# Constructors

windowNew :: IO Window Source #

Create a new top level window.

windowNewPopup :: IO Window Source #

Create a popup window.

# Methods

windowActivateFocus Source #

Arguments

:: WindowClass self |
=> self |
-> IO Bool | returns `True` if a widget got activated.

Activates the current focused widget within the window.

windowActivateDefault Source #

Arguments

:: WindowClass self |
=> self |
-> IO Bool | returns `True` if a widget got activated.

Activates the default widget for the window, unless the current focused widget has been configured to receive the default action (see `ReceivesDefault` in `WidgetFlags`), in which case the focused widget is activated.

windowSetDefaultSize Source #

Arguments

:: WindowClass self |
=> self |
-> Int | `height` - height in pixels, or -1 to unset the default height
-> Int | `width` - width in pixels, or -1 to unset the default width
-> IO () |

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 (`windowSetGeometryHints` can be used to set these explicitly), the default size will be clamped to the nearest permitted size.

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 more control over a window's initial size and how resizing works, investigate `windowSetGeometryHints`.

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.

windowGetDefaultSize Source #

Arguments

:: WindowClass self |
=> self |
-> IO (Int, Int) | `(width, height)` - the default width and height

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.

windowSetPosition :: WindowClass self => self -> WindowPosition -> IO () Source #

Sets a position constraint for this window. If the old or new constraint is `WinPosCenterAlways`, this will also cause the window to be repositioned to satisfy the new constraint.

data WindowPosition Source #

Enum WindowPosition Source # |

Instance details

Methods

succ :: WindowPosition -> WindowPosition Source #

pred :: WindowPosition -> WindowPosition Source #

toEnum :: Int -> WindowPosition Source #

fromEnum :: WindowPosition -> Int Source #

enumFrom :: WindowPosition -> [WindowPosition] Source #

enumFromThen :: WindowPosition -> WindowPosition -> [WindowPosition] Source #

windowIsActive Source #

Arguments

:: WindowClass self |
=> self |
-> IO 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, but also if it is, say, a `Plug` 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 `windowHasToplevelFocus`

- Available since Gtk+ version 2.4

windowHasToplevelFocus Source #

Arguments

:: WindowClass self |
=> self |
-> IO Bool | returns `True` if the the input focus is within this `Window`

Returns whether the input focus is within this `Window`. For real toplevel windows, this is identical to `windowIsActive`, but for embedded windows, like `Plug`, the results will differ.

- Available since Gtk+ version 2.4

windowListToplevels :: IO [Window] Source #

Returns a list of all existing toplevel windows.

windowSetDefault :: (WindowClass self, WidgetClass widget) => self -> Maybe widget -> IO () Source #

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 about. When setting (rather than unsetting) the default widget it's generally easier to call widgetGrabDefault on the widget. Before making a widget the default widget, you must set the `widgetCanDefault` flag on the widget.

windowGetDefaultWidget :: WindowClass self => self -> IO (Maybe Widget) Source #

Returns the default widget for window. See `windowSetDefault` for more details.

- Available since Gtk+ version 2.14

windowAddMnemonic Source #

Arguments

:: (WindowClass self, WidgetClass widget) |
=> self |
-> KeyVal | `keyval` - the mnemonic
-> widget | `target` - the widget that gets activated by the mnemonic
-> IO () |

Adds a mnemonic to this window.

windowRemoveMnemonic Source #

Arguments

:: (WindowClass self, WidgetClass widget) |
=> self |
-> KeyVal | `keyval` - the mnemonic
-> widget | `target` - the widget that gets activated by the mnemonic
-> IO () |

Removes a mnemonic from this window.

windowMnemonicActivate Source #

Arguments

:: WindowClass self |
=> self |
-> KeyVal | `keyval` - the mnemonic
-> [Modifier] | `modifier` - the modifiers
-> IO Bool | return `True` if the activation is done.

