QDesktopWidget Screenshot && Mouse grab

[patrik08]

I discovery a way to build mpg4 video from image.... on linux...
Now my question how i can grab Mouse to. ++

To build a video screen presentation from a programm... on action...

QDesktopWidget *desk = qApp->desktop();
QPixmap desktopscreen = QPixmap::grabWindow(desk->screen()->winId());

QDesktopWidget *desk = qApp->desktop();
QPixmap desktopscreen = QPixmap::grabWindow(desk->screen()->winId());

To copy to clipboard, switch view to plain text mode

In general you can't. When I implemented my videograbber I just painter the cursor on the frame myself

I don't understand what you mean, but if you want to receive mouse move events even if the button is not pressed, you need to enable mouse tracking on the widget you wish to track.

In my grabber I just used QCursor::pos.
