Why is my Qt setgeometry not working?
Adding setGeometry (0, 0, 400, 300); in Widget constructor removes the issue. But the window will not be positioned beautifully at the center of the screen. This warning happens (at least to me) when the size of the widget results to be very small. You should also parent your widget to a QMainWindow, but will still work.
