Description
The provided example produces this warning:
QWindowsWindow::setGeometry: Unable to set geometry 22x22-1300+676 (frame: 38x61-1308+645) on QWidgetWindow/"QDialogClassWindow" on "\\.\DISPLAY3". Resulting geometry: 54x22-1300+676 (frame: 70x61-1308+645) margins: 8, 31, 8, 8 minimum size: 22x22 MINMAXINFO(maxSize=POINT(x=0, y=0), maxpos=POINT(x=0, y=0), maxtrack=POINT(x=0, y=0), mintrack=POINT(x=38, y=61)))
It goes away when setting a minimum size on the dialog for this simple example but for my use case in a more complicated setup it is triggered by having a QLabel with word wrap enabled which I seem to not be able to get away from.
I debugged it a bit and there seems to be a mismatch between the QWindows understanding of the geometry and the platform window.
qwindowsd.dll!QWindowsBaseWindow::setGeometry_sys(const QRect & rect) Line 2125 C++ qwindowsd.dll!QWindowsWindow::setGeometry(const QRect & rectIn) Line 1989 C++ Qt6Guid.dll!QWindow::setGeometry(const QRect & rect) Line 1763 C++ Qt6Guid.dll!QWindow::setPosition(const QPoint & pt) Line 1898 C++ Qt6Guid.dll!QWindow::setPosition(int posx, int posy) Line 1910 C++ Qt6Widgetsd.dll!QWidgetPrivate::setGeometry_sys(int x, int y, int w, int h, bool isMove) Line 7144 C++ Qt6Widgetsd.dll!QWidget::move(const QPoint & p) Line 6989 C++ Qt6Widgetsd.dll!QDialog::adjustPosition(QWidget * w) Line 967 C++ Qt6Widgetsd.dll!QDialog::showEvent(QShowEvent * event) Line 870 C++
In this callstack setGeometry on the widget is called with the correct size, but in the QWindow::setPosition the size returned is wrong, I assume its the size before the layout has been evaluated.
