Description
For a multi screen setup (seperate X screens, not Xinerama or RandR) Qt 5 does not return the correct screen number for the scond screen when calling QApplication::desktop()->screenNumber().
int screenCount = QApplication::desktop()->screenCount(); qDebug() << "screen count" << screenCount; for (int i = 0; i < screenCount; ++i) { QWidget *widget = QApplication::desktop()->screen(i); int reverseScreenNr = QApplication::desktop()->screenNumber(widget); qDebug() << "root widget for screen" << i << widget << "reverse nr:" << reverseScreenNr; }
While Qt 4 prints
screen count 2 root widget for screen 0 QDesktopWidget(0x9b46148) reverse nr: 0 root widget for screen 1 QWidget(0x9b4e250) reverse nr: 1
as expected Qt 5 returns a reverse screen number of 0 instead of 1
screen count 2 root widget for screen 0 QDesktopScreenWidget(0x8f02798) reverse nr: 0 root widget for screen 1 QDesktopScreenWidget(0x8f01278) reverse nr: 0
