[Qt-interest] Trouble with QPrintPreviewWidget

[Marcelo Estanislau Geyer]

David,

I understand perfectly that there may be differences between the
systems. Passing QPrinter: HighResolution in constructor
QPrinter got a satisfactory result. 
 These results:
pageRect: QRect(0,0 9917x14033)
logicalDpiX and logicalDpiY: 1200

The values is refer in the same notebooks (kubuntu in 1440x900 and Fedora in 1024x768).
The paperSize is A4.  

As the report is that I am generating complex, I have some special care? I could have surprises in future?
I thought of designing the rectangle with fixed values based on the resolution currently supported (Logical DPI)

Thanks,

Marcelo.
