Gtk.Flow_Box.Bind_Model_User_Data

Description

Bind_Model

procedure Bind_Model
   (Self               : not null access Gtk.Flow_Box.Gtk_Flow_Box_Record'Class;
    Model              : Glib.List_Model.Glist_Model;
    Create_Widget_Func : Gtk_Flow_Box_Create_Widget_Func;
    User_Data          : User_Data_Type)

Binds Model to Box. If Box was already bound to a model, that previous binding is destroyed. The contents of Box are cleared and then filled with widgets that represent items from Model. Box is updated whenever Model changes. If Model is null, Box is left empty. It is undefined to add or remove widgets directly (for example, with [methodGtk.FlowBox.insert]) while Box is bound to a model. Note that using a model is incompatible with the filtering and sorting functionality in GtkFlowBox. When using a model, filtering and sorting should be implemented by the model.
