[Qt-interest] Other trouble with QPrintPreviewWidget

[Marcelo Estanislau Geyer]

Hi David and Friends,

I'm having another problem and believe that may be another bug. Still
using QPrinter: HighResolution to resolve the problems earlier. 
 I'm creating a report and use QFontMetrics::height to get the
information from the height of the font that I am using to use as the
distance between the rows of my report. But the information is
returned to 11px this code:



QFont font;
font.setFamily("Sans");
font.setPointSize(5);
painter.setFont(font);

QFontMetrics fontMt(font);
qDebug() << "Font pixel: " << fontMt.height(); // This values is 11px! 
 There is something wrong with that. It should be much higher because of the resolution that I am using.
Thanks,
