## Detailed Description

Toplevel Window.

This represents all widgets which are physical windows controlled by the window manager.

Gtk::manage() has no effect on Windows because they have no parent containers.

The window will be destroyed when the window manager's close button is clicked. Call set_hide_on_close() if you want it to be hidden instead.

When a window is closed (hidden), it's removed from its application. This can cause Application::run() to return, if it is the last window.

## Member Function Documentation

void Gtk::Window::close | ( |  | ) |

Requests that the window is closed, similar to what happens when a window manager close button is clicked.

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

void Gtk::Window::destroy_ | ( |  | ) |
| protected

void Gtk::Window::fullscreen | ( |  | ) |

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.

You can track the result of this operation via the Gdk::Toplevel::property_state() property, or by listening to notifications of the Gtk::Window::property_fullscreened() property.

void Gtk::Window::fullscreen_on_monitor | ( | const Glib::RefPtr< Gdk::Monitor >& | monitor | ) |

Asks to place window in the fullscreen state on the given monitor.

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

You can track the result of this operation via the Gdk::Toplevel::property_state() property, or by listening to notifications of the Gtk::Window::property_fullscreened() property.

  `true` if window has an explicit window group.

bool Gtk::Window::is_active | ( |  | ) | const

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. 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.

bool Gtk::Window::is_fullscreen | ( |  | ) | const

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 fullscreen() or 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.

bool Gtk::Window::is_maximized | ( |  | ) | const

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 maximize() or 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.

static std::vector<Window*> Gtk::Window::list_toplevels | ( |  | ) |
| static

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, <tt>nullptr</tt>)` first, and then unref all the widgets afterwards.

Returns
  List of toplevel widgets.

void Gtk::Window::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][gtk-X11-arch]) 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 Gdk::Toplevel::property_state() property, or by listening to notifications on the Gtk::Window::property_maximized() property.

void Gtk::Window::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][gtk-X11-arch]) 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 Gdk::Toplevel::property_state() property.

virtual bool Gtk::Window::on_close_request | ( |  | ) |
| protectedvirtual

void Gtk::Window::on_window_hide | ( |  | ) |
| protected

Window& Gtk::Window::operator= | ( | const Window& |  | ) |
| delete

Window& Gtk::Window::operator= | ( | Window&& | src | ) |
| noexcept

void Gtk::Window::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.

void Gtk::Window::present | ( | guint32 | 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 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 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.

Glib::PropertyProxy< Glib::RefPtr<Application> > Gtk::Window::property_application | ( |  | ) |

void Gtk::Window::set_application | ( | const Glib::RefPtr< Application >& | application | ) |

Sets the Gtk::Application associated with the window.

The application will be kept alive for at least as long as it has any windows associated with it. (See Gio::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 closed (hidden), but you can explicitly remove it by calling unset_application().

This is equivalent to calling Gtk::Application::remove_window() and/or Gtk::Application::add_window() on the old/new applications as relevant.

Parameters

  application | A Gtk::Application.

static void Gtk::Window::set_auto_startup_notification | ( | bool | setting = `true` | ) |
| static

By default, after showing the first Gtk::Window, GTK calls 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.

void Gtk::Window::set_child | ( | Widget& | child | ) |

Sets the child widget of window.

Parameters

  child | The child widget.

void Gtk::Window::set_decorated | ( | bool | setting = `true` | ) |

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().

On Windows, this function always works, since there’s no window manager policy involved.

Parameters

  setting | `true` to decorate the window.

static void Gtk::Window::set_default_icon_name | ( | const Glib::ustring & | name | ) |
| static

Sets an icon to be used as fallback for windows that haven't had set_icon_name() called on them.

Parameters

  name | The name of the themed icon.

void Gtk::Window::set_default_size | ( | 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 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 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.

void Gtk::Window::set_default_widget | ( | Gtk::Widget& | default_widget | ) |

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 Gtk::Window.

Parameters

  default_widget | Widget to be the default.

void Gtk::Window::set_deletable | ( | bool | setting = `true` | ) |

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().

On Windows, this function always works, since there’s no window manager policy involved.

