[gtkmm] how to find out whether any treeview row is selected

[triendl klaus <triendl kj aon at>]

hi all,

i connected to the TreeSelection::signal_changed signal just to find out whether any number of rows or no row is currently selected to set a button sensitive or not. but i didn't find any method to use.

it's a multiple select treeview and i guess in this case the select_foreach callback is not called back if no row is selected.