Activates the targets associated with the mnemonic.

windowActivateKey Source #

Arguments

:: WindowClass self |
=> self |
-> EventM EKey Bool | return `True` if a mnemonic or accelerator was found and activated.

Activates mnemonics and accelerators for this `Window`. This is normally called by the default `keyPressEvent` 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.

windowPropagateKeyEvent Source #

Arguments

:: WindowClass self |
=> self |
-> EventM EKey Bool | return `True` if a widget in the focus chain handled the event.

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 `keyPressEvent` and `keyReleaseEvent` 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.

windowPresent :: WindowClass self => self -> IO () Source #

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.

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.

If you are calling this function in response to a user interaction, it is preferable to use `windowPresentWithTime`.

windowDeiconify :: WindowClass self => self -> IO () Source #

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) could iconify it again before your code which assumes deiconification gets to run.

You can track iconification via the `windowStateEvent` signal on `Widget`.

windowIconify :: WindowClass self => self -> IO () Source #

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) 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.

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

You can track iconification via the `windowStateEvent` signal on `Widget`.

windowMaximize :: WindowClass self => self -> IO () Source #

Asks to maximize the 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) 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 maximization via the `windowStateEvent` signal on `Widget`.

windowUnmaximize :: WindowClass self => self -> IO () Source #

Asks to unmaximize the window. Note that you shouldn't assume the window is definitely unmaximized afterward, because other entities (e.g. the user or window manager) 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 maximization via the `windowStateEvent` signal on `Widget`.

windowFullscreen :: WindowClass self => self -> IO () Source #

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) 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 the fullscreen state via the `windowStateEvent` signal on `Widget`.

- Available since Gtk+ version 2.2

windowUnfullscreen :: WindowClass self => self -> IO () Source #

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) 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 the fullscreen state via the `windowStateEvent` signal on `Widget`.

- Available since Gtk+ version 2.2

windowSetKeepAbove Source #

Arguments

:: WindowClass self |
=> self |
-> Bool | `setting` - whether to keep `window` above other windows
-> IO () |

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) 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.

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

You can track the above state via the `windowStateEvent` signal on `Widget`.

Note that, according to the Extended Window Manager Hints specification, the above state is mainly meant for user preferences and should not be used by applications e.g. for drawing attention to their dialogs.

- Available since Gtk+ version 2.4

windowSetKeepBelow Source #

Arguments

:: WindowClass self |
=> self |
-> Bool | `setting` - whether to keep `window` below other windows
-> IO () |

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) 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.

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

You can track the below state via the `windowStateEvent` signal on `Widget`.

Note that, according to the Extended Window Manager Hints specification, the above state is mainly meant for user preferences and should not be used by applications e.g. for drawing attention to their dialogs.

- Available since Gtk+ version 2.4

windowSetStartupId :: (WindowClass self, GlibString string) => self -> string -> IO () Source #

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 `windowPresent` or any equivalent function generating a window map event.

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

- Available since Gtk+ version 2.12

windowStick :: WindowClass self => self -> IO () Source #

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) 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.

It's permitted to call this function before showing a window.

You can track stickiness via the `windowStateEvent` signal on `Widget`.

windowUnstick :: WindowClass self => self -> IO () Source #

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) could stick it again. But normally the window will end up stuck. Just don't write code that crashes if not.

You can track stickiness via the `windowStateEvent` signal on `Widget`.

windowAddAccelGroup Source #

Arguments

:: WindowClass self |
=> self |
-> AccelGroup | `accelGroup` - a `AccelGroup`
-> IO () |

Associate `accelGroup` with `window`, such that calling `accelGroupsActivate` on `window` will activate accelerators in `accelGroup`.

windowRemoveAccelGroup Source #

Arguments

windowSetGravity Source #

Arguments

:: WindowClass self |
=> self |
-> Gravity | `gravity` - window gravity
-> IO () |

Window gravity defines the meaning of coordinates passed to `windowMove`. See `windowMove` and `Gravity` for more details.

The default window gravity is `GravityNorthWest` which will typically "do what you mean."

