Class
GtkWindow
Description [src]
class Gtk.Window : Gtk.Bin
implements Atk.ImplementorIface, Gtk.Buildable {
priv: GtkWindowPrivate*
}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 GtkBuildable 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().
It also supports the <initial-focus> element, whose name property names
the widget to receive the focus when the window is mapped.
An example of a UI definition fragment with accel groups:
<object class="GtkWindow">
<accel-groups>
<group name="accelgroup1"/>
</accel-groups>
<initial-focus name="thunderclap"/>
</object>
...
<object class="GtkAccelGroup" id="accelgroup1"/>
The GtkWindow implementation of the GtkBuildable interface supports
setting a child as the titlebar by specifying “titlebar” as the “type”
attribute of a <child> element.
CSS nodes
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.
Constructors
gtk_window_new
Creates a new GtkWindow, which is a toplevel window that can
contain other widgets. Nearly always, the type of the window should
be #GTK_WINDOW_TOPLEVEL. If you’re implementing something like a
popup menu from scratch (which is a bad idea, just use GtkMenu),
you might use #GTK_WINDOW_POPUP. #GTK_WINDOW_POPUP is not for
dialogs, though in some other toolkits dialogs are called “popups”.
In GTK+, #GTK_WINDOW_POPUP means a pop-up menu or pop-up tooltip.
On X11, popup windows are not controlled by the
[window manager][gtk-X11-arch].
Functions
gtk_window_get_default_icon_list
Gets the value set by gtk_window_set_default_icon_list(). The list is a copy and should be freed with g_list_free(), but the pixbufs in the list have not had their reference count incremented.
gtk_window_get_default_icon_name
Returns the fallback icon name for windows that has been set with gtk_window_set_default_icon_name(). The returned string is owned by GTK+ and should not be modified. It is only valid until the next call to gtk_window_set_default_icon_name().
since: 2.16
gtk_window_list_toplevels
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.
gtk_window_set_auto_startup_notification
By default, after showing the first GtkWindow, GTK+ calls
gdk_notify_startup_complete(). Call this function to disable
the automatic startup notification. You might do this if your
first window is a splash screen, and you want to delay notification
until after your real main window has been shown, for example.
since: 2.2
gtk_window_set_default_icon
Sets an icon to be used as fallback for windows that haven’t
had gtk_window_set_icon() called on them from a pixbuf.
since: 2.4
gtk_window_set_default_icon_from_file
Sets an icon to be used as fallback for windows that haven’t
had gtk_window_set_icon_list() called on them from a file
on disk. Warns on failure if err is NULL.
since: 2.2
gtk_window_set_default_icon_list
Sets an icon list to be used as fallback for windows that haven’t
had gtk_window_set_icon_list() called on them to set up a
window-specific icon list. This function allows you to set up the
icon for all windows in your app at once.
gtk_window_set_default_icon_name
Sets an icon to be used as fallback for windows that haven’t
had gtk_window_set_icon_list() called on them from a named
themed icon, see gtk_window_set_icon_name().
since: 2.6
gtk_window_set_interactive_debugging
Opens or closes the [interactive debugger][interactive-debugging], which offers access to the widget hierarchy of the application and to useful debugging tools.
since: 3.14
Instance methods
gtk_window_activate_default
Activates the default widget for the window, unless the current focused widget has been configured to receive the default action (see gtk_widget_set_receives_default()), in which case the focused widget is activated.
gtk_window_activate_key
Activates mnemonics and accelerators for this GtkWindow. This is normally
called by the default ::key_press_event handler for toplevel windows,
however in some cases it may be useful to call this directly when
overriding the standard key handling for a toplevel window.
since: 2.4
gtk_window_add_accel_group
Associate accel_group with window, such that calling
gtk_accel_groups_activate() on window will activate accelerators
in accel_group.
gtk_window_begin_move_drag
Starts moving a window. This function is used if an application has window movement grips. When GDK can support it, the window movement will be done using the standard mechanism for the [window manager][gtk-X11-arch] or windowing system. Otherwise, GDK will try to emulate window movement, potentially not all that well, depending on the windowing system.
gtk_window_begin_resize_drag
Starts resizing a window. This function is used if an application has window resizing controls. When GDK can support it, the resize will be done using the standard mechanism for the [window manager][gtk-X11-arch] or windowing system. Otherwise, GDK will try to emulate window resizing, potentially not all that well, depending on the windowing system.
gtk_window_close
Requests that the window is closed, similar to what happens when a window manager close button is clicked.
since: 3.10
gtk_window_deiconify
Asks to deiconify (i.e. unminimize) the specified window. Note
that you shouldn’t assume the window is definitely deiconified
afterward, because other entities (e.g. the user or
[window manager][gtk-X11-arch])) could iconify it
again before your code which assumes deiconification gets to run.
