[Qt-interest] Re : Re : Rendering widget on Multiple screens

[Martin Guillon]

Here you go. It s an example where I move to the screen the mouse is on:

static int findScreenHoldingMouse()
{
            return QApplication::desktop()->screenNumber(QCursor::pos());
}
;

Then in your code:

int screen = findScreenHoldingMouse();
move(QApplication::desktop()->screenGeometry(screen).x(),
            QApplication::desktop()->screenGeometry(screen).y());

This will move the widget to the 0,0 of the screen where the mouse is. You can replace screen with QApplication::desktop()->primaryScreen() if you want the master screen.

Do you have some sample code related to this? I have posted the results of my experiment in a earlier mail. Could you please point out what might have gone wrong.
