If the application uses *.glade or *.ui files you can - depending on how well it is designed re-arrange certain elements and swap out container types.
If there are no such files, you are out of luck. Then the ui is "hard"-coded (as hard as python code can get..) and you have to mod... | 0 | 285 | 0 | 0 | 2014-11-25T12:58:00.000 | python,gtk | load an already written GTK python codes into a GUI designer | 0 | 2 | 2 | 27,137,234 | 1 |
