Hi.
I've encountered a strange behaviour of the (trackball) navigator. When
attaching a (passive)viewport which fills the entire PassiveWindow
everything works fine. If using a viewport which only fills the lower
left quadrant of the window, the behaviour of the navigator gets messed up:
Rotation around the X-axis works fine.
Rotation around the Z-axis works as if the viewport took up the whole
window.
Rotation around the Y-axis is somehow only possible around the center of
the upper left quadrant of the window.
I'm using a QGlWidget which has (0,0) in the upper left corner. I've
tried to transform these into (0,0) in the lower right corner, but got
the same behaviuor.
Do I somehow need to tell the navigator the center of it's coordinate
system, or is there a special transformation need to do?
