[gtkmm] How to clear a tree view?

["Andreas B. Thun" <abt gmx de>]

Hi!

I´ve added some rows with data to a list store tree view
using m_list_store_ref->append().

Later in my application I want to clear the
rows to display completely new values. How can I clear
all rows from the displayed treeView?



TIA,
Andi
