GI.Gtk.Objects.Window

A GtkWindow is a toplevel window which can contain other widgets. 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 Buildable interface supports a custom <accel-groups> element, which supports any number of <group> elements representing the GtkAccelGroup objects you want to add to your window (synonymous with gtk_window_add_accel_group().

An example of a UI definition fragment with accel groups: > >class="GtkWindow" > accel-groups > name="accelgroup1"/ > /accel-groups >/object > >... > >class="GtkAccelGroup" id="accelgroup1"/

The GtkWindow implementation of the Buildable interface supports setting a child as the titlebar by specifying “titlebar” as the “type” attribute of a <child> element.

CSS nodes

plain code

window.background
├── decoration
├── <titlebar child>.titlebar [.default-decoration]
╰── <child>

GtkWindow has a main CSS node with name window and style class .background, and a subnode with name decoration.

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: .tiled, .maximized, .fullscreen. Specialized types of window often add their own discriminating style classes, such as .popup or .tooltip.

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

close

windowClose

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m ()

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.

destroy

windowDestroy

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: The window to destroy

-> m ()

Drop the internal reference GTK holds on toplevel windows.

fullscreen

windowFullscreen

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m ()

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.

You can track iconification via the Toplevel:state property

fullscreenOnMonitor

windowFullscreenOnMonitor

Arguments

:: (HasCallStack, MonadIO m, IsWindow a, IsMonitor b)

=> a

window: a Window

-> b

monitor: which monitor to go fullscreen on

-> m ()

Asks to place window in the fullscreen state. Note that you shouldn't assume the window is definitely full screen afterward.

You can track iconification via the Toplevel:state property

Returns: the child widget of window

Gets the child widget of window.

getDecorated

windowGetDecorated

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

getDefaultSize

windowGetDefaultSize

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m (Int32, Int32)

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.

getDefaultWidget

windowGetDefaultWidget

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m (Maybe Widget)

Returns: the default widget, or Nothing if there is none.

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m Bool

Returns: True if the window has been set to have a close button

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m (Maybe Widget)

Returns: the currently focused widget, or Nothing if there is none.

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.

getFocusVisible

windowGetFocusVisible

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

=> a

window: a Window

-> m Bool

Returns: True if the window is set to be modal and establishes a grab when shown

Returns whether the window is modal. See windowSetModal.

getResizable

windowGetResizable

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m Bool

Returns: True if the user can resize the window

Gets the value set by windowSetResizable.

getSize

windowGetSize

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m (Int32, Int32)

Obtains the current size of window.

If window is not visible on screen, this function return the size GTK+ will suggest to the [window manager][gtk-X11-arch] for the initial window size (but this is not reliably the same as the size the window manager will actually select). See: windowSetDefaultSize.

Depending on the windowing system and the window manager constraints, the size returned by this function may not match the size set using windowResize; additionally, since windowResize may be implemented as an asynchronous operation, GTK+ cannot guarantee in any way that this code:

C code

 GtkWindow *window = GTK_WINDOW (gtk_window_new ());
 int width = 500;
 int height = 300;
 gtk_window_resize (window, width, height);

 int new_width, new_height;
 gtk_window_get_size (window, &new_width, &new_height);

will result in new_width and new_height matching width and height, respectively.

This function will return the logical size of the Window, excluding the widgets used in client side decorations; there is, however, no guarantee that the result will be completely accurate because client side decoration may include widgets that depend on the user preferences and that may not be visibile at the time you call this function.

The dimensions returned by this function are suitable for being stored across sessions; use windowSetDefaultSize to restore them when before showing the window.

C code

static void
on_size_allocate (GtkWidget *widget,
                  const GtkAllocation *allocation,
                  int baseline)
{
  int new_width, new_height;

  gtk_window_get_size (GTK_WINDOW (widget), &new_width, &new_height);

  // ...
}

If you are getting a window size in order to position the window on the screen, you should, instead, simply set the window’s semantic type with gtk_window_set_type_hint(), which allows the window manager to e.g. center dialogs. Also, if you set the transient parent of dialogs with windowSetTransientFor window managers will often center the dialog over its parent window. It's much preferred to let the window manager handle these cases rather than doing it yourself, because all apps will behave consistently and according to user or system preferences, if the window manager handles it. Also, the window manager can take into account the size of the window decorations and border that it may add, and of which GTK+ has no knowledge. Additionally, positioning windows in global screen coordinates may not be allowed by the windowing system. For more information, see: gtk_window_set_position().

getTitle

windowGetTitle

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m (Maybe Text)

Returns: the title of the window, or Nothing if none has been set explicitly. The returned string is owned by the widget and must not be modified or freed.

