Unfortunately thats not how it looks here.
When I create a control with GTK_SELECTION_MULTIPLE and just click on
the item - it works just like single selection.
In order to select multiple strings I have to press Ctrl key.

Does it work for you?
Maybe some other code here prevents it to work like this?

Thank you.
