Since i did most of this stuff i should attend the meeting as well = =3D)
Good for me is between 20.00- 24.00 GMT+1, today for instance would be
good.

The layout recreation is a workaround since the QGraphicsGridLayout
doesn't remove the items properly.
I think Aaron and Marco agreed on this workaround an we will have to keep it that way until it's fixed in QT.

If the problem is in Qt then i will fix it, it's = my job. And removing items should work and must work...
I have already u= sed QGraphicsGridLayout and it should work as far as i know and the last ti= me i used it.
Anyway if the bug exist why don't you write to the support of Qt Softwa= re about that?
I have actually screen all QGraphicsLayout tasks and ther= e are no such of things. So the bug will never be fixed if it exist.

Anyway i will take a look at it...

Christian
