, call [method@Gtk.Window.destroy].

  • Method Details

    • getClassHandler

      public static ClassHandler getClassHandler()

    • close

      public void close()
      Requests that the window is closed.

      This is similar to what happens when a window manager
      close button is clicked.

      This function can be used with close buttons in custom
      titlebars.

    • destroy

      public void destroy()
      Drop the internal reference GTK holds on toplevel windows.

    • fullscreen

      public void fullscreen()
      Asks to place @window in the fullscreen state.

      Note that you shouldn’t assume the window is definitely fullscreen
      afterward, because other entities (e.g. the user or window manager
      unfullscreen it again, and not all window managers honor requests
      to fullscreen windows.

      You can track the result of this operation via the
      [property@Gdk.Toplevel:state] property, or by listening to
      notifications of the [property@Gtk.Window:fullscreened] property.

    • fullscreenOnMonitor

      public void fullscreenOnMonitor(@Nonnull Monitor monitor)
      Asks to place @window in the fullscreen state on the given @monitor.

      Note that you shouldn't assume the window is definitely fullscreen
      afterward, or that the windowing system allows fullscreen windows on
      any given monitor.

      You can track the result of this operation via the
      [property@Gdk.Toplevel:state] property, or by listening to
      notifications of the [property@Gtk.Window:fullscreened] property.
      Parameters:
      monitor - which monitor to go fullscreen on

    • getApplication

      public Application getApplication()
      Gets the `GtkApplication` associated with the window.
      Returns:
      a `GtkApplication`

    • getChild

      public Widget getChild()
      Gets the child widget of @window.
      Returns:
      the child widget of @window

    • getDecorated

      public boolean getDecorated()
      Returns whether the window has been set to have decorations.
      Returns:
      %TRUE if the window has been set to have decorations

    • getDefaultSize

      public void getDefaultSize(@Nullable Int width, @Nullable Int height)
      Gets the default size of the window.

      A value of 0 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.
      Parameters:
      width - location to store the default width
      height - location to store the default height

    • getDefaultWidget

      public Widget getDefaultWidget()
      Returns the default widget for @window.
      Returns:
      the default widget

    • getDeletable

      public boolean getDeletable()
      Returns whether the window has been set to have a close button.
      Returns:
      %TRUE if the window has been set to have a close button

    • getDestroyWithParent

      public boolean getDestroyWithParent()
      Returns whether the window will be destroyed with its transient parent.
      Returns:
      %TRUE if the window will be destroyed with its transient parent.

    • getFocus

      public Widget getFocus()
      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.
      Returns:
      the currently focused widget

    • getFocusVisible

      public boolean getFocusVisible()
      Gets whether “focus rectangles” are supposed to be visible.
      Returns:
      %TRUE if “focus rectangles” are supposed to be visible in this window.

    • getGroup

      public WindowGroup getGroup()
      Returns the group for @window.

      If the window has no group, then the default group is returned.
      Returns:
      the `GtkWindowGroup` for a window or the default group

    • getHandleMenubarAccel

      public boolean getHandleMenubarAccel()
      Returns whether this window reacts to F10 key presses by
      activating a menubar it contains.
      Returns:
      %TRUE if the window handles F10

    • getHideOnClose

      public boolean getHideOnClose()
      Returns whether the window will be hidden when the close button is clicked.
      Returns:
      %TRUE if the window will be hidden

      public Str getIconName()
      Returns the name of the themed icon for the window.
      Returns:
      the icon name

    • getMnemonicsVisible

      public boolean getMnemonicsVisible()
      Gets whether mnemonics are supposed to be visible.
      Returns:
      %TRUE if mnemonics are supposed to be visible in this window.

    • getModal

      public boolean getModal()
      Returns whether the window is modal.
      Returns:
      %TRUE if the window is set to be modal and establishes a grab when shown

    • getResizable

      public boolean getResizable()
      Gets the value set by gtk_window_set_resizable().
      Returns:
      %TRUE if the user can resize the window

    • getTitle

      public Str getTitle()
      Retrieves the title of the window.
      Returns:
      the title of the window

    • getTitlebar

      public Widget getTitlebar()
      Returns the custom titlebar that has been set with
      gtk_window_set_titlebar().
      Returns:
      the custom titlebar

    • getTransientFor

      public Window getTransientFor()
      Fetches the transient parent for this window.
      Returns:
      the transient parent for this window

    • hasGroup

      public boolean hasGroup()
      Returns whether @window has an explicit window group.
      Returns:
      %TRUE if @window has an explicit window group.

    • isActive

      public boolean isActive()
      Returns whether the window is part of the current active toplevel.

      The active toplevel is the window receiving keystrokes.

      The return value is %TRUE if the window is active toplevel itself.
      You might use this function if you wanted to draw a widget
      differently in an active window from a widget in an inactive window.
      Returns:
      %TRUE if the window part of the current active window.

    • isFullscreen

      public boolean isFullscreen()
      Retrieves the current fullscreen state of @window.

      Note that since fullscreening is ultimately handled by the window
      manager and happens asynchronously to an application request, you
      shouldn’t assume the return value of this function changing
      immediately (or at all), as an effect of calling
      [method@Gtk.Window.fullscreen] or [method@Gtk.Window.unfullscreen].

      If the window isn't yet mapped, the value returned will whether the
      initial requested state is fullscreen.
      Returns:
      whether the window has a fullscreen state.

    • isMaximized

      public boolean isMaximized()
      Retrieves the current maximized state of @window.

      Note that since maximization is ultimately handled by the window
      manager and happens asynchronously to an application request, you
      shouldn’t assume the return value of this function changing
      immediately (or at all), as an effect of calling
      [method@Gtk.Window.maximize] or [method@Gtk.Window.unmaximize].

      If the window isn't yet mapped, the value returned will whether the
      initial requested state is maximized.
      Returns:
      whether the window has a maximized state.

    • maximize

      public void maximize()
      Asks to maximize @window, so that it fills the screen.

      Note that you shouldn’t assume the window is definitely maximized
      afterward, because other entities (e.g. the user or window manager
      could unmaximize it again, and not all window managers support
      maximization.

      It’s permitted to call this function before showing a window,
      in which case the window will be maximized when it appears onscreen
      initially.

      You can track the result of this operation via the
      [property@Gdk.Toplevel:state] property, or by listening to
      notifications on the [property@Gtk.Window:maximized]
      property.

    • minimize

      public void minimize()
      Asks to minimize the specified @window.

      Note that you shouldn’t assume the window is definitely minimized
      afterward, because the windowing system might not support this
      functionality; other entities (e.g. the user or the window manager
      could unminimize it again, or there may not be a window manager in
      which case minimization isn’t possible, etc.

      It’s permitted to call this function before showing a window,
      in which case the window will be minimized before it ever appears
      onscreen.

      You can track result of this operation via the
      [property@Gdk.Toplevel:state] property.

    • present

      public void present()
      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.

    • presentWithTime

      public void presentWithTime(int timestamp)
      Presents a window to the user.

      This may mean raising the window in the stacking order,
      unminimizing 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.

      If @window is hidden, this function calls [method@Gtk.Widget.show]
      as well.

      This function should be used when the user tries to open a window
      that’s already open. Say for example the preferences dialog is
      currently open, and the user chooses Preferences from the menu
      a second time; use [method@Gtk.Window.present] to move the
      already-open dialog where the user can see it.

      Presents a window to the user in response to a user interaction.
      The timestamp should be gathered when the window was requested
      to be shown (when clicking a link for example), rather than once
      the window is ready to be shown.
      Parameters:
      timestamp - the timestamp of the user interaction (typically a button or key press event) which triggered this call

    • setApplication

      public void setApplication(@Nullable Application application)
      Sets or unsets the `GtkApplication` associated with the window.

      The application will be kept alive for at least as long as it has
      any windows associated with it (see g_application_hold() for a way
      to keep it alive without windows).

      Normally, the connection between the application and the window will
      remain until the window is destroyed, but you can explicitly remove
      it by setting the @application to %NULL.

      This is equivalent to calling [method@Gtk.Application.remove_window]
      and/or [method@Gtk.Application.add_window] on the old/new applications
      as relevant.
      Parameters:
      application - a `GtkApplication`, or %NULL to unset

    • setChild

      public void setChild(@Nullable Widget child)
      Sets the child widget of @window.
      Parameters:
      child - the child widget

    • setDecorated

      public void setDecorated(boolean setting)
      Sets whether the window should be decorated.

      By default, windows are decorated with a title bar, resize
      controls, etc. Some window managers 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
      [method@Gtk.Widget.show].

      On Windows, this function always works, since there’s no window manager
      policy involved.
      Parameters:
      setting - %TRUE to decorate the window

    • setDefaultSize

      public void setDefaultSize(int width, int height)
      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.

      Unlike [method@Gtk.Widget.set_size_request], which sets a size
      request for a widget and thus would keep users from shrinking
      the window, this function only sets the initial size, just as
      if the user had resized the window themselves. Users can still
      shrink the window again as they normally would. Setting a default
      size of -1 means to use the “natural” default size (the size request
      of the window).

      The default size of a window only affects the first time a window is
      shown; if a window is hidden and re-shown, it will remember the size
      it had prior to hiding, rather than using the default size.

      Windows can’t actually be 0x0 in size, they must be at least 1x1, but
      passing 0 for @width and @height is OK, resulting in a 1x1 default size.

      If you use this function to reestablish a previously saved window size,
      note that the appropriate size to save is the one returned by
      [method@Gtk.Window.get_default_size]. Using the window allocation
      directly will not work in all circumstances and can lead to growing
      or shrinking windows.
      Parameters:
      width - width in pixels, or -1 to unset the default width
      height - height in pixels, or -1 to unset the default height

    • setDefaultWidget

      public void setDefaultWidget(@Nullable Widget default_widget)
      Sets the default widget.

      The default widget is the widget that is activated when the user
      presses Enter in a dialog (for example).
      Parameters:
      default_widget - widget to be the default to unset the default widget for the toplevel

    • setDeletable

      public void setDeletable(boolean setting)
      Sets whether the window should be deletable.

      By default, windows have a close button in the window frame.
      Some window managers 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 [method@Gtk.Widget.show].

      On Windows, this function always works, since there’s no window
      manager policy involved.
      Parameters:
      setting - %TRUE to decorate the window as deletable

    • setDestroyWithParent

      public void setDestroyWithParent(boolean setting)
      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 are associated with, for example.
      Parameters:
      setting - whether to destroy @window with its transient parent

    • setDisplay

      public void setDisplay(@Nonnull Display display)
      Sets the `GdkDisplay` where the @window is displayed.

      If the window is already mapped, it will be unmapped,
      and then remapped on the new display.
      Parameters:
      display - a `GdkDisplay`

    • setFocus

      public void setFocus(@Nullable Widget focus)
      Sets the focus widget.

      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 [method@Gtk.Widget.grab_focus] instead of this function.
      Parameters:
      focus - widget to be the new focus widget, or %NULL to unset any focus widget for the toplevel window.

    • setFocusVisible

      public void setFocusVisible(boolean setting)
      Sets whether “focus rectangles” are supposed to be visible.
      Parameters:
      setting - the new value

    • setHandleMenubarAccel

      public void setHandleMenubarAccel(boolean handle_menubar_accel)
      Sets whether this window should react to F10 key presses
      by activating a menubar it contains.
      Parameters:
      handle_menubar_accel - %TRUE to make @window handle F10

    • setHideOnClose

      public void setHideOnClose(boolean setting)
      If @setting is %TRUE, then clicking the close button on the window
      will not destroy it, but only hide it.
      Parameters:
      setting - whether to hide the window when it is closed

    • setIconName

      public void setIconName(@Nullable Str name)
      Sets the icon for the window from a named themed icon.

      See the docs for [class@Gtk.IconTheme] for more details.
      On some platforms, the window icon is not used at all.

      Note that this has nothing to do with the WM_ICON_NAME
      property which is mentioned in the ICCCM.
      Parameters:
      name - the name of the themed icon

    • setIconName

      public void setIconName(String name)
      Sets the icon for the window from a named themed icon.

      See the docs for [class@Gtk.IconTheme] for more details.
      On some platforms, the window icon is not used at all.

      Note that this has nothing to do with the WM_ICON_NAME
      property which is mentioned in the ICCCM.
      Parameters:
      name - the name of the themed icon

    • setMnemonicsVisible

      public void setMnemonicsVisible(boolean setting)
      Sets whether mnemonics are supposed to be visible.
      Parameters:
      setting - the new value

    • setModal

      public void setModal(boolean modal)
      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 [method@Gtk.Window.set_transient_for] to make the dialog transient
      for the parent; most window managers will then disallow lowering the
      dialog below the parent.
      Parameters:
      modal - whether the window is modal

    • setResizable

      public void setResizable(boolean resizable)
      Sets whether the user can resize a window.

      Windows are user resizable by default.
      Parameters:
      resizable - %TRUE if the user can resize this window

    • setStartupId

      public void setStartupId(@Nonnull Str startup_id)
      Sets the startup notification ID.

      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 `GdkSurface`.

      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
      [method@Gtk.Window.present] or any equivalent function generating
      a window map event.