Gets the value set by `windowSetGravity`.

windowSetScreen Source #

Arguments

:: WindowClass self |
=> self |
-> Screen | `screen` - a `Screen`.
-> IO () |

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

- Available since Gtk+ version 2.2

windowGetScreen Source #

Arguments

:: WindowClass self |
=> self |
-> IO Screen | returns a `Screen`.

Returns the `Screen` associated with the window.

- Available since Gtk+ version 2.2

windowBeginResizeDrag Source #

Arguments

:: WindowClass self |
=> self |
-> WindowEdge | `edge` - position of the resize control
-> MouseButton | `button` - mouse button that initiated the drag
-> Int | `rootX` - X position where the user clicked to initiate the drag, in root window coordinates
-> Int | `rootY` - Y position where the user clicked to initiate the drag
-> TimeStamp | `timestamp` - timestamp from the click event that initiated the drag
-> IO () |

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 or windowing system. Otherwise, GDK will try to emulate window resizing, potentially not all that well, depending on the windowing system.

windowBeginMoveDrag Source #

Arguments

:: WindowClass self |
=> self |
-> MouseButton | `button` - mouse button that initiated the drag
-> Int | `rootX` - X position where the user clicked to initiate the drag, in root window coordinates
-> Int | `rootY` - Y position where the user clicked to initiate the drag
-> TimeStamp | `timestamp` - timestamp from the click event that initiated the drag
-> IO () |

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 or windowing system. Otherwise, GDK will try to emulate window movement, potentially not all that well, depending on the windowing system.

windowSetTypeHint Source #

Arguments

:: WindowClass self |
=> self |
-> WindowTypeHint | `hint` - the window type
-> IO () |

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.

This function should be called before the window becomes visible.

windowGetTypeHint Source #

Arguments

:: WindowClass self |
=> self |
-> IO WindowTypeHint | returns the type hint for `window`.

Gets the type hint for this window. See `windowSetTypeHint`.

windowGetIcon Source #

Arguments

:: WindowClass self |
=> self |
-> IO (Maybe Pixbuf) | returns icon for window, or `Nothing` if none was set

Gets the value set by `windowSetIcon` (or if you've called `windowSetIconList`, gets the first icon in the icon list).

windowGetPosition Source #

Arguments

:: WindowClass self |
=> self |
-> IO (Int, Int) | `(rootX, rootY)` - X and Y coordinate of gravity-determined reference point

This function returns the position you need to pass to `windowMove` to keep `window` in its current position. This means that the meaning of the returned value varies with window gravity. See `windowMove` for more details.

If you haven't changed the window gravity, its gravity will be `GravityNorthWest`. This means that `windowGetPosition` gets the position of the top-left corner of the window manager frame for the window. `windowMove` sets the position of this same top-left corner.

Moreover, nearly all window managers are historically broken with respect to their handling of window gravity. So moving a window to its current position as returned by `windowGetPosition` tends to result in moving the window slightly. Window managers are slowly getting better over time.

If a window has gravity `GravityStatic` the window manager frame is not relevant, and thus `windowGetPosition` will always produce accurate results. However you can't use static gravity to do things like place a window in a corner of the screen, because static gravity ignores the window manager decorations.

If you are saving and restoring your application's window positions, you should know that it's impossible for applications to do this without getting it somewhat wrong because applications do not have sufficient knowledge of window manager state. The Correct Mechanism is to support the session management protocol (see the "GnomeClient" object in the GNOME libraries for example) and allow the window manager to save your window sizes and positions.

windowGetSize Source #

Arguments

:: WindowClass self |
=> self |

-> IO (Int, Int)

    (width, height)

Obtains the current size of the window. If the window is not onscreen, it returns the size Gtk+ will suggest to the window manager for the initial window size (but this is not reliably the same as the size the window manager will actually select). The size obtained by `windowGetSize` is the last size received in a `EventConfigure`, that is, Gtk+ uses its locally-stored size, rather than querying the X server for the size. As a result, if you call `windowResize` then immediately call `windowGetSize`, the size won't have taken effect yet. After the window manager processes the resize request, Gtk+ receives notification that the size has changed via a configure event, and the size of the window gets updated.