Retrieves the title of the window. See windowSetTitle.

getTitlebar

windowGetTitlebar

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m (Maybe Widget)

Returns: the custom titlebar, or Nothing

Returns the custom titlebar that has been set with windowSetTitlebar.

getToplevels

windowGetToplevels

Arguments

:: (HasCallStack, MonadIO m)

=> m ListModel

Returns: the list of toplevel widgets

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.

getTransientFor

windowGetTransientFor

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m (Maybe Window)

Returns: the transient parent for this window, or Nothing if no transient parent has been set.

Fetches the transient parent for this window. See windowSetTransientFor.

hasGroup

windowHasGroup

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m Bool

Returns: True if window has an explicit window group.

Returns whether window has an explicit window group.

isActive

windowIsActive

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m Bool

Returns: True if the window part of the current active window.

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.

isMaximized

windowIsMaximized

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m Bool

Returns: whether the window has a maximized state.

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 windowMaximize or windowUnmaximize.

listToplevels

windowListToplevels

Arguments

:: (HasCallStack, MonadIO m)

=> m [Widget]

Returns: list of toplevel widgets

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.

maximize

windowMaximize

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m ()

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.

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 Toplevel:state property, or by listening to notifications on the Window:is-maximized property.

minimize

windowMinimize

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m ()

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 Toplevel:state property.

new

windowNew

Arguments

:: (HasCallStack, MonadIO m)

=> m Window

Returns: a new Window.

Creates a new Window, which is a toplevel window that can contain other widgets.

To get an undecorated window (no window borders), use windowSetDecorated.

All top-level windows created by windowNew are stored in an internal top-level window list. This list can be obtained from windowListToplevels. Due to Gtk+ keeping a reference to the window internally, windowNew does not return a reference to the caller.

To delete a Window, call windowDestroy.

present

windowPresent

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m ()

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

windowPresentWithTime

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Word32

timestamp: the timestamp of the user interaction (typically a button or key press event) which triggered this call

-> m ()

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 widgetShow 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 windowPresent 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.

resize

windowResize

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Int32

width: width in pixels to resize the window to

-> Int32

height: height in pixels to resize the window to

-> m ()

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 widgetSetSizeRequest to set the window's request to a smaller value.

If windowResize is called before showing a window for the first time, it overrides any default size set with windowSetDefaultSize.

Windows may not be resized smaller than 1 by 1 pixels.

When using client side decorations, GTK+ will do its best to adjust the given size so that the resulting window size matches the requested size without the title bar, borders and shadows added for the client side decorations, but there is no guarantee that the result will be totally accurate because these widgets added for client side decorations depend on the theme and may not be realized or visible at the time windowResize is issued.

If the GtkWindow has a titlebar widget (see windowSetTitlebar), then typically, windowResize will compensate for the height of the titlebar widget only if the height is known when the resulting GtkWindow configuration is issued. For example, if new widgets are added after the GtkWindow configuration and cause the titlebar widget to grow in height, this will result in a window content smaller that specified by windowResize and not a larger window.

setApplication

windowSetApplication

Arguments

:: (HasCallStack, MonadIO m, IsWindow a, IsApplication b)

=> a

window: a Window

-> Maybe b

application: a Application, or Nothing to unset

-> m ()

Sets or unsets the 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 applicationHold 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 Nothing.

This is equivalent to calling applicationRemoveWindow and/or applicationAddWindow on the old/new applications as relevant.

setAutoStartupNotification

windowSetAutoStartupNotification

Arguments

:: (HasCallStack, MonadIO m)

=> Bool

setting: True to automatically do startup notification

-> m ()

By default, after showing the first Window, 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.

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.

setChild

windowSetChild

Arguments

:: (HasCallStack, MonadIO m, IsWindow a, IsWidget b)

=> a

window: a Window

-> Maybe b

child: the child widget

-> m ()

Sets the child widget of window.

setDecorated

windowSetDecorated

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Bool

setting: True to decorate the window

-> m ()

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 widgetShow.

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

setDefaultIconName

windowSetDefaultIconName

Arguments

:: (HasCallStack, MonadIO m)

=> Text

name: the name of the themed icon

-> m ()

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 windowSetIconName.

setDefaultSize

windowSetDefaultSize

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Int32

width: width in pixels, or -1 to unset the default width

-> Int32

height: height in pixels, or -1 to unset the default height

-> m ()

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 widgetSetSizeRequest, 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).

