Generated metadata helpers for MapListModel class surfaces.

Methods

• properties ()

  Returns property metadata for MapListModel.

  • @r A list.

class: MapListModel

[22:7] extends: object

A list model that maps the items in another model to different items. GtkMapListModel uses a [callback@Gtk.MapListModelMapFunc]. Example: Create a list of GtkEventControllers c static gpointer map_to_controllers (gpointer widget, gpointer data) { gpointer result = gtk_widget_observe_controllers (widget); g_object_unref (widget); return result; } widgets = gtk_widget_observe_children (widget); controllers = gtk_map_list_model_new (widgets, map_to_controllers, NULL, NULL); model = gtk_flatten_list_model_new (GTK_TYPE_EVENT_CONTROLLER, controllers); GtkMapListModel will attempt to discard the mapped objects as soon as they are no longer needed and recreate them if necessary. GtkMapListModel passes through sections from the underlying model.

Methods

• MapListModel (Handle = null)

  Creates a new MapListModel by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asObject ()

  Wraps this handle as Object.

  • @r A Object object.

• asListModel ()

  Wraps this handle as ListModel.

  • @r A ListModel object.

• asSectionModel ()

  Wraps this handle as SectionModel.

  • @r A SectionModel object.

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setModel (object Value)

  The model being mapped.

  • @p Value is the new property value.
  • @r None.

• get_model ()

  Gets the model that is currently being mapped or %NULL if none.

• has_map ()

  Checks if a map function is currently set on @self.

• set_model (object model)

  Sets the model to be mapped. GTK makes no effort to ensure that @model conforms to the item type expected by the map function. It assumes that the caller knows what they are doing and have set up an appropriate map function.

  • @p model is The model to be mapped.
  • @r None.

• model ()

  Returns get_model as an Aussom list of wrapper objects. This companion method materializes the full collection up front; use get_model() when lazy or change-notify access is required.

  • @r An Aussom list of elements.
