Class
GtkPopoverMenu
Description [src]
final class Gtk.PopoverMenu : Gtk.Popover
implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget, Gtk.Native, Gtk.ShortcutManager {
/* No available fields */
}
GtkPopoverMenu
is 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 GtkPopoverMenu:flags
controls this appearance.
GtkPopoverMenu
is meant to be used primarily with menu models,
using gtk_popover_menu_new_from_model()
. If you need to put
other widgets such as a GtkSpinButton
or a GtkSwitch
into a popover,
you can use gtk_popover_menu_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
gtk_application_set_menubar()
. - “custom”: a string used to match against the ID of a custom child added with
gtk_popover_menu_add_child()
,gtk_popover_menu_bar_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
GtkTextDirection
to 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
Menu items will also show accelerators, which are usually associated
with actions via gtk_application_set_accels_for_action()
,
gtk_widget_class_add_binding_action()
or
gtk_shortcut_controller_add_shortcut()
.
Shortcuts and Gestures
GtkPopoverMenu
supports the following keyboard shortcuts:
- Space activates 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 button
s. 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 GTK_ACCESSIBLE_ROLE_MENU
role, and its
items use the GTK_ACCESSIBLE_ROLE_MENU_ITEM
,
GTK_ACCESSIBLE_ROLE_MENU_ITEM_CHECKBOX
or
GTK_ACCESSIBLE_ROLE_MENU_ITEM_RADIO
roles, depending on the
action they are connected to.
