My team has been work­ing on port­ing some PyQt stuff to Mac OS­X, and we have run in­to sev­er­al Qt bugs, sad­ly. Here are two, and the work­arounds we found.

Na­tive di­alogs are bro­ken.

Us­ing QFile­Di­a­log.ge­tEx­ist­ingDi­rec­to­ry we no­ticed the fol­low­ing symp­tom­s:

• If you do noth­ing, the di­a­log went away on its own af­ter about 20 sec­ond­s.

• Af­ter you used it on­ce, it may pop up and dis­­ap­­pear im­me­di­ate­­ly. Or not.

So­lu­tion: use the Don­tUse­N­a­tive­Di­a­log op­tion.

Wid­gets in QTreeWid­getItems don't scrol­l.

When you use Wid­gets in­side the items of a QTreeWid­get (which I know, is not a com­mon case, but hey, it hap­pen­s), the wid­gets don't scroll with the item­s.

Solution: use the -graph­ic­ssys­tem raster options. You can even inject them into argv if the platform is darwin.
