Package: libqtcore4
Version: 4:4.8.6+git64-g5dc8b2b+dfsg-2+b1
Severity: normal
Hello,
I've been hit by a bug where I have essentially this: (ret is QRectF)
ret.setTop(0.1);
ret.setBottom(-0.1);
o << "Fxd: " << ret.height() << " -> " << ret.top() << " | "
<< ret.bottom() << endl;
The output line shows that, if you have a NaN in the coordinates,
then the line above DOES NOT set the top and bottom coordinates
(they stay at NaN):
Fxd: nan -> nan | nan
Looking at the code for setTop, it all makes sense, as the pro
inline void QRectF::setTop(qreal pos) { qreal diff = pos - yp; yp +=
diff; h -= diff; }
However, this is very confusing at best... Looking at the
documentation, calling moveTop and then setBottom may be smarter,
but, it really should just work...
Best regards,
Vincent
