Answer 1

Try to use: ajustSize()

Looks To be the problem: Why am I getting QWindowsWindow::setGeometry: Unable to set geometry warning with Qt 5.12.0

A possible solution: Qt Unable to set geometry

Answer 2

This warning happens (at least to me) when the size of the widget results to be very small.

Set a minimum size for your widget (so it will be automatically positioned), like:

 // Widget constructor

 QVBoxLayout* vLayout = new QVBoxLayout();
 setLayout(vLayout);

 setMinimumSize(200,200);

You should also parent your widget to a QMainWindow, but will still work.
