[Gtk-sharp-list] Query all values from TreeView

[David S]

There is an actual "Foreach" method that you give a TreeModelForeachFunc(
TreeModel, TreePath, TreeIter ) for the TreeModels.

so you could do something like this

mymodel.Foreach( (model, path, iter) => {
   string data = model.GetValue( iter, 0 );
   // manipulate data
   return false; // a return value of true stops the foreach
} );
