In a python program we are developing with pyGTK, we need to have a button that launches a new popup window, in which the user can select some elements and then click OK, and these elements should be returned to the mail program window (i.e. the program should receive some references to the selected elements etc.).
What approach should we use?
Is a plug - socket relationship between the windows, the proper way to do it, or are there a more simple solution to just spawn a new window, that is able to return data to the parent window?
