Dear All:

What would the the easiest way to create a very simple GUI, basically a couple of buttons, each button being associated with a user-defined Python function? In other words, is there any way to use snippets such as PyQt5 hello world example, Python GUI - Python from the Slicer’s Python interpreter?

With the dev version, I’m running into: “Reason: Incompatible library version: QtWidgets.so requires version 5.13.0 or later, but QtWidgets provides version 5.10.0.”

Thank you!
Christine

Hi Christine -

Slicer provides everything you need for this - it comes with python and Qt already installed.

Here’s an example of what you can do at the python prompt in Slicer:

>>> b = qt.QPushButton("click me")
>>> b.connect('clicked()', lambda : print('clicked!'))
True
>>> b.show()

There’s a lot more of course, but here’s the starting point:

Let us know if you don’t find what you need.

There are some more Slicer module development tutorials here that reflect recent developments (e.g., use Qt Designer to create module GUI).

Yes, the Perk lab tutorials are great too - I updated the Start Here wiki page to point there as well.

Dear Steve and Andras:

Thank you so much, these are exactly the pointers I was looking for. To put things into context, I had students over summer working on an image segmentation project (not under my direct supervision, so I am somehow familiar with the project, but not aware of all the technical aspects): https://github.com/EricaMoreira/SlicerSemSeg.

My sense was that a (Slicer-based) very simple GUI could be built to wrap Step 6 --> Step 20 of their project and make the user experience more pleasant. I need some time to go through the resources that you suggested, but my sense is that it shouldn’t take too much effort!

Thanks again for your help!
Christine

Your results look very nice and it should not be hard to package everything nicely in a Slicer extension so that you don’t need any manual installation/configuration. If you need any help with this then feel free to post specific questions as new topics.
