Expand description

Trait containing manually implemented methods of TreeModel.

Required methods

fn get_value(&self, iter: &TreeIter, column: i32) -> Value

fn get<V: for<'b> FromValue<'b> + 'static>(
    &self,
    iter: &TreeIter,
    column: i32
) -> V

Similar to Self::get_value but panics if the value is of a different type.
