QPageSetupDialog QT open 'empty' window on QT5

[creatron]

I am using a table printer class for many moons, however the QPageSetupDialog creates a empty window when ported to QT5, if compiled with any version < 5 (4.5, 4.6, 4.7 4.8) it actually works.

I created a test program to verify the problem with abs minimal code.

Tested on Ubuntu 13.04 (64Bit), using the 'default' and downloaded version 5.1.0 SDK (Creator 2.7.2)

What else must be changed to get a printer setup window in QT5?

Thanks

Hi,

This sounds like a regression. You can check the "bug report system":bugreports.qt-project.org/issues/ to see if someone else already reported it.
