* GtkPopoverMenu:
|
|
*
|
|
* `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.
|
|
*
|
|
* `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.
|
|
*
|
|
* ```xml
|
|
* <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
|
|
* - "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 determine
|
|
* if a submenu can be opened
|
|
* - "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 `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 [method@Gtk.Application.set_accels_for_action],
|
|
* [id@gtk_widget_class_add_binding_action] or
|
|
* [method@Gtk.ShortcutController.add_shortcut].
|
|
*
|
|
* # 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 popover's main node.
|
|
*
|
|
* # 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.
