  • Constructor Details

    • Builder

      protected Builder()
      Default constructor for a Builder object.

  • Method Details

    • build

      public MenuModel build()
      Finish building the MenuModel object. This will call GObject.withProperties(Type, String[], Value[]) to create a new GObject instance, which is then cast to MenuModel.
      Overrides:
      build in class GObject.Builder<B extends MenuModel.Builder<B>>
      Returns:
      a new instance of MenuModel with the properties that were set in the Builder object.

    • onItemsChanged

      public B onItemsChanged(MenuModel.ItemsChangedCallback handler)

      Emitted when a change has occurred to the menu.

      The only changes that can occur to a menu is that items are removed or added. Items may not change (except by being removed and added back in the same location). This signal is capable of describing both of those changes (at the same time).

      The signal means that starting at the index position, removed items were removed and added items were added in their place. If removed is zero then only items were added. If added is zero then only items were removed.

      As an example, if the menu contains items a, b, c, d (in that order) and the signal (2, 1, 3) occurs then the new composition of the menu will be a, b, \, \, \_, d (with each _ representing some new item).

      Signal handlers may query the model (particularly the added items) and expect to see the results of the modification that is being reported. The signal is emitted after the modification.

      Parameters:
      handler - the signal handler
      Returns:
      the Builder instance is returned, to allow method chaining