For some uses, windowResize is a more appropriate function. windowResize changes the current size of the window, rather than the size to be used on initial display. windowResize always affects the window itself, not the geometry widget.

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 windowGetSize. Using the window allocation directly will not work in all circumstances and can lead to growing or shrinking windows.

setDefaultWidget

windowSetDefaultWidget

Arguments

:: (HasCallStack, MonadIO m, IsWindow a, IsWidget b)

=> a

window: a Window

-> Maybe b

defaultWidget: widget to be the default, or Nothing to unset the default widget for the toplevel

-> m ()

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 Window.

setDeletable

windowSetDeletable

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Bool

setting: True to decorate the window as deletable

-> m ()

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 widgetShow.

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

setDestroyWithParent

windowSetDestroyWithParent

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Bool

setting: whether to destroy window with its transient parent

-> m ()

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.

setDisplay

windowSetDisplay

Arguments

:: (HasCallStack, MonadIO m, IsWindow a, IsDisplay b)

=> a

window: a Window.

-> b

display: a Display.

-> m ()

Sets the Display where the window is displayed; if the window is already mapped, it will be unmapped, and then remapped on the new display.

setFocus

windowSetFocus

Arguments

:: (HasCallStack, MonadIO m, IsWindow a, IsWidget b)

=> a

window: a Window

-> Maybe b

focus: widget to be the new focus widget, or Nothing to unset any focus widget for the toplevel window.

-> m ()

If focus is not the current focus widget, and is focusable, sets it as the focus widget for the window. If focus is Nothing, 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 widgetGrabFocus instead of this function.

setFocusVisible

windowSetFocusVisible

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Bool

setting: the new value

-> m ()

Sets the Window:focus-visible property.

setHideOnClose

windowSetHideOnClose

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Bool

setting: whether to hide the window when it is closed

-> m ()

If setting is True, then clicking the close button on the window will not destroy it, but only hide it.

setIconName

windowSetIconName

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Maybe Text

name: the name of the themed icon

-> m ()

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

setInteractiveDebugging

windowSetInteractiveDebugging

Arguments

:: (HasCallStack, MonadIO m)

=> Bool

enable: True to enable interactive debugging

-> m ()

Opens or closes the [interactive debugger][interactive-debugging], which offers access to the widget hierarchy of the application and to useful debugging tools.

setMnemonicsVisible

windowSetMnemonicsVisible

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Bool

setting: the new value

-> m ()

Sets the Window:mnemonics-visible property.

setModal

windowSetModal

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Bool

modal: whether the window is modal

-> m ()

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 windowSetTransientFor to make the dialog transient for the parent; most [window managers][gtk-X11-arch] will then disallow lowering the dialog below the parent.

setResizable

windowSetResizable

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Bool

resizable: True if the user can resize this window

-> m ()

Sets whether the user can resize a window. Windows are user resizable by default.

setStartupId

windowSetStartupId

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Text

startupId: a string with startup-notification identifier

-> m ()

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 windowPresent or any equivalent function generating a window map event.

This function is only useful on X11, not with other GTK+ targets.

setTitle

windowSetTitle

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> Text

title: title of the window

-> m ()

Sets the title of the 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.

setTitlebar

windowSetTitlebar

Arguments

:: (HasCallStack, MonadIO m, IsWindow a, IsWidget b)

=> a

window: a Window

-> Maybe b

titlebar: the widget to use as titlebar

-> m ()

Sets a custom titlebar for window.

A typical widget used here is 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 widgetShow.

setTransientFor

windowSetTransientFor

Arguments

:: (HasCallStack, MonadIO m, IsWindow a, IsWindow b)

=> a

window: a Window

-> Maybe b

parent: parent window, or Nothing

-> m ()

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 windowSetTransientFor on your behalf.

Passing Nothing 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.

unfullscreen

windowUnfullscreen

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m ()

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.

You can track iconification via the Toplevel:state property

unmaximize

windowUnmaximize

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m ()

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.

You can track the result of this operation via the Toplevel:state property, or by listening to notifications on the Window:is-maximized property.

unminimize

windowUnminimize

Arguments

:: (HasCallStack, MonadIO m, IsWindow a)

=> a

window: a Window

-> m ()

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 Toplevel:state property.