      This function is only useful on X11, not with other GTK targets.
      Parameters:
      startup_id - a string with startup-notification identifier

    • setStartupId

      public void setStartupId(String startup_id)
      Sets the startup notification ID.

      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 `GdkSurface`.

      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
      [method@Gtk.Window.present] or any equivalent function generating
      a window map event.

      This function is only useful on X11, not with other GTK targets.
      Parameters:
      startup_id - a string with startup-notification identifier

    • setTitle

      public void setTitle(@Nullable Str title)
      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
      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.

      Passing %NULL does the same as setting the title to an empty string.
      Parameters:
      title - title of the window

    • setTitle

      public void setTitle(String title)
      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
      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.

      Passing %NULL does the same as setting the title to an empty string.
      Parameters:
      title - title of the window

    • setTitlebar

      public void setTitlebar(@Nullable Widget titlebar)
      Sets a custom titlebar for @window.

      A typical widget used here is [class@Gtk.HeaderBar], as it
      provides various features expected of a titlebar while allowing
      the addition of child widgets to it.

      If you set a custom titlebar, GTK will do its best to convince
      the window manager not to put its own titlebar on the window.
      Depending on the system, this function may not work for a window
      that is already visible, so you set the titlebar before calling
      [method@Gtk.Widget.show].
      Parameters:
      titlebar - the widget to use as titlebar

    • setTransientFor

      public void setTransientFor(@Nullable Window parent)
      Dialog windows should be set transient for the main application
      window they were spawned from. This allows window managers to e.g.
      keep the dialog on top of the main window, or center the dialog
      over the main window. [ctor@Gtk.Dialog.new_with_buttons] and other
      convenience functions in GTK will sometimes call
      gtk_window_set_transient_for() on your behalf.

      Passing %NULL for @parent unsets the current transient window.

      On Windows, this function puts the child window on top of the parent,
      much as the window manager would have done on X.
      Parameters:
      parent - parent window

    • unfullscreen

      public void unfullscreen()
      Asks to remove the fullscreen state for @window, and return to
      its previous state.

      Note that you shouldn’t assume the window is definitely not
      fullscreen afterward, because other entities (e.g. the user or
      window manager could fullscreen it again, and not all window
      managers honor requests to unfullscreen windows; normally the
      window will end up restored to its normal state. Just don’t
      write code that crashes if not.

      You can track the result of this operation via the
      [property@Gdk.Toplevel:state] property, or by listening to
      notifications of the [property@Gtk.Window:fullscreened] property.

    • unmaximize

      public void unmaximize()
      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
      maximize it again, and not all window managers honor requests to
      unmaximize.

      You can track the result of this operation via the
      [property@Gdk.Toplevel:state] property, or by listening to
      notifications on the [property@Gtk.Window:maximized] property.

    • unminimize

      public void unminimize()
      Asks to unminimize the specified @window.

      Note that you shouldn’t assume the window is definitely unminimized
      afterward, because the windowing system might not support this
      functionality; other entities (e.g. the user or the window manager
      could minimize it again, or there may not be a window manager in
      which case minimization isn’t possible, etc.

      You can track result of this operation via the
      [property@Gdk.Toplevel:state] property.

    • getDefaultIconName

      public static Str getDefaultIconName()
      Returns the fallback icon name for windows.

      The returned string is owned by GTK and should not
      be modified. It is only valid until the next call to
      [func@Gtk.Window.set_default_icon_name].
      Returns:
      the fallback icon name for windows

    • getToplevels

      public static ListModel getToplevels()
      Returns a list of all existing toplevel windows.

      If you want to iterate through the list and perform actions involving
      callbacks that might destroy the widgets or add new ones, be aware that
      the list of toplevels will change and emit the "items-changed" signal.
      Returns:
      the list of toplevel widgets

    • listToplevels

      public static List listToplevels()
      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.
      Returns:
      list of toplevel widgets

    • setAutoStartupNotification

      public static void setAutoStartupNotification(boolean setting)
      Sets whether the window should request startup notification.

      By default, after showing the first `GtkWindow`, GTK calls
      [method@Gdk.Display.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.

      In that example, you would disable startup notification
      temporarily, show your splash screen, then re-enable it so that
      showing the main window would automatically result in notification.
      Parameters:
      setting - %TRUE to automatically do startup notification

    • setDefaultIconName

      public static void setDefaultIconName(@Nonnull Str name)
      Sets an icon to be used as fallback.

      haven't had [method@Gtk.Window.set_icon_name]
      called on them.
      Parameters:
      name - the name of the themed icon
