Widget geometry issue

Cobra91151

Hi! I want to save window geometry to the registry. It all works fine but sometimes I get QWindowsWindow::setGeometry: Unable to set geometry error.

And registry data is @Rect(32775 32798 1334 600)
x - 32775
y - 32798

I think it's out of bounds of my screen. How to get max X and Y of the screen to check values before setting the geometry. Thanks.

Usually this is caused by having the app on a secondary screen. I usually check desktops and make sure if I'm on a system that doesn't have multiple screens I restore my geometry to the main window.

Something like:

    auto desktop = QApplication::desktop();
    auto screenLocation = desktop->screenNumber(this);
    if (screenLocation == -1)
    {
        qWarning() << "Main window is not on a valid screen, moving to main screen";
        move(20, 20);
    }

If that isn't what the issue is, then to answer your question you can get the screen geometry with:

const QRect QDesktopWidget::screenGeometry(int screen = -1) const

And you can get the desktop widget via application like I did above.

I would figure out why you are having bad data saved for the geometry though.

I have fixed it by setting nativeEvent and checking for message - SIZE_MAXIMIZED. When window is maximized the values are not saved. Thanks.