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. But normally the window will end up fullscreen. Just
don’t write code that crashes if not.
since: 2.2
gtk_window_fullscreen_on_monitor
Asks to place window in the fullscreen state. Note that you shouldn’t assume
the window is definitely full screen afterward.
since: 3.18
gtk_window_get_attached_to
Fetches the attach widget for this window. See gtk_window_set_attached_to().
since: 3.4
gtk_window_get_decorated
Returns whether the window has been set to have decorations such as a title bar via gtk_window_set_decorated().
gtk_window_get_default_size
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.
gtk_window_get_default_widget
Returns the default widget for window. See
gtk_window_set_default() for more details.
since: 2.14
gtk_window_get_deletable
Returns whether the window has been set to have a close button via gtk_window_set_deletable().
since: 2.10
gtk_window_get_destroy_with_parent
Returns whether the window will be destroyed with its transient parent. See gtk_window_set_destroy_with_parent ().
gtk_window_get_focus
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.
gtk_window_get_group
Returns the group for window or the default group, if
window is NULL or if window does not have an explicit
window group.
since: 2.10
gtk_window_get_has_resize_grip
Determines whether the window may have a resize grip.
deprecated: 3.14 since: 3.0
gtk_window_get_hide_titlebar_when_maximized
Returns whether the window has requested to have its titlebar hidden when maximized. See gtk_window_set_hide_titlebar_when_maximized ().
since: 3.4
gtk_window_get_icon
Gets the value set by gtk_window_set_icon() (or if you’ve
called gtk_window_set_icon_list(), gets the first icon in
the icon list).
gtk_window_get_icon_list
Retrieves the list of icons set by gtk_window_set_icon_list(). The list is copied, but the reference count on each member won’t be incremented.
gtk_window_get_icon_name
Returns the name of the themed icon for the window, see gtk_window_set_icon_name().
since: 2.6
gtk_window_get_mnemonic_modifier
Returns the mnemonic modifier for this window. See gtk_window_set_mnemonic_modifier().
gtk_window_get_mnemonics_visible
Gets the value of the GtkWindow:mnemonics-visible property.
since: 2.20
gtk_window_get_opacity
Fetches the requested opacity for this window. See gtk_window_set_opacity().
deprecated: 3.8 since: 2.12
gtk_window_get_position
This function returns the position you need to pass to
gtk_window_move() to keep window in its current position.
This means that the meaning of the returned value varies with
window gravity. See gtk_window_move() for more details.
gtk_window_get_resize_grip_area
If a window has a resize grip, this will retrieve the grip
position, width and height into the specified GdkRectangle.
deprecated: 3.14 since: 3.0
gtk_window_get_role
Returns the role of the window. See gtk_window_set_role() for
further explanation.
gtk_window_get_skip_taskbar_hint
Gets the value set by gtk_window_set_skip_taskbar_hint().
since: 2.2
gtk_window_get_titlebar
Returns the custom titlebar that has been set with gtk_window_set_titlebar().
since: 3.16
gtk_window_get_transient_for
Fetches the transient parent for this window. See gtk_window_set_transient_for().
gtk_window_has_toplevel_focus
Returns whether the input focus is within this GtkWindow.
For real toplevel windows, this is identical to gtk_window_is_active(),
but for embedded windows, like GtkPlug, the results will differ.
since: 2.4
gtk_window_iconify
Asks to iconify (i.e. minimize) the specified window. Note that
you shouldn’t assume the window is definitely iconified afterward,
because other entities (e.g. the user or
[window manager][gtk-X11-arch]) could deiconify it
again, or there may not be a window manager in which case
iconification isn’t possible, etc. But normally the window will end
up iconified. Just don’t write code that crashes if not.
gtk_window_is_active
Returns whether the window is part of the current active toplevel.
(That is, the toplevel window receiving keystrokes.)
The return value is TRUE if the window is active toplevel
itself, but also if it is, say, a GtkPlug embedded in the active toplevel.
