Size in pixels of string in QLabel

[Mankua]

Hello!

Is it possible to compute the width and height of the text in a QLabel? This size depends on the string contents and the font(s) used in QLabel.

I am adding a dynamic toolbar to my application, and all controls have a QLabel with the name of the tool, and then the control itself... for example:

Brightness: [ 0.0 ] Contrast: [ 0.0 ]

And I need to find the exact size in pixels of the "Brightness:" and "Contrast:" text as shown in screen to know how big my QLabel needs to be. Right now I'm doing this using trial and error.

Any ideas?

Thanks!

QFontMetrics will do it: http://doc.trolltech.com/latest/qfontmetrics.html

Example from that page:



QFont font("times", 24);
QFontMetrics fm(font);
int pixelsWide = fm.width("What's the width of this text?");
int pixelsHigh = fm.height();
