Hi Srini,
thanks for the details but I'm not using QGraphicsView.
This is a custom Widget with a stacked layout, that slides the old
widgets out of frame and the new ones in.
I'm thinking something like this might be what I need to collect and add
to the widgets' position to get their true positional values (so the
animation won't stutter):
self.style().pixelMetric( QStyle.PM_DefaultFrameWidth )

As you are asking about animation, I am assuming you are
using QtGui.QGraphicsView.
Working with QGraphicsView, I found following few key things related
to size/coordinates.
1. By default QtGui.QGraphicsView aligns the scene to center. So all
resizes are set wrt center. To change the anchoring back to top, use
following.
setAlignment(QtCore.Qt.AlignTop)
2. If you are trying to get resizable scene, you may want to
use resizeEvent of QtGui.QGraphicsView and adjust your widgets/layouts.
3. Have a default screen size so that widget reference starting point
is something you can always control. You could also do relative
distances based on the screen size - but it is some more
initialization that you need to take care of.
Hope above is what you are looking for.
thanks

Hi everyone,
I am trying to learn what inherited value may contribute to a widget's
real screen position.
In my example I have a widget that I am animating out of frame, so I
need to determine exactly what it's static position is to be able
to set
that as the animation's start value. If I just use QWidget.pos().x() I
am 5 pixels off. So currently I'm just adding 5 pixels manually, but
would love to understand where those come from and how to
calculate the
widget's position properly and reliably.
Any ideas anyone?
Cheers,
frank