You might use this function if you wanted to draw a widget
differently in an active window from a widget in an inactive window.
See gtk_window_has_toplevel_focus().
since: 2.4
gtk_window_maximize
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.
gtk_window_move
Asks the [window manager][gtk-X11-arch] to move
window to the given position. Window managers are free to ignore
this; most window managers ignore requests for initial window
positions (instead using a user-defined placement algorithm) and
honor requests after the window has already been shown.
gtk_window_parse_geometry
Parses a standard X Window System geometry string - see the
manual page for X (type “man X”) for details on this.
gtk_window_parse_geometry() does work on all GTK+ ports
including Win32 but is primarily intended for an X environment.
deprecated: 3.20
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.
gtk_window_present_with_time
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.
since: 2.8
gtk_window_propagate_key_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 ::key_press_event and
::key_release_event handlers for toplevel windows,
however in some cases it may be useful to call this directly when
overriding the standard key handling for a toplevel window.
since: 2.4
gtk_window_reshow_with_initial_size
Hides window, then reshows it, resetting the
default size and position of the window. Used
by GUI builders only.
deprecated: 3.10
gtk_window_resize
Resizes the window as if the user had done so, obeying geometry
constraints. The default geometry constraint is that windows may
not be smaller than their size request; to override this
constraint, call gtk_widget_set_size_request() to set the window’s
request to a smaller value.
gtk_window_resize_grip_is_visible
Determines whether a resize grip is visible for the specified window.
deprecated: 3.14 since: 3.0
gtk_window_resize_to_geometry
Like gtk_window_resize(), but width and height are interpreted
in terms of the base size and increment set with gtk_window_set_geometry_hints.
deprecated: 3.20 since: 3.0
gtk_window_set_accept_focus
Windows may set a hint asking the desktop environment not to receive the input focus. This function sets this hint.
since: 2.4
gtk_window_set_attached_to
Marks window as attached to attach_widget. This creates a logical binding
between the window and the widget it belongs to, which is used by GTK+ to
propagate information such as styling or accessibility to window as if it
was a children of attach_widget.
since: 3.4
gtk_window_set_decorated
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().
gtk_window_set_default
The default widget is the widget that’s activated when the user
presses Enter in a dialog (for example). This function sets or
unsets the default widget for a GtkWindow. When setting (rather
than unsetting) the default widget it’s generally easier to call
gtk_widget_grab_default() on the widget. Before making a widget
the default widget, you must call gtk_widget_set_can_default() on
the widget you’d like to make the default.
gtk_window_set_default_geometry
Like gtk_window_set_default_size(), but width and height are interpreted
in terms of the base size and increment set with gtk_window_set_geometry_hints.
deprecated: 3.20 since: 3.0
gtk_window_set_default_size
Sets the default size of a window. If the window’s “natural” size (its size request) is larger than the default, the default will be ignored. More generally, if the default size does not obey the geometry hints for the window (gtk_window_set_geometry_hints() can be used to set these explicitly), the default size will be clamped to the nearest permitted size.
gtk_window_set_deletable
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().
since: 2.10
gtk_window_set_destroy_with_parent
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.
gtk_window_set_focus
If focus is not the current focus widget, and is focusable, sets
it as the focus widget for the window. If focus is NULL, unsets
the focus widget for this window. To set the focus to a particular
widget in the toplevel, it is usually more convenient to use
gtk_widget_grab_focus() instead of this function.
gtk_window_set_focus_on_map
Windows may set a hint asking the desktop environment not to receive the input focus when the window is mapped. This function sets this hint.
since: 2.6
gtk_window_set_geometry_hints
This function sets up hints about how a window can be resized by
the user. You can set a minimum and maximum size; allowed resize
increments (e.g. for xterm, you can only resize by the size of a
character); aspect ratios; and more. See the GdkGeometry struct.
gtk_window_set_gravity
Window gravity defines the meaning of coordinates passed to
gtk_window_move(). See gtk_window_move() and GdkGravity for
more details.
gtk_window_set_has_resize_grip
Sets whether window has a corner resize grip.
deprecated: 3.14 since: 3.0
gtk_window_set_has_user_ref_count
Tells GTK+ whether to drop its extra reference to the window
when gtk_widget_destroy() is called.
since: 3.0
gtk_window_set_hide_titlebar_when_maximized
If setting is TRUE, then window will request that it’s titlebar
should be hidden when maximized.
