Windows: Only initial QScreen values are available if screen geometry changes between QApplication and before first window is open

XMLWordPrintable

    • Windows
    • fa0b2ef81c (qt/qtbase/dev) fa0b2ef81c (qt/tqtc-qtbase/dev) 7a3aa146a5 (qt/qtbase/6.4) 07ee9f9774 (qt/qtbase/6.3) 07ee9f9774 (qt/tqtc-qtbase/6.3)

      To reproduce:

      • modify attached example with valid resolutions for your display (2 functions)
      • run the example

      Ideally it should show valid resolution when in "low" resolution step, but instead it shows the initial resolution.

      Seems like screen changes come through window events and since there is no window yet, Qt does not get one either. Perhaps this could be fixed by querying screen properties again when first window is shown.
