QWidget modification at runtime

SamuraiDestroy

I am trying to make the ui elements of my window resize according to the window size but all the QWidgets stay the same size.
I have them all in a Horizontal Layout with their sizePolicies set appropriately. Here is my code for resizing the window and widgets:

monitor = screeninfo.get_monitors()[0]
x = monitor.width
y = monitor.height

class mainWindow(QtWidgets.QMainWindow):
    def __init__(self):
        super(mainWindow, self).__init__()
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

def refreshWindow():
    # pass
    xn = window.width()
    yn = window.height() # TODO
    window.ui.toolList.resize(toolsScale * xn, toolsScale * yn)
    window.ui.imageViewer.resize(mainScale * xn, mainScale * yn)
    window.ui.layerList.resize(layersScale * xn, layersScale * yn)
    # listX = (toolsScale + mainScale) * xn
    # window.ui.layerList.move(listX, 0)
    print(window.ui.layerList.pos())
    window.ui.layerList.show()
    # Resize window and its elements to fit the screen
    window.show()
# Function to refresh window elements

global window
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    global window
    window = mainWindow()
    window.resize(x, y)
    refreshWindow()
    window.show()
    # Load main window

    sys.exit(app.exec())

Hi,

Since you have a QMainWindow, is your layout applied to the central widget of your QMainWindow ? Or did you try to change the QMainWindow's own layout which is not possible.

@SGaist The layout is applied to the central widget and then all the ui is contained within the layout like this

@SamuraiDestroy
The "red no entry signs" (you must ignore the one on centralWidget I think) indicate you have sub-widgets which do not themselves have any layout, and that may be the cause. You need to eliminate any red no entry signs you see in Designer, except I think on centralWidget which it handles weirdly. If those widgets have child widgets you can click on the parent widget and set layout from there.
