Method Details

onTreeListModelCreateModelFunc

ListModel onTreeListModelCreateModelFunc(CallbackHandler __self,
 @Nonnull
 Pointer item,
 @Nullable
 Pointer user_data)

Prototype of the function called to create new child models when
gtk_tree_list_row_set_expanded() is called.

This function can return %NULL to indicate that @item is guaranteed to be
a leaf node and will never have children. If it does not have children but
may get children later, it should return an empty model that is filled once
children arrive.

Parameters:

item - The item that is being expanded

user_data - User data passed when registering the function

Returns:

The model tracking the children of @item or %NULL if @item can never have children
