<p>Hi, <br></p><p>I am using VTK with QT using QVtkWidget. Now <br></p><p>the problem is if i keep my
QmainWindow (which contains the QVTKWidget) without a layout, we see
that there are several problems including improper rendering and
transformations. <br></p><p><br></p><p>But as soon as i include layout, all those problems are
gone. <br></p><p><br></p><p>My question is What can be the issue here? My best guess is that
it must have something to do with Window to view port transformation and
in case of static (without layout) QVTKWidget, it does not update the
vieport transform. <br></p><p><br></p><p><br></p>
<p>Can it be the case ?
How can we calculate and set the Window->Viewport transformation in QVTKWidget ?</p><p><br></p><p>Regards,</p><p>Rashid<br></p>
