The gtkmm tutorial Treeview sections gives an example of getting
multiple selections using the selected_foreach_iter() slot, but I want
to try get_selected_rows(). I don't know how to use the return value
though, ListHandle_Path. Could someone explain or show me a simple
example?
Thanks

Gtk::TreeSelection::get_selected_rows() returns a ListHandle_Path which
has an operator that lets you convert it to a
std::vector<Gtk::TreeModel::Path>.
Ok... here's what you should do:
// code snippet starts
// all this presupposes you've set up your tree view, a list or tree
store, and a tree view selection somewhere previously
std::vector<Gtk::TreeModel::Path> pathlist;
pathlist = myTreeViewSelection->get_selected_rows();
// Now, you have a list of paths to the selected rows. For each entry
in the list, you can get an iterator which can be deferenced to a
Gtk::TreeView::Row.
for(gint i = 0; i < pathlist.size(); i++)
{
Gtk::TreeModel::iterator iter =
myTreeView->get_model().get_iter(pathlist[i]);
Gtk::TreeModel::Row row = *iter;
// now do what you need to do with the data in your TreeModel
}
//code snippet ends
As always, if I'm all wet, you guys correct me.
Hope this helps.
Bob
