QStackedWidget fill Postscript image And scroll problem

[marcel]

Yes, and the code I've shown you should work just fine.
Isn't SplashOutputDev the widget in which you are rendering the current pdf page?
I assumed it was when I answered. Adding it to a scroll area and then adding the scroll area to the stacked widget will work.

You will not need any additional layouts or anything else...

Nice...

onepdf->SetPage(nowrender,QSize(doc->getPageWidth(nowrender),doc->getPageHeight(nowrender)));
src->setWidget(onepdf);
onepdf->setMinimumHeight(doc->getPageHeight(nowrender) + 1);
onepdf->setMinimumWidth(doc->getPageHeight(nowrender) + 50);
src->setBackgroundRole(QPalette::Dark);

onepdf->SetPage(nowrender,QSize(doc->getPageWidth(nowrender),doc->getPageHeight(nowrender)));
src->setWidget(onepdf);
onepdf->setMinimumHeight(doc->getPageHeight(nowrender) + 1);
onepdf->setMinimumWidth(doc->getPageHeight(nowrender) + 50);
src->setBackgroundRole(QPalette::Dark);

I thought that:

onepdf->SetPage(nowrender,QSize(doc->getPageWidth(nowrender),doc->getPageHeight(nowrender)));

onepdf->SetPage(nowrender,QSize(doc->getPageWidth(nowrender),doc->getPageHeight(nowrender)));

was already setting the size of onepdf.

EDIT:
Shouldn't you use:

onepdf->setMinimumHeight(doc->getPageWidth(nowrender) + 1);
onepdf->setMinimumWidth(doc->getPageHeight(nowrender) + 50);

onepdf->setMinimumHeight(doc->getPageWidth(nowrender) + 1);
onepdf->setMinimumWidth(doc->getPageHeight(nowrender) + 50);

You were setting page height for both minimum width and height.
