Using the Qt framework, how do I measure the width (in pixels) of a piece of text rendered with a given font/style?

Since Qt 5.11 you must use horizontalAdvance() method of QFontMetrics class instead of width(). width() is now obselete.
QFont myFont(fontName, fontSize);;
QString str("I wonder how wide this is?");
QFontMetrics fm(myFont);
int width=fm.horizontalAdvance(str);
