The accel group holding accelerators for the menu.
An accel path used to conveniently construct accel paths of child items.
The index of the currently selected menu item, or -1 if no menu item is selected.
Positioning hints for aligning the menu relative to a rectangle.
These hints determine how the menu should be positioned in the case that the menu would fall off-screen if placed in its ideal position.
For example, %GDK_ANCHOR_FLIP_Y will replace %GDK_GRAVITY_NORTH_WEST with %GDK_GRAVITY_SOUTH_WEST and vice versa if the menu extends beyond the bottom edge of the monitor.
See gtk_menu_popup_at_rect (), gtk_menu_popup_at_widget (), gtk_menu_popup_at_pointer (), #GtkMenu:rect-anchor-dx, #GtkMenu:rect-anchor-dy, #GtkMenu:menu-type-hint, and #GtkMenu::popped-up.
The widget the menu is attached to. Setting this property attaches the menu without a #GtkMenuDetachFunc. If you need to use a detacher, use gtk_menu_attach_to_widget() directly.
Whether the widget is double buffered.
Whether to expand in both directions. Setting this sets both #GtkWidget:hexpand and #GtkWidget:vexpand
Whether the widget should grab focus when it is clicked with the mouse.
This property is only relevant for widgets that can take focus.
Before 3.20, several widgets (GtkButton, GtkFileChooserButton, GtkComboBox) implemented this property individually.
How to distribute horizontal space if widget gets extra space, see #GtkAlign
Enables or disables the emission of #GtkWidget::query-tooltip on widget.
A value of %TRUE indicates that widget can have a tooltip, in this case
the widget will be queried using #GtkWidget::query-tooltip to determine
whether it will provide a tooltip or not.
Note that setting this property to %TRUE for the first time will change the event masks of the GdkWindows of this widget to include leave-notify and motion-notify events. This cannot and will not be undone when the property is set to %FALSE again.
Whether to expand horizontally. See gtk_widget_set_hexpand().
Whether to use the #GtkWidget:hexpand property. See gtk_widget_get_hexpand_set().
Sets all four sides' margin at once. If read, returns max margin on any side.
Margin on bottom side of widget.
This property adds margin outside of the widget's normal size request, the margin will be added in addition to the size from gtk_widget_set_size_request() for example.
Margin on end of widget, horizontally. This property supports left-to-right and right-to-left text directions.
This property adds margin outside of the widget's normal size request, the margin will be added in addition to the size from gtk_widget_set_size_request() for example.
Margin on left side of widget.
This property adds margin outside of the widget's normal size request, the margin will be added in addition to the size from gtk_widget_set_size_request() for example.
Margin on right side of widget.
This property adds margin outside of the widget's normal size request, the margin will be added in addition to the size from gtk_widget_set_size_request() for example.
Margin on start of widget, horizontally. This property supports left-to-right and right-to-left text directions.
This property adds margin outside of the widget's normal size request, the margin will be added in addition to the size from gtk_widget_set_size_request() for example.
Margin on top side of widget.
This property adds margin outside of the widget's normal size request, the margin will be added in addition to the size from gtk_widget_set_size_request() for example.

The monitor the menu will be popped up on.
The requested opacity of the widget. See gtk_widget_set_opacity() for more details about window opacity.
Before 3.8 this was only available in GtkWindow
Horizontal offset to apply to the menu, i.e. the rectangle or widget anchor.
See gtk_menu_popup_at_rect (), gtk_menu_popup_at_widget (), gtk_menu_popup_at_pointer (), #GtkMenu:anchor-hints, #GtkMenu:rect-anchor-dy, #GtkMenu:menu-type-hint, and #GtkMenu::popped-up.

