Design crushing to corner and failing to layout PyQT5

crabcrabcam

I'm kinda new to this so I'm basically just copy pasting the stuff from tutorials I've done to make it work.

I've made a designer.ui file with QtDesigner and now I've exported it to Python code. If I use the -x command then run the design Python it works fine, but if I import it to another file (so I can make connections) then it all crushes down to 1 place rather than sticking to the grid layout base.

If I launch my Main.py file (not designer code) then I get the error QLayout: Attempting to add QLayout "" to MainWindow "MainWindow", which already has a layout but I don't see where I'm adding a layout within my Main code...

My code is: https://gist.github.com/crabcrabcam/3a6a9e847791117616d18ada0895f868

Thanks for any help :) If you need some more stuff just ask.

Hi and welcome to devnet,

self.gridLayout = QtWidgets.QGridLayout(MainWindow) in your MainDes.py triggers the message. Passing a widget as parent of the layout will make the layout applied to that widget. QMainWindow already has the layout that implements all the features like dock handling etc.

On a side note, why QtWidgets.QWidget.__init__(self, parent) and not QtWidgets.QMainWindow.__init__(self, parent) in Main.py ?
