PopoverMenuRef

public struct PopoverMenuRef : PopoverMenuProtocol, GWeakCapturing

GtkPopoverMenu is a subclass of GtkPopover that implements menu behavior.

An example GtkPopoverMenu

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 [ctorGtk.PopoverMenu.new_from_model]. If you need to put other widgets such as a GtkSpinButton or a GtkSwitch into a popover, you can use [methodGtk.PopoverMenu.add_child].

For more dialog-like behavior, use a plain GtkPopover.

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
  • “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 [methodGtk.Application.set_menubar].
  • “custom”: a string used to match against the ID of a custom child added with [methodGtk.PopoverMenu.add_child], [methodGtk.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 [methodGtk.Application.set_accels_for_action], [idgtk_widget_class_add_binding_action] or [methodGtk.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.

The PopoverMenuRef type acts as a lightweight Swift reference to an underlying GtkPopoverMenu instance. It exposes methods that can operate on this data type through PopoverMenuProtocol conformance. Use PopoverMenuRef only as an unowned reference to an existing GtkPopoverMenu instance.

  • ptr
    Untyped pointer to the underlying `GtkPopoverMenu` instance.
    

    For type-safe access, use the generated, typed pointer popover_menu_ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!

    Declaration

    Swift

    @inlinable
    init!(_ maybePointer: UnsafeMutablePointer<GtkPopoverMenu>?)
  • Conditional initialiser from an optional, non-mutable pointer to the underlying C data type

    Declaration

    Swift

  • This factory is syntactic sugar for setting weak pointers wrapped in GWeak<T>

    Declaration

    Swift

    @inlinable
    static func unowned<T>(_ other: T) -> PopoverMenuRef where T : PopoverMenuProtocol
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to PopoverMenuProtocol.

    Declaration

    Swift

    @inlinable
    init<T>(cPointer: UnsafeMutablePointer<T>)
  • Unsafe typed initialiser. Do not use unless you know the underlying data type the pointer points to conforms to PopoverMenuProtocol.

    Declaration

    Declaration

    Swift

    @inlinable
    init(mutating raw: UnsafeRawPointer)

    Declaration

    Swift

    @inlinable
    init(raw: UnsafeMutableRawPointer)

    Declaration

    Swift

    @inlinable
    init(opaquePointer: OpaquePointer)
  • Creates a `GtkPopoverMenu` and populates it according to `model`.
    

    The created buttons are connected to actions found in the GtkApplicationWindow to which the popover belongs - typically by means of being attached to a widget that is contained within the GtkApplicationWindows widget hierarchy.

    Actions can also be added using [methodGtk.Widget.insert_action_group] on the menus attach widget or on any of its parent widgets.

    This function creates menus with sliding submenus. See [ctorGtk.PopoverMenu.new_from_model_full] for a way to control this.

    Declaration

    Swift

    @inlinable
    init<MenuModelT>(model: MenuModelT?) where MenuModelT : MenuModelProtocol
  • Creates a GtkPopoverMenu and populates it according to model.

    The created buttons are connected to actions found in the action groups that are accessible from the parent widget. This includes the GtkApplicationWindow to which the popover belongs. Actions can also be added using [methodGtk.Widget.insert_action_group] on the parent widget or on any of its parent widgets.

    The only flag that is supported currently is GTK_POPOVER_MENU_NESTED, which makes GTK create traditional, nested submenus instead of the default sliding submenus.

    Declaration

    Swift
