[Qt-interest] Is there any mapping mode support in Qt Graphics Framework to map logical co-ordinates to physical co-ordinates

[Mihail Naydenov]

I think not in a straightforward way. You can access the screen in pixels, then 
you can try to query the QPaintDevice::physical/logicalDpi (QWidget is a 
paintDevice, so try to query the graphics scene view's viewport() widget for 
these)
and compute real word coords.

PS I just noticed you want to *control* the dpi... I dont think it is possible, 
reading the docs for QPaintDevice the metrics are read only it seems...
