Struct gtk::PopoverMenu [−][src]
pub struct PopoverMenu(_);
Expand description
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 gio::MenuModel with Popover::from_model().
To add a child as a submenu, set the property::PopoverMenu::submenu
child property to the name of the submenu. To let the user open
this submenu, add a ModelButton whose property::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
property::ModelButton::inverted and property::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.

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.

Implementations
Creates a new builder-pattern struct instance to construct PopoverMenu objects.
This method returns an instance of PopoverMenuBuilder which can be used to create PopoverMenu objects.
Opens a submenu of the self. The name
must be one of the names given to the submenus
of self with property::PopoverMenu::submenu, or
“main” to switch back to the main menu.
ModelButton will open submenus automatically
when the property::ModelButton::menu-name property is set,
so this function is only needed when you are using
other kinds of widgets to initiate menu changes.
name
the name of the menu to switch to