Note 1: Nearly any use of this function creates a race condition, because the size of the window may change between the time that you get the size and the time that you perform some action assuming that size is the current size. To avoid race conditions, connect to "configure_event" on the window and adjust your size-dependent state to match the size delivered in the `EventConfigure`.

Note 2: The returned size does not include the size of the window manager decorations (aka the window frame or border). Those are not drawn by Gtk+ and Gtk+ has no reliable method of determining their size.

Note 3: If you are getting a window size in order to position the window onscreen, there may be a better way. The preferred way is to simply set the window's semantic type with `windowSetTypeHint`, 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 things rather than doing it yourself, because all apps will behave consistently and according to user prefs if the window manager handles it. Also, the window manager can take the size of the window decorations/border into account, while your application cannot.

In any case, if you insist on application-specified window positioning, there's still a better way than doing it yourself - `windowSetPosition` will frequently handle the details for you.

windowMove Source #

Arguments

:: WindowClass self |
=> self |
-> Int | `x` - X coordinate to move window to
-> Int | `y` - Y coordinate to move window to
-> IO () |

Asks the window manager 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.

Note: the position is the position of the gravity-determined reference point for the window. The gravity determines two things: first, the location of the reference point in root window coordinates; and second, which point on the window is positioned at the reference point.

By default the gravity is `GravityNorthWest`, so the reference point is simply the `x`, `y` supplied to `windowMove`. The top-left corner of the window decorations (aka window frame or border) will be placed at `x`, `y`. Therefore, to position a window at the top left of the screen, you want to use the default gravity (which is `GravityNorthWest`) and move the window to 0,0.

To position a window at the bottom right corner of the screen, you would set `GravitySouthEast`, which means that the reference point is at `x` + the window width and `y` + the window height, and the bottom-right corner of the window border will be placed at that reference point. So, to place a window in the bottom right corner you would first set gravity to south east, then write: `gtk_window_move (window, gdk_screen_width() - window_width, gdk_screen_height() - window_height)`.

The Extended Window Manager Hints specification at http://www.freedesktop.org/Standards/wm-spec has a nice table of gravities in the "implementation notes" section.

The `windowGetPosition` documentation may also be relevant.

windowParseGeometry :: (WindowClass self, GlibString string) => self -> string -> IO Bool Source #

Parses a standard X Window System geometry string - see the manual page for X (type 'man X') for details on this. `windowParseGeometry` does work on all GTK+ ports including Win32 but is primarily intended for an X environment.

If either a size or a position can be extracted from the geometry string, `windowParseGeometry` returns `True` and calls gtk_window_set_default_size() andor gtk_window_move() to resizemove the window.

If `windowParseGeometry` returns `True`, it will also set the `HintUserPos` andor `HintUserSize` hints indicating to the window manager that the sizeposition of the window was user-specified This causes most window managers to honor the geometry.

Note that for `windowParseGeometry` to work as expected, it has to be called when the window has its "final" size, i.e. after calling `widgetShowAll` on the contents and `windowSetGeometryHints` on the window.

windowReshowWithInitialSize :: WindowClass self => self -> IO () Source #

Hides window, then reshows it, resetting the default size and position of the window. Used by GUI builders only.

windowResize Source #

Arguments

:: WindowClass self |
=> self |
-> Int | `width` - width in pixels to resize the window to
-> Int | `height` - height in pixels to resize the window to
-> IO () |

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.

windowSetIconFromFile Source #

Arguments

:: (WindowClass self, GlibFilePath fp) |
=> self |
-> fp | `filename` - location of icon file
-> IO () |

Sets the icon for `window`.

This function is equivalent to calling `windowSetIcon` with a pixbuf created by loading the image from `filename`.

