Variable: PopoverMenu
constPopoverMenu:"PopoverMenu"
Defined in: react/src/generated/jsx.ts:14487
A subclass of GtkPopover that implements menu behavior.
GtkPopoverMenu treats its children like menus and allows switching
between them. It can open submenus as traditional, nested submenus,
or in a more touch-friendly sliding fashion.
The property [property@Gtk.PopoverMenu:flags] controls this appearance.
GtkPopoverMenu is meant to be used primarily with menu models,
using [ctor@Gtk.PopoverMenu.new_from_model]. If you need to put
other widgets such as a GtkSpinButton or a GtkSwitch into a popover,
you can use [method@Gtk.PopoverMenu.add_child].
For more dialog-like behavior, use a plain GtkPopover.
Menu models
The XML format understood by GtkBuilder for GMenuModel consists
of a toplevel <menu> element, which contains one or more <item>
elements. Each <item> element contains <attribute> and <link>
elements with a mandatory name attribute. <link> elements have the
same content model as <menu>. Instead of <link name="submenu">
or <link name="section">, you can use <submenu> or <section>
elements.
<menu id='app-menu'>
<section>
<item>
<attribute name='label' translatable='yes'>_New Window</attribute>
<attribute name='action'>app.new</attribute>
</item>
<item>
<attribute name='label' translatable='yes'>_About Sunny</attribute>
<attribute name='action'>app.about</attribute>
</item>
<item>
<attribute name='label' translatable='yes'>_Quit</attribute>
<attribute name='action'>app.quit</attribute>
</item>
</section>
</menu>
Attribute values can be translated using gettext, like other GtkBuilder
content. <attribute> elements can be marked for translation with a
translatable="yes" attribute. It is also possible to specify message
context and translator comments, using the context and comments attributes.
To make use of this, the GtkBuilder must have been given the gettext
domain to use.
The following attributes are used when constructing menu items:
- "label": a user-visible string to display
- "use-markup": whether the text in the menu item includes Pango markup
- "action": the prefixed name of the action to trigger
- "target": the parameter to use when activating the action
- "icon" and "verb-icon": names of icons that may be displayed
- "submenu-action": name of an action that may be used to track whether a submenu is open
- "hidden-when": a string used to determine when the item will be hidden. Possible values include "action-disabled", "action-missing", "macos-menubar". This is mainly useful for exported menus, see [method@Gtk.Application.set_menubar].
- "custom": a string used to match against the ID of a custom child added with
[method@Gtk.PopoverMenu.add_child], [method@Gtk.PopoverMenuBar.add_child],
or in the ui file with
<child type="ID">.
The following attributes are used when constructing sections:
- "label": a user-visible string to use as section heading
- "display-hint": a string used to determine special formatting for the section. Possible values include "horizontal-buttons", "circular-buttons" and "inline-buttons". They all indicate that section should be displayed as a horizontal row of buttons.
- "text-direction": a string used to determine the
GtkTextDirectionto use when "display-hint" is set to "horizontal-buttons". Possible values include "rtl", "ltr", and "none".
The following attributes are used when constructing submenus:
- "label": a user-visible string to display
- "icon": icon name to display
- "gtk-macos-special": (macOS only, ignored by others) Add special meaning to a menu in the macOS menu bar. See Using GTK on Apple macOS.
Menu items will also show accelerators, which are usually associated with actions via [method@Gtk.Application.set_accels_for_action], [method@WidgetClass.add_binding_action] or [method@Gtk.ShortcutController.add_shortcut].
Shortcuts and Gestures
GtkPopoverMenu supports the following keyboard shortcuts:
Spaceactivates the default widget.
CSS Nodes
GtkPopoverMenu is just a subclass of GtkPopover that adds custom content
to it, therefore it has the same CSS nodes. It is one of the cases that add
a .menu style class to the main popover node.
Menu items have nodes with name button and class .model. If a section
display-hint is set, the section gets a node box with class horizontal
plus a class with the same text as the display hint. Note that said box may
not be the direct ancestor of the item buttons. Thus, for example, to style
items in an inline-buttons section, select .inline-buttons button.model.
Other things that may be of interest to style in menus include label nodes.
Accessibility
GtkPopoverMenu uses the [enum@Gtk.AccessibleRole.menu] role, and its
items use the [enum@Gtk.AccessibleRole.menu_item],
[enum@Gtk.AccessibleRole.checkbox] or [enum@Gtk.AccessibleRole.menu_item_radio]
roles, depending on the action they are connected to.
