Scripted Extension inheretance

Development
1

Hi everyone!

I was wondering if it was possible to set up an extension that defines a base module type that other modules can then inherit.

Basically what I would like is to have a set of classes that extend the SlicerLoadableModule, then another set extending those classes, e.g.:

foo.py

class foo(ScriptedLoadableModule):
...

class fooWidget(ScriptedLoadableModuleWidget):
...

class fooLogic(ScriptedLoadableModuleLogic):
...

bar.py

class bar(foo):
...

class barWidget(fooWidget):
...

class barLogic(fooLogic):
...

Is it possible to have a set up like this in slicer? Right now I can’t seem to get slicer to detect and load the module when I have it scan the extension directory.

Thanks!

Yes, that should work in theory. You’ll need to be careful about the directories because the module discover process expects to have a working set of module classes that match the filename of the .py file, so you may need to put the abstract classes into a lib folder.
