Interface

Gtk-4.0 ▶ Gtk ▶ SectionModel ▶ Interface

Interface for implementing SectionModel. Contains only the virtual methods that need to be implemented.

interface Interface<A extends GObject.Object = GObject.Object> {
    vfunc_get_item(position: number): GObject.Object;
    vfunc_get_item_type(): GType;
    vfunc_get_n_items(): number;
    vfunc_get_section(position: number): [number, number];
}

Methods

vfunc_get_section

Methods - Inherited from Gio

vfunc_get_item vfunc_get_item_type vfunc_get_n_items

Methods

  • Query the section that covers the given position. The number of items in the section can be computed by out_end - out_start.

    If the position is larger than the number of items, a single range from n_items to G_MAXUINT will be returned.

    Parameters

    • position: number

      the position of the item to query

    Returns [number, number]

Methods - Inherited from Gio

  • Gets the type of the items in list.

    All items returned from g_list_model_get_item() are of the type returned by this function, or a subtype, or if the type is an interface, they are an implementation of that interface.

    The item type of a Gio.ListModel can not change during the life of the model.

    Returns GType

  • Gets the number of items in list.

    Depending on the model implementation, calling this function may be less efficient than iterating the list with increasing values for position until g_list_model_get_item() returns null.

    Returns number
