A gtk.MenuShell is a container of gtk.MenuItem objects arranged in a list which can be navigated, selected, and activated by the user to perform application functions. A gtk.MenuItem can have a submenu associated with it, allowing for nested hierarchical menus.
A menu item can be “selected”, this means that it is displayed in the prelight state, and if it has a submenu, that submenu will be popped up.
A menu is “active” when it is visible onscreen and the user is selecting from it. A menubar is not active until the user clicks on one of its menuitems. When a menu is active, passing the mouse over a submenu will pop it up.
There is also is a concept of the current menu and a current menu item. The current menu item is the selected menu item that is furthest down in the hierarchy. (Every active menu shell does not necessarily contain a selected menu item, but if it does, then the parent menu shell must also contain a selected menu item.) The current menu is the menu that contains the current menu item. It will always have a GTK grab and receive all key presses.
Sets our main struct and passes it to the parent class.
Activates the menu item within the menu shell.
An action signal that activates the current menu item within the menu shell.
An action signal which cancels the selection within the menu shell. Causes the selection-done signal to be emitted.
A keybinding signal which moves the focus in the given direction.
This signal is emitted when a menu shell is deactivated.
An keybinding signal which moves the current menu item in the direction specified by direction.
The ::move-selected signal is emitted to move the selection to another item.
This signal is emitted when a selection has been completed within a menu shell.
Adds a new gtk.MenuItem to the end of the menu shell's item list.
Cancels the selection within the menu shell.
Deactivates the menu shell.
Deselects the currently selected item from the menu shell, if any.
Get the main Gtk struct
Gets the parent menu shell.
Gets the currently selected item.
the main Gtk struct as a void*
Returns TRUE if the menu shell will take the keyboard focus on popup.
Adds a new gtk.MenuItem to the menu shell’s item list at the position indicated by position.
Adds a new gtk.MenuItem to the beginning of the menu shell's item list.
Select the first visible or selectable child of the menu shell; don’t select tearoff items unless the only item is a tearoff item.
Selects the menu item from the menu shell.
If take_focus is TRUE (the default) the menu shell will take the keyboard focus so that it will receive all keyboard events which is needed to enable keyboard navigation in menus.

Removes all widgets from the container
Adds widget to container. Typically used for simple containers such as gtk.Window, gtk.Frame, or gtk.Button; for more complicated layout containers such as gtk.Box or gtk.Grid, this function will pick default packing parameters that may not be correct. So consider functions such as Box.packStart and Grid.attach as an alternative to 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.
Gets the value of a child property for child and container.
Gets the values of one or more child properties for child and container.
Emits a child-notify signal for the [child property][child-properties] child_property on the child.
Emits a child-notify signal for the [child property][child-properties] specified by pspec on the child.
Sets a child property for child and container.
Sets one or more child properties for child and container.
Returns the type of the children supported by the container.
Invokes callback on each direct child of container, including children that are considered “internal” (implementation details of the container). “Internal” children generally weren’t added by the user of the container, but were added by the container implementation itself.
Invokes callback on each non-internal child of container. See Container.forall for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls.
Retrieves the border width of the container. See Container.setBorderWidth.
Returns the container’s non-internal children. See Container.forall for details on what constitutes an "internal" child.
Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores NULL in focusable_widgets and returns FALSE.
Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling Window.getFocus.
Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().
Retrieves the vertical focus adjustment for the container. See Container.setFocusVadjustment.
Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including child.
Returns the resize mode for the container. See gtk_container_set_resize_mode ().
When a container receives a call to the draw function, it must send synthetic draw calls to all children that don’t have their own gdk.Windows This function provides a convenient way of doing this. A container, when it receives a call to its draw function, calls Container.propagateDraw once for each child, passing in the cr the container received.
Removes widget from container. widget must be inside container. Note that container will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it before removing it from a container, using g_object_ref(). If you don’t want to use widget again it’s usually more efficient to simply destroy it directly using Widget.destroy since this will remove it from the container and help break any circular reference count cycles.
Sets the border width of the container.
Sets a focus chain, overriding the one computed automatically by GTK+.
Sets, or unsets if child is NULL, the focused child of container.
Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See ScrolledWindow.getHadjustment for a typical way of obtaining the adjustment and Container.setFocusVadjustment for setting the vertical adjustment.
Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the vertical alignment. See ScrolledWindow.getVadjustment for a typical way of obtaining the adjustment and Container.setFocusHadjustment for setting the horizontal adjustment.
Sets the reallocate_redraws flag of the container to the given value.
Sets the resize mode for the container.
Removes a focus chain explicitly set with Container.setFocusChain.