Parameters

  setting | `true` to decorate the window as deletable.

void Gtk::Window::set_display | ( | const Glib::RefPtr< Gdk::Display >& | display | ) |

Sets the Gdk::Display 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 Gdk::Display.

void Gtk::Window::set_focus | ( | Gtk::Widget& | focus | ) |

If focus is not the current focus widget, and is focusable, sets it as the focus widget for the 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.

Parameters

  focus | Widget to be the new focus widget.

void Gtk::Window::set_focus_visible | ( | bool | setting = `true` | ) |

Sets the Gtk::Window::property_focus_visible() property.

Parameters

  setting | The new value.

void Gtk::Window::set_hide_on_close | ( | bool | setting = `true` | ) |

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.

void Gtk::Window::set_icon_name | ( | const Glib::ustring & | name | ) |

Sets the icon for the window from a named themed icon.

See the docs for 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.

Since gtkmm 2.18:

Parameters

  name | The name of the themed icon.

void Gtk::Window::set_manage | ( |  | ) |
| override

Overriden to warn that it doesn't make sense to use Gtk::manage() on this class because it has no parent container.

void Gtk::Window::set_mnemonics_visible | ( | bool | setting = `true` | ) |

Sets the Gtk::Window::property_mnemonics_visible() property.

Parameters

  setting | The new value.

void Gtk::Window::set_modal | ( | bool | modal = `true` | ) |

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 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.

Parameters

  modal | Whether the window is modal.

void Gtk::Window::set_resizable | ( | bool | resizable = `true` | ) |

Sets whether the user can resize a window.

Windows are user resizable by default.

Parameters

  resizable | `true` if the user can resize this window.

void Gtk::Window::set_startup_id | ( | const Glib::ustring & | startup_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 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.

void Gtk::Window::set_title | ( | const Glib::ustring & | title | ) |

Sets the title of the Gtk::Window.

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. document filename, for example.

Passing `nullptr` does the same as setting the title to an empty string.

Parameters

  title | Title of the window.

void Gtk::Window::set_titlebar | ( | Widget& | titlebar | ) |

Sets a custom titlebar for window.

A typical widget used here is 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 Gtk::Widget::show().

Parameters

  titlebar | The widget to use as titlebar.

void Gtk::Window::set_transient_for | ( | Window& | parent | ) |

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 set_transient_for() on your behalf.

Passing `nullptr` 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, or `nullptr`.

Glib::SignalProxy<bool()> Gtk::Window::signal_close_request | ( |  | ) |

Slot Prototype:
  `bool on_my_close_request()`

Flags: Run Last

The signal_close_request() signal is emitted when the user clicks on the close button of the window.

Return: `true` to stop other handlers from being invoked for the signal

Glib::SignalProxy<void()> Gtk::Window::signal_keys_changed | ( |  | ) |

Slot Prototype:
  `void on_my_keys_changed()`

Flags: Run First

The signal_keys_changed() signal gets emitted when the set of accelerators or mnemonics that are associated with window changes.

void Gtk::Window::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 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; 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 Gdk::Toplevel::property_state() property, or by listening to notifications of the Gtk::Window::property_fullscreened() property.

void Gtk::Window::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][gtk-X11-arch]) could maximize it again, and not all window managers honor requests to unmaximize.

You can track the result of this operation via the Gdk::Toplevel::property_state() property, or by listening to notifications on the Gtk::Window::property_maximized() property.

void Gtk::Window::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][gtk-X11-arch]) 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 Gdk::Toplevel::property_state() property.

void Gtk::Window::unset_application | ( |  | ) |

Unsets the Application associated with the window.

This could cause the application to exit if it is the application's last window.

void Gtk::Window::unset_child | ( |  | ) |

void Gtk::Window::unset_default_widget | ( |  | ) |

void Gtk::Window::unset_focus | ( |  | ) |

void Gtk::Window::unset_titlebar | ( |  | ) |

Unsets the titlebar.

See also
  set_titlebar()

void Gtk::Window::unset_transient_for | ( |  | ) |

Unsets the current transient window.

See also
  set_transient_for().

Since gtkmm 2.20:
