For Qt 4.6.x, how to auto-size text to fit in a specified width?

Hi there!

Two days ago I solved it with QFont::setPointSizeF like this:

float factor = rect().width() / painter->fontMetrics().width(name);
 if ((factor < 1) || (factor > 1.25))
 {
  QFont f = painter->font();
  f.setPointSizeF(f.pointSizeF()*factor);
  painter->setFont(f);
 }

float factor = rect().width() / painter->fontMetrics().width(name);
 if ((factor < 1) || (factor > 1.25))
 {
  QFont f = painter->font();
  f.setPointSizeF(f.pointSizeF()*factor);
  painter->setFont(f);
 }

To copy to clipboard, switch view to plain text mode 

This assumes, that your fonts width scales like its height. Works fine for me.

HIH