A boolean that indicates whether the menu reserves space for toggles and icons, regardless of their actual presence.
This property should only be changed from its default value for special-purposes such as tabular menus. Regular menus that are connected to a menu bar or context menus should reserve toggle space for consistency.
The scale factor of the widget. See gtk_widget_get_scale_factor() for more details about widget scaling.
The style of the widget, which contains information about how it will look (colors, etc).
A boolean that determines whether the menu and its submenus grab the keyboard focus. See gtk_menu_shell_set_take_focus() and gtk_menu_shell_get_take_focus().
A boolean that indicates whether the menu is torn-off.
A title that may be displayed by the window manager when this menu is torn-off.
Sets the text of tooltip to be the given string, which is marked up with the [Pango text markup language][PangoMarkupFormat]. Also see gtk_tooltip_set_markup().
This is a convenience property which will take care of getting the tooltip shown if the given string is not %NULL: #GtkWidget:has-tooltip will automatically be set to %TRUE and there will be taken care of #GtkWidget::query-tooltip in the default signal handler.
Note that if both #GtkWidget:tooltip-text and #GtkWidget:tooltip-markup are set, the last one wins.

The widget's window if it is realized, %NULL otherwise.
For widgets that can be “activated” (buttons, menu items, etc.)
this function activates them. Activation is what happens when you
press Enter on a widget during key navigation. If widget isn't
activatable, the function returns %FALSE.
Adds widget to container. Typically used for simple containers
such as #GtkWindow, #GtkFrame, or #GtkButton; for more complicated
layout containers such as #GtkBox or #GtkGrid, this function will
pick default packing parameters that may not be correct. So
consider functions such as gtk_box_pack_start() and
gtk_grid_attach() as an alternative to gtk_container_add() in
those cases. A widget may be added to only one container at a time;
you can’t place the same widget inside two different containers.
Note that some containers, such as #GtkScrolledWindow or #GtkListBox, may add intermediate children between the added widget and the container.
Installs an accelerator for this widget in accel_group that causes
accel_signal to be emitted if the accelerator is activated.
The accel_group needs to be added to the widget’s toplevel via
gtk_window_add_accel_group(), and the signal must be of type %G_SIGNAL_ACTION.
Accelerators added through this function are not user changeable during
runtime. If you want to support accelerators that can be changed by the
user, use gtk_accel_map_add_entry() and gtk_widget_set_accel_path() or
gtk_menu_item_set_accel_path() instead.

[input handling overview][event-masks] for details.
an event mask, see #GdkEventMask
Adds a widget to the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). Note the list of mnemonic labels for the widget is cleared when the widget is destroyed, so the caller must make sure to update its internal state at this point as well, by using a connection to the #GtkWidget::destroy signal or a weak notifier.
Queues an animation frame update and adds a callback to be called before each frame. Until the tick callback is removed, it will be called frequently (usually at the frame rate of the output device or as quickly as the application can be repainted, whichever is slower). For this reason, is most suitable for handling graphics that change every frame or every few frames. The tick callback does not automatically imply a relayout or repaint. If you want a repaint or relayout, and aren’t changing widget properties that would trigger that (for example, changing the text of a #GtkLabel), then you will have to call gtk_widget_queue_resize() or gtk_widget_queue_draw_area() yourself.
gdk_frame_clock_get_frame_time() should generally be used for timing continuous animations and gdk_frame_timings_get_predicted_presentation_time() if you are trying to display isolated frames at particular times.
This is a more convenient alternative to connecting directly to the #GdkFrameClock::update signal of #GdkFrameClock, since you don't have to worry about when a #GdkFrameClock is assigned to a widget.
function to call for updating animations
Adds a new #GtkMenuItem to a (table) menu. The number of “cells” that
an item will occupy is specified by left_attach, right_attach,
top_attach and bottom_attach. These each represent the leftmost,
rightmost, uppermost and lower column and row numbers of the table.
(Columns and rows are indexed from zero).
Note that this function is not related to gtk_menu_detach().

Attaches the menu to the widget and provides a callback function that will be invoked when the menu calls gtk_menu_detach() during its destruction.
If the menu is attached to the widget then it will be destroyed when the widget is destroyed, as if it was a child widget. An attached menu will also move between screens correctly if the widgets moves between screens.

