GI.Gtk.Objects.PopoverMenu

GtkPopoverMenu is a subclass of Popover that treats its children like menus and allows switching between them. It is meant to be used primarily together with ModelButton, but any widget can be used, such as SpinButton or Scale. In this respect, GtkPopoverMenu is more flexible than popovers that are created from a MenuModel with popoverNewFromModel.

To add a child as a submenu, set the PopoverMenu:submenu child property to the name of the submenu. To let the user open this submenu, add a ModelButton whose ModelButton:menu-name property is set to the name you've given to the submenu.

By convention, the first child of a submenu should be a ModelButton to switch back to the parent menu. Such a button should use the ModelButton:inverted and ModelButton:centered properties to achieve a title-like appearance and place the submenu indicator at the opposite side. To switch back to the main menu, use "main" as the menu name.

Example

<object class="GtkPopoverMenu">
  <child>
    <object class="GtkBox">
      <property name="visible">True</property>
      <property name="margin">10</property>
      <child>
        <object class="GtkModelButton">
          <property name="visible">True</property>
          <property name="action-name">win.frob</property>
          <property name="text" translatable="yes">Frob</property>
        </object>
      </child>
      <child>
        <object class="GtkModelButton">
          <property name="visible">True</property>
          <property name="menu-name">more</property>
          <property name="text" translatable="yes">More</property>
        </object>
      </child>
    </object>
  </child>
  <child>
    <object class="GtkBox">
      <property name="visible">True</property>
      <property name="margin">10</property>
      <child>
        <object class="GtkModelButton">
          <property name="visible">True</property>
          <property name="action-name">win.foo</property>
          <property name="text" translatable="yes">Foo</property>
        </object>
      </child>
      <child>
        <object class="GtkModelButton">
          <property name="visible">True</property>
          <property name="action-name">win.bar</property>
          <property name="text" translatable="yes">Bar</property>
        </object>
      </child>
    </object>
    <packing>
      <property name="submenu">more</property>
    </packing>
  </child>
</object>

Just like normal popovers created using gtk_popover_new_from_model, PopoverMenu instances have a single css node called "popover" and get the .menu style class.

type ParentTypes PopoverMenu = Popover ': (Bin ': (Container ': (Widget ': (Object ': (ImplementorIface ': (Buildable ': ([] :: [Type])))))))

class (GObject o, IsDescendantOf PopoverMenu o) => IsPopoverMenu o

Type class for types which can be safely cast to PopoverMenu, for instance with toPopoverMenu.

Instances

(GObject o, IsDescendantOf PopoverMenu o) => IsPopoverMenu o

Defined in GI.Gtk.Objects.PopoverMenu

toPopoverMenu :: (MonadIO m, IsPopoverMenu o) => o -> m PopoverMenu

Cast to PopoverMenu, for types for which this is known to be safe. For general casts, use castTo.

noPopoverMenu :: Maybe PopoverMenu

A convenience alias for Nothing :: Maybe PopoverMenu.

Methods

new

popoverMenuNew

Arguments

:: (HasCallStack, MonadIO m)

=> m PopoverMenu

Returns: a new PopoverMenu

Creates a new popover menu.

Since: 3.16

openSubmenu

popoverMenuOpenSubmenu

Arguments

:: (HasCallStack, MonadIO m, IsPopoverMenu a)

=> a

popover: a PopoverMenu

-> Text

name: the name of the menu to switch to

-> m ()

Opens a submenu of the popover. The name must be one of the names given to the submenus of popover with PopoverMenu:submenu, or "main" to switch back to the main menu.

ModelButton will open submenus automatically when the ModelButton:menu-name property is set, so this function is only needed when you are using other kinds of widgets to initiate menu changes.

Since: 3.16

Properties

No description available in the introspection data.

clearPopoverMenuVisibleSubmenu :: (MonadIO m, IsPopoverMenu o) => o -> m ()

Set the value of the “visible-submenu” property to Nothing. When overloading is enabled, this is equivalent to

clear #visibleSubmenu

constructPopoverMenuVisibleSubmenu :: IsPopoverMenu o => Text -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “visible-submenu” property. This is rarely needed directly, but it is used by new.

getPopoverMenuVisibleSubmenu :: (MonadIO m, IsPopoverMenu o) => o -> m (Maybe Text)

Get the value of the “visible-submenu” property. When overloading is enabled, this is equivalent to

get popoverMenu #visibleSubmenu

setPopoverMenuVisibleSubmenu :: (MonadIO m, IsPopoverMenu o) => o -> Text -> m ()

Set the value of the “visible-submenu” property. When overloading is enabled, this is equivalent to

set popoverMenu [ #visibleSubmenu := value ]
