For Qt 4.6.x, how to auto-size text to fit in a specified width?
- by darenchow
Inside of my QGraphicsRectItem::paint(), I am trying to draw the name of the item within its rect(). However, for each of the different items, they can be of variable width and similarly names can be of variable length.
Currently I am starting with a maximum font size, checking if it fits and decrementing it until I find a font size that fits. So far, I haven't been able to find a quick and easy way to do this. Is there a better, or more efficient way to do this?
Thanks!
void checkFontSize(QPainter *painter, const QString& name) {
// check the font size - need a better algorithm... this could take awhile
while (painter->fontMetrics().width(name) > rect().width()) {
int newsize = painter->font().pointSize() - 1;
painter->setFont(QFont(painter->font().family(), newsize));
}
}
