38  * `GtkPopoverMenu` is a subclass of `GtkPopover` that implements menu
39  * behavior.
40  * 
41  * ![An example GtkPopoverMenu](menu.png)
42  * 
43  * `GtkPopoverMenu` treats its children like menus and allows switching
44  * between them. It can open submenus as traditional, nested submenus,
45  * or in a more touch-friendly sliding fashion.
46  * 
47  * `GtkPopoverMenu` is meant to be used primarily with menu models,
48  * using [ctor@Gtk.PopoverMenu.new_from_model]. If you need to put
49  * other widgets such as a `GtkSpinButton` or a `GtkSwitch` into a popover,
50  * you can use [method@Gtk.PopoverMenu.add_child].
51  * 
52  * For more dialog-like behavior, use a plain `GtkPopover`.
53  * 
54  * ## Menu models
55  * 
56  * The XML format understood by `GtkBuilder` for `GMenuModel` consists
57  * of a toplevel `<menu>` element, which contains one or more `<item>`
58  * elements. Each `<item>` element contains `<attribute>` and `<link>`
59  * elements with a mandatory name attribute. `<link>` elements have the
60  * same content model as `<menu>`. Instead of `<link name="submenu">`
61  * or `<link name="section">`, you can use `<submenu>` or `<section>`
62  * elements.
63  * 
64  * ```xml
65  * <menu id='app-menu'>
66  * <section>
67  * <item>
68  * <attribute name='label' translatable='yes'>_New Window</attribute>
69  * <attribute name='action'>app.new</attribute>
70  * </item>
71  * <item>
72  * <attribute name='label' translatable='yes'>_About Sunny</attribute>
73  * <attribute name='action'>app.about</attribute>
74  * </item>
75  * <item>
76  * <attribute name='label' translatable='yes'>_Quit</attribute>
77  * <attribute name='action'>app.quit</attribute>
78  * </item>
79  * </section>
80  * </menu>
81  * ```
82  * 
83  * Attribute values can be translated using gettext, like other `GtkBuilder`
84  * content. `<attribute>` elements can be marked for translation with a
85  * `translatable="yes"` attribute. It is also possible to specify message
86  * context and translator comments, using the context and comments attributes.
87  * To make use of this, the `GtkBuilder` must have been given the gettext
88  * domain to use.
89  * 
90  * The following attributes are used when constructing menu items:
91  * 
92  * - "label": a user-visible string to display
93  * - "use-markup": whether the text in the menu item includes [Pango markup](https://docs.gtk.org/Pango/pango_markup.html)
94  * - "action": the prefixed name of the action to trigger
95  * - "target": the parameter to use when activating the action
96  * - "icon" and "verb-icon": names of icons that may be displayed
97  * - "submenu-action": name of an action that may be used to track
98  * whether a submenu is open
99  * - "hidden-when": a string used to determine when the item will be hidden.
100  * Possible values include "action-disabled", "action-missing", "macos-menubar".
101  * This is mainly useful for exported menus, see [method@Gtk.Application.set_menubar].
102  * - "custom": a string used to match against the ID of a custom child added with
103  * [method@Gtk.PopoverMenu.add_child], [method@Gtk.PopoverMenuBar.add_child],
104  * or in the ui file with `<child type="ID">`.
105  * 
106  * The following attributes are used when constructing sections:
107  * 
108  * - "label": a user-visible string to use as section heading
109  * - "display-hint": a string used to determine special formatting for the section.
110  * Possible values include "horizontal-buttons", "circular-buttons" and
111  * "inline-buttons". They all indicate that section should be
112  * displayed as a horizontal row of buttons.
113  * - "text-direction": a string used to determine the `GtkTextDirection` to use
114  * when "display-hint" is set to "horizontal-buttons". Possible values
115  * include "rtl", "ltr", and "none".
116  * 
117  * The following attributes are used when constructing submenus:
118  * 
119  * - "label": a user-visible string to display
120  * - "icon": icon name to display
121  * 
122  * Menu items will also show accelerators, which are usually associated
123  * with actions via [method@Gtk.Application.set_accels_for_action],
124  * [id@gtk_widget_class_add_binding_action] or
125  * [method@Gtk.ShortcutController.add_shortcut].
126  * 
127  * # CSS Nodes
128  * 
129  * `GtkPopoverMenu` is just a subclass of `GtkPopover` that adds custom content
130  * to it, therefore it has the same CSS nodes. It is one of the cases that add
131  * a .menu style class to the popover's main node.
132  * 
133  * # Accessibility
134  * 
135  * `GtkPopoverMenu` uses the %GTK_ACCESSIBLE_ROLE_MENU role, and its
136  * items use the %GTK_ACCESSIBLE_ROLE_MENU_ITEM,
137  * %GTK_ACCESSIBLE_ROLE_MENU_ITEM_CHECKBOX or
138  * %GTK_ACCESSIBLE_ROLE_MENU_ITEM_RADIO roles, depending on the
139  * action they are connected to.