Establishes a binding between a #GtkMenuShell and a #GMenuModel.
The contents of shell are removed and then refilled with menu items
according to model. When model changes, shell is updated.
Calling this function twice on shell with different model will
cause the first binding to be replaced with a binding to the new
model. If model is %NULL then any previous binding is undone and
all children are removed.
with_separators determines if toplevel items (eg: sections) have
separators inserted between them. This is typically desired for
menus but doesn’t make sense for menubars.
If action_namespace is non-%NULL then the effect is as if all
actions mentioned in the model have their names prefixed with the
namespace, plus a dot. For example, if the action “quit” is
mentioned and action_namespace is “app” then the effective action
name is “app.quit”.
This function uses #GtkActionable to define the action name and target values on the created menu items. If you want to use an action group other than “app” and “win”, or if you want to use a #GtkMenuShell outside of a #GtkApplicationWindow, then you will need to attach your own action group to the widget hierarchy using gtk_widget_insert_action_group(). As an example, if you created a group with a “quit” action and inserted it with the name “mygroup” then you would use the action name “mygroup.quit” in your #GMenuModel.
For most cases you are probably better off using gtk_menu_new_from_model() or gtk_menu_bar_new_from_model() or just directly passing the #GMenuModel to gtk_application_set_app_menu() or gtk_application_set_menubar().

Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.
If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
#GBinding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A #GObject can have multiple bindings.

Creates a binding between source_property on source and target_property
on target, allowing you to set the transformation functions to be used by
the binding.

Determines whether an accelerator that activates the signal
identified by signal_id can currently be activated.
This is done by emitting the #GtkWidget::can-activate-accel
signal on widget; if the signal isn’t overridden by a
handler or in a derived widget, then the default check is
that the widget must be sensitive, and the widget and all
its ancestors mapped.
the ID of a signal installed on widget
Cancels the selection within the menu shell.
This function is used by custom widget implementations; if you're writing an app, you’d use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. So you may want to investigate those functions instead.
gtk_widget_child_focus() is called by containers as the user moves
around the window using keyboard shortcuts. direction indicates
what kind of motion is taking place (up, down, left, right, tab
forward, tab backward). gtk_widget_child_focus() emits the
#GtkWidget::focus signal; widgets override the default handler
for this signal in order to implement appropriate focus behavior.
The default ::focus handler for a widget should return %TRUE if
moving in direction left the focus on a focusable location inside
that widget, and %FALSE if moving in direction moved the focus
outside the widget. If returning %TRUE, widgets normally
call gtk_widget_grab_focus() to place the focus accordingly;
if returning %FALSE, they don’t modify the current focus location.

Returns the type of the children supported by the container.
Note that this may return %G_TYPE_NONE to indicate that no more children can be added, e.g. for a #GtkPaned which already has two children.
Same as gtk_widget_path(), but always uses the name of a widget’s type, never uses a custom name set with gtk_widget_set_name().
Computes whether a container should give this widget extra space when possible. Containers should check this, rather than looking at gtk_widget_get_hexpand() or gtk_widget_get_vexpand().
This function already checks whether the widget is visible, so visibility does not need to be checked separately. Non-visible widgets are not expanded.
The computed expand value uses either the expand setting explicitly set on the widget itself, or, if none has been explicitly set, the widget may expand if some of its children do.
expand direction
Creates a new #PangoLayout with the appropriate font map, font description, and base direction for drawing text for this widget.
If you keep a #PangoLayout created in this way around, you need to re-create it when the widget #PangoContext is replaced. This can be tracked by using the #GtkWidget::screen-changed signal on the widget.

