## Description

GtkModelButton is a button class that can use a GAction as its model. In contrast to GtkToggleButton or GtkRadioButton, which can also be backed by a GAction via the “action-name” property, GtkModelButton will adapt its appearance according to the kind of action it is backed by, and appear either as a plain, check or radio button.

Model buttons are used when popovers from a menu model with `gtk_popover_new_from_model()`; they can also be used manually in a GtkPopoverMenu.

When the action is specified via the “action-name” and “action-target” properties, the role of the button (i.e. whether it is a plain, check or radio button) is determined by the type of the action and doesn't have to be explicitly specified with the “role” property.

The content of the button is specified by the “text” and “icon” properties.

The appearance of model buttons can be influenced with the “centered” and “iconic” properties.

Model buttons have built-in support for submenus in GtkPopoverMenu. To make a GtkModelButton that opens a submenu when activated, set the “menu-name” property. To make a button that goes back to the parent menu, you should set the “inverted” property to place the submenu indicator at the opposite side.
