I’ve tried to update the current scripted module template to use a .ui file to generate GUI and it worked really well. It reduced and simplified the code a lot.
Reload works nicely: to update the GUI, it is enough to save the .ui file in Qt Designer and click Reload in Slicer.
Widget variables can be automatically exposed as self.ui.myWidget (similarly how variables are accessible in C++ by generating a skeleton file).
I’ve submitted a pull request so that you can have a look: https://github.com/Slicer/Slicer/pull/1072/files#diff-c12bcbe4f4bab89847136fc032496bd4R36
@jcfr It works so nicely that I think it would worth the time adding designer to the package. Could you have a look? If it’s very easy then it might make sense to include it in 4.10.1.