This is useful for windows that don’t convey any information other
than the application name in the titlebar, to put the available
screen space to better use. If the underlying window system does not
support the request, the setting will not have any effect.
since: 3.4
gtk_window_set_icon
Sets up the icon representing a GtkWindow. This icon is used when
the window is minimized (also known as iconified). Some window
managers or desktop environments may also place it in the window
frame, or display it in other contexts. On others, the icon is not
used at all, so your mileage may vary.
gtk_window_set_icon_list
Sets up the icon representing a GtkWindow. The icon is used when
the window is minimized (also known as iconified). Some window
managers or desktop environments may also place it in the window
frame, or display it in other contexts. On others, the icon is not
used at all, so your mileage may vary.
gtk_window_set_icon_name
Sets the icon for the window from a named themed icon.
See the docs for GtkIconTheme for more details.
On some platforms, the window icon is not used at all.
since: 2.6
gtk_window_set_keep_above
Asks to keep window above, so that it stays on top. Note that
you shouldn’t assume the window is definitely above afterward,
because other entities (e.g. the user or
[window manager][gtk-X11-arch]) could not keep it above,
and not all window managers support keeping windows above. But
normally the window will end kept above. Just don’t write code
that crashes if not.
since: 2.4
gtk_window_set_keep_below
Asks to keep window below, so that it stays in bottom. Note that
you shouldn’t assume the window is definitely below afterward,
because other entities (e.g. the user or
[window manager][gtk-X11-arch]) could not keep it below,
and not all window managers support putting windows below. But
normally the window will be kept below. Just don’t write code
that crashes if not.
since: 2.4
gtk_window_set_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
gtk_window_set_transient_for() to make the dialog transient for the
parent; most [window managers][gtk-X11-arch]
will then disallow lowering the dialog below the parent.
gtk_window_set_opacity
Request the windowing system to make window partially transparent,
with opacity 0 being fully transparent and 1 fully opaque. (Values
of the opacity parameter are clamped to the [0,1] range.) On X11
this has any effect only on X screens with a compositing manager
running. See gtk_widget_is_composited(). On Windows it should work always.
deprecated: 3.8 since: 2.12
gtk_window_set_position
Sets a position constraint for this window. If the old or new
constraint is GTK_WIN_POS_CENTER_ALWAYS, this will also cause
the window to be repositioned to satisfy the new constraint.
gtk_window_set_resizable
Sets whether the user can resize a window. Windows are user resizable by default.
gtk_window_set_screen
Sets the GdkScreen where the window is displayed; if
the window is already mapped, it will be unmapped, and
then remapped on the new screen.
since: 2.2
gtk_window_set_skip_pager_hint
Windows may set a hint asking the desktop environment not to display the window in the pager. This function sets this hint. (A “pager” is any desktop navigation tool such as a workspace switcher that displays a thumbnail representation of the windows on the screen.).
since: 2.2
gtk_window_set_skip_taskbar_hint
Windows may set a hint asking the desktop environment not to display the window in the task bar. This function sets this hint.
since: 2.2
gtk_window_set_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 GdkWindow. Normally, startup identifier is managed
automatically and you should only use this function in special cases
like transferring focus from other processes. You should use this
function before calling gtk_window_present() or any equivalent
function generating a window map event.
since: 2.12
gtk_window_set_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][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.
gtk_window_set_transient_for
Dialog windows should be set transient for the main application
window they were spawned from. This allows
[window managers][gtk-X11-arch] to e.g. keep the
dialog on top of the main window, or center the dialog over the
main window. gtk_dialog_new_with_buttons() and other convenience
functions in GTK+ will sometimes call
gtk_window_set_transient_for() on your behalf.
gtk_window_set_type_hint
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.
gtk_window_set_urgency_hint
Windows may set a hint asking the desktop environment to draw the users attention to the window. This function sets this hint.
since: 2.8
gtk_window_set_wmclass
Don’t use this function. It sets the X Window System “class” and
“name” hints for a window. According to the ICCCM, you should
always set these to the same value for all windows in an
application, and GTK+ sets them to that value by default, so calling
this function is sort of pointless. However, you may want to call
gtk_window_set_role() on each window in your application, for the
benefit of the session manager. Setting the role allows the window
manager to restore window positions when loading a saved session.
