QPainter::drawText and QFont::setStretch
Message 1 in thread
I'm trying to fit a small text string in a given rectangle.
To get it to fit, I am trying to use QFont::setStretch(), but it has
no effect.
QRect dayBox....
QPainter painter....
QFont foo = painter.font() ;
foo.setPixelSize ( dayBox.height() ) ;
foo.setStretch ( 25 ) ;
int textWidthInPixels = fm.width("00");
if ( textWidthInPixels > ( dayBox.width() )
{
foo.setStretch ( ( 100 * dayBox.width() ) / textWidthInPixels ) ;
}
painter.setFont ( foo ) ;
painter.drawText ( dayBox, Qt::AlignVCenter|Qt::AlignHCenter, "00") ;
Is this a known problem or what ?

Never mind.
I was using 4.2, so I tried 4.3 and the problem went away.
