Review request for KDE Edu, David Narváez and Rex Dieter.

Repository: kig


Description
-------

QRect object in qt uses integers.  This causes annoying loss of drawing precision when drawing circles (https://bugs.kde.org/show_bug.cgi?id=359805).  Using the QRectF object seems more appropriate.


Diffs

  misc/kigpainter.h e36c153 
  misc/kigpainter.cpp e547bf2 
  misc/screeninfo.h b7f94c4 
  misc/screeninfo.cc 8fdf115 

Diff: https://git.reviewboard.kde.org/r/127354/diff/


Testing
-------

This is a minimal patch to allow using QRectF when drawing circles.  Perhaps using QRect
(and QPoint) could be dropped completely in favour of QRectF and QPointF.


Thanks,

Maurizio Paolini
