I see icons on most menu's, see attached...
Hmmm...

Not here, no icons anywhere, although the QT4 apps shows them all.
Any ideas what to look at?
Do I perhaps have some sort of QT5 component missing/miss-configured you think???
EDIT
====So I only had the qt5-qtbase.pentium4 RPM installed...looking at what's out there I realized that there were numerous other QT5 RPMs, some like qt5-qtmultimedia or even qt5-qtsvg could be playing a role here.
Needless to say, off I went to install qt5 RPM, which in turn pulled in what I presume is the full combination of QT5 implementation RPMs.
End result => icons do now show! (so there is probably another QT5 package that is needed and which is not currently shown in qpdfview's 'install.os2' file).
