Calling Python Code

Hi All
I'm a total beginner with QtPyVCP and python so please be gentle. I've set out to create my own screenset complete with some conversational gcode generation wizards. I've written some code in Python which generates a txt file with my gcode in it. I've then moved the code over into mainwindow.py and got that working with the screen controls.

As I will have a few conversational tabs, it would seem sensible to have a python file for each routine and call them as required.

I've got the call to the python file working, and when I first click the actionbutton that calls pressme, I get the gcode created. But if i change the value in the doublespin boxes (dsb) and click the action button, the values don't change. By changing the SDia and FDia to fixed values I've proved the value are being passed on the first press of the button, but not subsequent presses.

Any help would be much appreciated so the Gcode is created with the last values entered into the doublespin boxes.
Thanks

Replied by davidimurray on topic Calling Python Code
Fixed the issue by calling the doublespinboxes directly in the function call
self.actionbutton.clicked.connect(lambda: pressme(self.dsb.value(),self.dsb2.value()))