deprecated: 3.22
gtk_window_stick
Asks to stick window, which means that it will appear on all user
desktops. Note that you shouldn’t assume the window is definitely
stuck afterward, because other entities (e.g. the user or
[window manager][gtk-X11-arch] could unstick it
again, and some window managers do not support sticking
windows. But normally the window will end up stuck. Just don’t
write code that crashes if not.
gtk_window_unfullscreen
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.
since: 2.2
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. But normally the window will
end up unmaximized. Just don’t write code that crashes if not.
gtk_window_unstick
Asks to unstick window, which means that it will appear on only
one of the user’s desktops. Note that you shouldn’t assume the
window is definitely unstuck afterward, because other entities
(e.g. the user or [window manager][gtk-X11-arch]) could
stick it again. But normally the window will
end up unstuck. Just don’t write code that crashes if not.

Signals
Gtk.Window::activate-default
The ::activate-default signal is a
[keybinding signal][GtkBindingSignal]
which gets emitted when the user activates the default widget
of window.
Gtk.Window::activate-focus
The ::activate-focus signal is a
[keybinding signal][GtkBindingSignal]
which gets emitted when the user activates the currently
focused widget of window.
Gtk.Window::enable-debugging
The ::enable-debugging signal is a [keybinding signal][GtkBindingSignal]
which gets emitted when the user enables or disables interactive
debugging. When toggle is TRUE, interactive debugging is toggled
on or off, when it is FALSE, the debugger will be pointed at the
widget under the pointer.
Gtk.Window::keys-changed
The ::keys-changed signal gets emitted when the set of accelerators
or mnemonics that are associated with window changes.
Gtk.Window::set-focus
This signal is emitted whenever the currently focused widget in this window changes.
since: 2.24
Signals inherited from GtkContainer (4)
GtkContainer::add
GtkContainer::check-resize
GtkContainer::remove
GtkContainer::set-focus-child
Signals inherited from GtkWidget (69)
GtkWidget::accel-closures-changed
GtkWidget::button-press-event
The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.
GtkWidget::button-release-event
The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.
GtkWidget::can-activate-accel
Determines whether an accelerator that activates the signal
identified by signal_id can currently be activated.
This signal is present to allow applications and derived
widgets to override the default GtkWidget handling
for determining whether an accelerator can be activated.
GtkWidget::child-notify
The ::child-notify signal is emitted for each [child property][child-properties] that has changed on an object. The signal’s detail holds the property name.
GtkWidget::composited-changed
The ::composited-changed signal is emitted when the composited
status of widgets screen changes.
See gdk_screen_is_composited().
deprecated: 3.22
GtkWidget::configure-event
The ::configure-event signal will be emitted when the size, position or
stacking of the widget‘s window has changed.
GtkWidget::damage-event
Emitted when a redirected window belonging to widget gets drawn into.
The region/area members of the event shows what area of the redirected
drawable was drawn into.
since: 2.14
GtkWidget::delete-event
The ::delete-event signal is emitted if a user requests that
a toplevel window is closed. The default handler for this signal
destroys the window. Connecting gtk_widget_hide_on_delete() to
this signal will cause the window to be hidden instead, so that
it can later be shown again without reconstructing it.
GtkWidget::destroy
Signals that all holders of a reference to the widget should release the reference that they hold. May result in finalization of the widget if all references are released.
GtkWidget::destroy-event
The ::destroy-event signal is emitted when a GdkWindow is destroyed.
You rarely get this signal, because most widgets disconnect themselves
from their window before they destroy it, so no widget owns the
window at destroy time.
GtkWidget::direction-changed
The ::direction-changed signal is emitted when the text direction of a widget changes.
GtkWidget::drag-begin
The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with e.g. gtk_drag_source_set_icon_pixbuf().
GtkWidget::drag-data-delete
The ::drag-data-delete signal is emitted on the drag source when a drag
with the action GDK_ACTION_MOVE is successfully completed. The signal
handler is responsible for deleting the data that has been dropped. What
“delete” means depends on the context of the drag operation.
GtkWidget::drag-data-get
The ::drag-data-get signal is emitted on the drag source when the drop
site requests the data which is dragged. It is the responsibility of
the signal handler to fill data with the data in the format which
is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text().
