Hello all,
I'm running into a problem where the mouse (and touchscreen) poll rate is
too slow for my application. At first I thought it was the device (mouse
and/or touchscreen), but after trying in different apps, I discovered it
is Qt. I am simply subclassing a QLabel and adding points to a
QPainterPath in mouseMoveEvent like this:
MyLabel::mouseMoveEvent(QMouseEvent *e)
{
if(mouseState==1)
{
addPoint(e->pos());
update();
}
}
The QPainterPath looks fine when you move the mouse/touchscreen slowly,
but when moving quickly you can see discrete points at quite a distance
apart. Is there any way to get Qt to poll faster? Any other ideas for
getting better precision for mouse events? Thanks!
Josh