Deactivates the menu shell.
Typically this results in the menu shell being erased from the screen.
Deselects the currently selected item from the menu shell, if any.
Destroys a widget.
When a widget is destroyed all references it holds on other objects will be released:
It's expected that all references held on the widget will also
be released; you should connect to the #GtkWidget::destroy signal
if you hold a reference to widget and you wish to remove it when
this function is called. It is not necessary to do so if you are
implementing a #GtkContainer, as you'll be able to use the
#GtkContainerClass.remove() virtual function for that.
It's important to notice that gtk_widget_destroy() will only cause
the widget to be finalized if no additional references, acquired
using g_object_ref(), are held on it. In case additional references
are in place, the widget will be in an "inert" state after calling
this function; widget will still point to valid memory, allowing you
to release the references you hold, but you may not query the widget's
own state.
You should typically call this function on top level widgets, and rarely on child widgets.
See also: gtk_container_remove()
This function sets *widget_pointer to %NULL if widget_pointer !=
%NULL. It’s intended to be used as a callback connected to the
“destroy” signal of a widget. You connect gtk_widget_destroyed()
as a signal handler, and pass the address of your widget variable
as user data. Then when the widget is destroyed, the variable will
be set to %NULL. Useful for example to avoid multiple copies
of the same dialog.
Detaches the menu from the widget to which it had been attached.
This function will call the callback function, detacher, provided
when the gtk_menu_attach_to_widget() function was called.
This function is equivalent to gtk_drag_begin_with_coordinates(), passing -1, -1 as coordinates.
The targets (data formats) in which the source can provide the data
A bitmask of the allowed drag actions for this drag
The button the user clicked to start the drag
The event that triggered the start of the drag, or %NULL if none can be obtained.
Initiates a drag on the source side. The function only needs to be used when the application is starting drags itself, and is not needed when gtk_drag_source_set() is used.
The event is used to retrieve the timestamp that will be used internally to
grab the pointer. If event is %NULL, then %GDK_CURRENT_TIME will be used.
However, you should try to pass a real event in all cases, since that can be
used to get information about the drag.
Generally there are three cases when you want to start a drag by hand by calling this function:
During a #GtkWidget::button-press-event handler, if you want to start a drag
immediately when the user presses the mouse button. Pass the event
that you have in your #GtkWidget::button-press-event handler.
During a #GtkWidget::motion-notify-event handler, if you want to start a drag
when the mouse moves past a certain threshold distance after a button-press.
Pass the event that you have in your #GtkWidget::motion-notify-event handler.
During a timeout handler, if you want to start a drag after the mouse button is held down for some time. Try to save the last event that you got from the mouse, using gdk_event_copy(), and pass it to this function (remember to free the event with gdk_event_free() when you are done). If you really cannot pass a real event, pass %NULL instead.
The targets (data formats) in which the source can provide the data
A bitmask of the allowed drag actions for this drag
The button the user clicked to start the drag
The event that triggered the start of the drag, or %NULL if none can be obtained.
The initial x coordinate to start dragging from, in the coordinate space of widget. If -1 is passed, the coordinates are retrieved from event or the current pointer position
The initial y coordinate to start dragging from, in the coordinate space of widget. If -1 is passed, the coordinates are retrieved from event or the current pointer position
Checks to see if a mouse drag starting at (start_x, start_y) and ending
at (current_x, current_y) has passed the GTK+ drag threshold, and thus
should trigger the beginning of a drag-and-drop operation.

Add the image targets supported by #GtkSelectionData to
the target list of the drag destination. The targets
are added with info = 0. If you need another value,
use gtk_target_list_add_image_targets() and
gtk_drag_dest_set_target_list().
Add the text targets supported by #GtkSelectionData to
the target list of the drag destination. The targets
are added with info = 0. If you need another value,
use gtk_target_list_add_text_targets() and
gtk_drag_dest_set_target_list().
Add the URI targets supported by #GtkSelectionData to
the target list of the drag destination. The targets
are added with info = 0. If you need another value,
use gtk_target_list_add_uri_targets() and
gtk_drag_dest_set_target_list().
Looks for a match between the supported targets of context and the
dest_target_list, returning the first matching target, otherwise
returning %GDK_NONE. dest_target_list should usually be the return
value from gtk_drag_dest_get_target_list(), but some widgets may
have different valid targets for different parts of the widget; in
that case, they will have to implement a drag_motion handler that
passes the correct target list to this function.
drag context
list of droppable targets, or %NULL to use gtk_drag_dest_get_target_list (widget).
Returns the list of targets this widget can accept from drag-and-drop.
Returns whether the widget has been configured to always emit #GtkWidget::drag-motion signals.
Sets a widget as a potential drop destination, and adds default behaviors.
The default behaviors listed in flags have an effect similar
to installing default handlers for the widget’s drag-and-drop signals
(#GtkWidget::drag-motion, #GtkWidget::drag-drop, ...). They all exist
for convenience. When passing #GTK_DEST_DEFAULT_ALL for instance it is
sufficient to connect to the widget’s #GtkWidget::drag-data-received
signal to get primitive, but consistent drag-and-drop support.
Things become more complicated when you try to preview the dragged data,
as described in the documentation for #GtkWidget::drag-motion. The default
behaviors described by flags make some assumptions, that can conflict
with your own signal handlers. For instance #GTK_DEST_DEFAULT_DROP causes
invokations of gdk_drag_status() in the context of #GtkWidget::drag-motion,
and invokations of gtk_drag_finish() in #GtkWidget::drag-data-received.
Especially the later is dramatic, when your own #GtkWidget::drag-motion
handler calls gtk_drag_get_data() to inspect the dragged data.
There’s no way to set a default action here, you can use the #GtkWidget::drag-motion callback for that. Here’s an example which selects the action to use depending on whether the control key is pressed or not:
static void
drag_motion (GtkWidget *widget,
GdkDragContext *context,
gint x,
gint y,
guint time)
{
GdkModifierType mask;
gdk_window_get_pointer (gtk_widget_get_window (widget),
NULL, NULL, &mask);
if (mask & GDK_CONTROL_MASK)
gdk_drag_status (context, GDK_ACTION_COPY, time);
else
gdk_drag_status (context, GDK_ACTION_MOVE, time);
}
which types of default drag behavior to use