GtkWidget::drag-data-received
The ::drag-data-received signal is emitted on the drop site when the
dragged data has been received. If the data was received in order to
determine whether the drop will be accepted, the handler is expected
to call gdk_drag_status() and not finish the drag.
If the data was received in response to a GtkWidget::drag-drop signal
(and this is the last target to be received), the handler for this
signal is expected to process the received data and then call
gtk_drag_finish(), setting the success parameter depending on
whether the data was processed successfully.
GtkWidget::drag-drop
The ::drag-drop signal is emitted on the drop site when the user drops
the data onto the widget. The signal handler must determine whether
the cursor position is in a drop zone or not. If it is not in a drop
zone, it returns FALSE and no further processing is necessary.
Otherwise, the handler returns TRUE. In this case, the handler must
ensure that gtk_drag_finish() is called to let the source know that
the drop is done. The call to gtk_drag_finish() can be done either
directly or in a GtkWidget::drag-data-received handler which gets
triggered by calling gtk_drag_get_data() to receive the data for one
or more of the supported targets.
GtkWidget::drag-end
The ::drag-end signal is emitted on the drag source when a drag is
finished. A typical reason to connect to this signal is to undo
things done in GtkWidget::drag-begin.
GtkWidget::drag-failed
The ::drag-failed signal is emitted on the drag source when a drag has
failed. The signal handler may hook custom code to handle a failed DnD
operation based on the type of error, it returns TRUE is the failure has
been already handled (not showing the default “drag operation failed”
animation), otherwise it returns FALSE.
since: 2.12
GtkWidget::drag-leave
The ::drag-leave signal is emitted on the drop site when the cursor
leaves the widget. A typical reason to connect to this signal is to
undo things done in GtkWidget::drag-motion, e.g. undo highlighting
with gtk_drag_unhighlight().
GtkWidget::drag-motion
The ::drag-motion signal is emitted on the drop site when the user
moves the cursor over the widget during a drag. The signal handler
must determine whether the cursor position is in a drop zone or not.
If it is not in a drop zone, it returns FALSE and no further processing
is necessary. Otherwise, the handler returns TRUE. In this case, the
handler is responsible for providing the necessary information for
displaying feedback to the user, by calling gdk_drag_status().
GtkWidget::draw
This signal is emitted when a widget is supposed to render itself.
The widget‘s top left corner must be painted at the origin of
the passed in context and be sized to the values returned by
gtk_widget_get_allocated_width() and gtk_widget_get_allocated_height().
since: 3.0
GtkWidget::enter-notify-event
The ::enter-notify-event will be emitted when the pointer enters
the widget‘s window.
GtkWidget::event
The GTK+ main loop will emit three signals for each GDK event delivered
to a widget: one generic ::event signal, another, more specific,
signal that matches the type of event delivered (e.g.
GtkWidget::key-press-event) and finally a generic
GtkWidget::event-after signal.
GtkWidget::event-after
After the emission of the GtkWidget::event signal and (optionally)
the second more specific signal, ::event-after will be emitted
regardless of the previous two signals handlers return values.
GtkWidget::focus
GtkWidget::focus-in-event
The ::focus-in-event signal will be emitted when the keyboard focus
enters the widget‘s window.
GtkWidget::focus-out-event
The ::focus-out-event signal will be emitted when the keyboard focus
leaves the widget‘s window.
GtkWidget::grab-broken-event
Emitted when a pointer or keyboard grab on a window belonging
to widget gets broken.
since: 2.8
GtkWidget::grab-focus
GtkWidget::grab-notify
The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.
GtkWidget::hide
The ::hide signal is emitted when widget is hidden, for example with gtk_widget_hide().
GtkWidget::hierarchy-changed
The ::hierarchy-changed signal is emitted when the
anchored state of a widget changes. A widget is
“anchored” when its toplevel
ancestor is a GtkWindow. This signal is emitted when
a widget changes from un-anchored to anchored or vice-versa.
GtkWidget::key-press-event
The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.
GtkWidget::key-release-event
The ::key-release-event signal is emitted when a key is released.
GtkWidget::keynav-failed
Gets emitted if keyboard navigation fails.
See gtk_widget_keynav_failed() for details.
since: 2.12
GtkWidget::leave-notify-event
The ::leave-notify-event will be emitted when the pointer leaves
the widget‘s window.
