[Qt-interest] qwidget grabmouse weird behaviour

[Giancarlo Amati]

mmmm sounds good to me, but mapTo or any others map...refferted to the widget or to the main window where my widget is the central one....sorry I'm very new to QT.

Kind Regards.

Can't the point obtained here be mapped to the widgetby using mapTo(QWidget *, const QPoint &)

Hello everybody,

QVTKWidget is a class derived from QWidget...and I'm using the fuction grabMouse to detect the position of the mouse.
Now, I would love the position of the cursor respect the position and the dimension of the widget and not respect my screen resolution, infact:


_ui->qvtkWidget->grabMouse(mc);
 QPoint p = mc.pos();
 printf("Point: %d %d", p.x(), p.y());
 _ui->qvtkWidget->releaseMouse();

where qvtkWidget is the widget. Now mc is filled up with my the position of the mouse respect to the dimensions and resolution of the screen and not respect to the widget itself.

WHY?

Kind Regards.
Giancarlo
