文件： gtkmenubutton.c 项目： ahodesuka/gtk

/**
 * gtk_menu_button_set_menu_model:
 * @menu_button: a #GtkMenuButton
 * @menu_model: (allow-none): a #GMenuModel
 *
 * Sets the #GMenuModel from which the popup will be constructed,
 * or %NULL to disable the button.
 *
 * Depending on the value of #GtkMenuButton:use-popover, either a
 * #GtkMenu will be created with gtk_menu_new_from_model(), or a
 * #GtkPopover with gtk_popover_new_from_model(). In either case,
 * actions will be connected as documented for these functions.
 *
 * If #GtkMenuButton:popup or #GtkMenuButton:popover are already set,
 * their content will be lost and replaced by the newly created popup.
 *
 * Since: 3.6
