QTreeWidgetItem::setHidden() painfully slow

Message 1 in thread

Hi all,

i have just found out that calling setHidden on a couple of QTreeWidgetItems 
is very slow.

Calling removeChild() and addChild() instead of setHidden() is magnitudes 
faster. Instead of several seconds it happens in an instant.

Anybody else experienced this?

Regards
.....Volker

(answering my own post :-)

I see this issue has already been discussed on the list.
And there seems to be a fix in qt4.3.3