If %TRUE, send the same coordinates to the destination, because it is an embedded subwindow.
Sets the target types that this widget can accept from drag-and-drop. The widget must first be made into a drag destination with gtk_drag_dest_set().
list of droppable targets, or %NULL for none
Tells the widget to emit #GtkWidget::drag-motion and #GtkWidget::drag-leave events regardless of the targets and the %GTK_DEST_DEFAULT_MOTION flag.
This may be used when a widget wants to do generic actions regardless of the targets that the source offers.
whether to accept all targets
Clears information about a drop destination set with gtk_drag_dest_set(). The widget will no longer receive notification of drags.
Gets the data associated with a drag. When the data
is received or the retrieval fails, GTK+ will emit a
#GtkWidget::drag-data-received signal. Failure of the retrieval
is indicated by the length field of the selection_data
signal parameter being negative. However, when gtk_drag_get_data()
is called implicitely because the %GTK_DEST_DEFAULT_DROP was set,
then the widget will not receive notification of failed
drops.
the drag context
the target (form of the data) to retrieve
a timestamp for retrieving the data. This will generally be the time received in a #GtkWidget::drag-motion or #GtkWidget::drag-drop signal
Highlights a widget as a currently hovered drop target. To end the highlight, call gtk_drag_unhighlight(). GTK+ calls this automatically if %GTK_DEST_DEFAULT_HIGHLIGHT is set.
Add the writable image targets supported by #GtkSelectionData to
the target list of the drag source. The targets
are added with info = 0. If you need another value,
use gtk_target_list_add_image_targets() and
gtk_drag_source_set_target_list().
Add the text targets supported by #GtkSelectionData to
the target list of the drag source. The targets
are added with info = 0. If you need another value,
use gtk_target_list_add_text_targets() and
gtk_drag_source_set_target_list().
Add the URI targets supported by #GtkSelectionData to

Undoes the effects of gtk_drag_source_set().
Removes a highlight set by gtk_drag_highlight() from a widget.
Draws widget to cr. The top left corner of the widget will be
drawn to the currently set origin point of cr.
You should pass a cairo context as cr argument that is in an
original state. Otherwise the resulting drawing is undefined. For
example changing the operator using cairo_set_operator() or the
line width using cairo_set_line_width() might have unwanted side
effects.
You may however change the context’s transform matrix - like with
cairo_scale(), cairo_translate() or cairo_set_matrix() and clip
region with cairo_clip() prior to calling this function. Also, it
is fine to modify the context with cairo_save() and
cairo_push_group() prior to calling this function.
Note that special-purpose widgets may contain special code for rendering to the screen and might appear differently on screen and when rendered using gtk_widget_draw().
