MenuButton.setMenuModel
void setMenuModel(gio.menu_model.MenuModel menuModel = null)Sets the #GMenuModel from which the popup will be constructed, or null to dissociate any existing menu model and disable the button.
Depending on the value of #GtkMenuButton:use-popover, either a #GtkMenu will be created with [gtk.menu.Menu.newFromModel], or a #GtkPopover with [gtk.popover.Popover.newFromModel]. In either case, actions will be connected as documented for these functions.
If #GtkMenuButton:popup or #GtkMenuButton:popover are already set, those widgets are dissociated from the menu_button, and those properties are set to null.
Parameters
menuModel | a #GMenuModel, or null to unset and disable the button |
