What is meant by logical cordinates and physical cordinates in Graphics View Framework terminology ?

[Keshav Sharma]

I've been reading few books on Qt but couldn't understand what exactly does it mean when author cites coordinates as logical or physical, is there any difference as to from where origin (0,0) start in both of these ?

Hi,

Have you read the Coordinate System chapter of Qt's documentation ? It's explained there.