GtkWidget::map
The ::map signal is emitted when widget is going to be mapped, that is
when the widget is visible (which is controlled with
gtk_widget_set_visible()) and all its parents up to the toplevel widget
are also visible. Once the map has occurred, GtkWidget::map-event will
be emitted.
GtkWidget::map-event
The ::map-event signal will be emitted when the widget‘s window is
mapped. A window is mapped when it becomes visible on the screen.
GtkWidget::mnemonic-activate
The default handler for this signal activates widget if group_cycling
is FALSE, or just makes widget grab focus if group_cycling is TRUE.
GtkWidget::motion-notify-event
The ::motion-notify-event signal is emitted when the pointer moves
over the widget’s GdkWindow.
GtkWidget::move-focus
GtkWidget::parent-set
The ::parent-set signal is emitted when a new parent has been set on a widget.
GtkWidget::popup-menu
This signal gets emitted whenever a widget should pop up a context
menu. This usually happens through the standard key binding mechanism;
by pressing a certain key while a widget is focused, the user can cause
the widget to pop up a menu. For example, the GtkEntry widget creates
a menu with clipboard commands. See the
[Popup Menu Migration Checklist][checklist-popup-menu]
for an example of how to use this signal.
GtkWidget::property-notify-event
The ::property-notify-event signal will be emitted when a property on
the widget‘s window has been changed or deleted.
GtkWidget::proximity-in-event
To receive this signal the GdkWindow associated to the widget needs
to enable the #GDK_PROXIMITY_IN_MASK mask.
GtkWidget::proximity-out-event
To receive this signal the GdkWindow associated to the widget needs
to enable the #GDK_PROXIMITY_OUT_MASK mask.
GtkWidget::query-tooltip
Emitted when GtkWidget:has-tooltip is TRUE and the hover timeout
has expired with the cursor hovering “above” widget; or emitted when widget got
focus in keyboard mode.
since: 2.12
GtkWidget::realize
The ::realize signal is emitted when widget is associated with a
GdkWindow, which means that gtk_widget_realize() has been called or the
widget has been mapped (that is, it is going to be drawn).
GtkWidget::screen-changed
The ::screen-changed signal gets emitted when the screen of a widget has changed.
GtkWidget::scroll-event
The ::scroll-event signal is emitted when a button in the 4 to 7 range is pressed. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.
GtkWidget::selection-clear-event
The ::selection-clear-event signal will be emitted when the
the widget‘s window has lost ownership of a selection.
GtkWidget::selection-get
GtkWidget::selection-notify-event
GtkWidget::selection-received
GtkWidget::selection-request-event
The ::selection-request-event signal will be emitted when
another client requests ownership of the selection owned by
the widget‘s window.
GtkWidget::show
The ::show signal is emitted when widget is shown, for example with gtk_widget_show().
GtkWidget::show-help
GtkWidget::size-allocate
GtkWidget::state-changed
The ::state-changed signal is emitted when the widget state changes. See gtk_widget_get_state().
deprecated: 3.0
GtkWidget::state-flags-changed
The ::state-flags-changed signal is emitted when the widget state changes, see gtk_widget_get_state_flags().
since: 3.0
GtkWidget::style-set
The ::style-set signal is emitted when a new style has been set
on a widget. Note that style-modifying functions like
gtk_widget_modify_base() also cause this signal to be emitted.
deprecated: 3.0
GtkWidget::style-updated
The ::style-updated signal is a convenience signal that is emitted when the
GtkStyleContext::changed signal is emitted on the widget‘s associated
GtkStyleContext as returned by gtk_widget_get_style_context().
since: 3.0
GtkWidget::touch-event
GtkWidget::unmap
The ::unmap signal is emitted when widget is going to be unmapped, which
means that either it or any of its parents up to the toplevel widget have
been set as hidden.
GtkWidget::unmap-event
The ::unmap-event signal will be emitted when the widget‘s window is
unmapped. A window is unmapped when it becomes invisible on the screen.
GtkWidget::unrealize
The ::unrealize signal is emitted when the GdkWindow associated with
widget is destroyed, which means that gtk_widget_unrealize() has been
called or the widget has been unmapped (that is, it is going to be hidden).
GtkWidget::visibility-notify-event
The ::visibility-notify-event will be emitted when the widget‘s
window is obscured or unobscured.
deprecated: 3.12
GtkWidget::window-state-event
The ::window-state-event will be emitted when the state of the
toplevel window associated to the widget changes.