This may throw an exception if the file cannot be loaded.

- Available since Gtk+ version 2.2

windowSetAutoStartupNotification Source #

Arguments

:: Bool | `setting` - `True` to automatically do startup notification
-> IO () |

By default, after showing the first `Window` for each `Screen`, Gtk+ calls `screenNotifyStartupComplete`. 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.

- Available since Gtk+ version 2.2

windowPresentWithTime Source #

Arguments

:: WindowClass self |
=> self |
-> TimeStamp | `timestamp` - the timestamp of the user interaction (typically a button or key press event) which triggered this call
-> IO () |

Presents a window to the user in response to a user interaction. If you need to present a window without a timestamp, use `windowPresent`. See `windowPresent` for details.

- Available since Gtk+ version 2.8

windowSetGeometryHints Source #

Arguments

:: (WindowClass self, WidgetClass widget) |
=> self | `window` - the top level window
-> Maybe widget | `geometryWidget` - optional a widget the geometry hints will be applied to rather than directly to the top level window
-> Maybe (Int, Int) | `(minWidth, minHeight)` - minimum width and height of window (or -1 to use requisition)
-> Maybe (Int, Int) | `(maxWidth, maxHeight)` - maximum width and height of window (or -1 to use requisition)
-> Maybe (Int, Int) | `(baseWidth, baseHeight)` - the allowed window widths are `base_width + width_inc * N` for any int `N`. Similarly, the allowed window widths are `base_height + height_inc * N` for any int `N`. For either the base width or height -1 is allowed as described above.
-> Maybe (Int, Int) | `(widthInc, heightInc)` - width and height resize increment
-> Maybe (Double, Double) | `(minAspect, maxAspect)` - minimum and maximum width/height ratio
-> IO () |

This function sets up hints about how a window can be resized by the user. You can set a minimum and maximum size, the allowed resize increments (e.g. for xterm, you can only resize by the size of a character) and aspect ratios.

If you set a geometry widget, the hints will apply to the geometry widget instead of directly to the toplevel window. Of course since the geometry widget is a child widget of the top level window, constraining the sizing behaviour of the widget will have a knock-on effect on the sizing of the toplevel window.

The `minWidth`/`minHeight`/`maxWidth`/`maxHeight` fields may be set to `-1`, to use the size request of the window or geometry widget. If the minimum size hint is not provided, Gtk+ will use the size requisition of the window (or the geometry widget if it set) as the minimum size. The base size is treated similarly.

The canonical use-case for `windowSetGeometryHints` is to get a terminal widget to resize properly. Here, the terminal text area should be the geometry widget. Gtk+ will then automatically set the base size of the terminal window to the size of other widgets in the terminal window, such as the menubar and scrollbar. Then, the `widthInc` and `heightInc` values should be set to the size of one character in the terminal. Finally, the base size should be set to the size of one character. The net effect is that the minimum size of the terminal will have a 1x1 character terminal area, and only terminal sizes on the "character grid" will be allowed.

The other useful settings are `minAspect` and `maxAspect`. These specify a width/height ratio as a floating point number. If a geometry widget is set, the aspect applies to the geometry widget rather than the entire window. The most common use of these hints is probably to set `minAspect` and `maxAspect` to the same value, thus forcing the window to keep a constant aspect ratio.

windowGetGroup Source #

Arguments

:: WindowClass self |
=> Maybe self |

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.

windowIconList :: WindowClass self => Attr self [Pixbuf] Source #

Sets up the icon representing a `Window`. 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.

By passing several sizes, you may improve the final image quality of the icon, by reducing or eliminating automatic image scaling.

Recommended sizes to provide: 16x16, 32x32, 48x48 at minimum, and larger images (64x64, 128x128) if you have them.

See also `windowSetDefaultIconList` to set the icon for all windows in your application in one go.

Note that transient windows (those who have been set transient for another window using `windowSetTransientFor`) will inherit their icon from their transient parent. So there's no need to explicitly set the icon on transient windows.
