Oh and you provide a model based solution. Much more elegant :)

Well i think the rule is that only top level windows are shown.
If a window has a parent,its not top level.
Some of it maybe due to the platform etc.
But is a flag if possible would be very nice :)

Thanks for your reply.
Yes retrieving the child model via child and then setting data worked for me .

Hi,

Isn't that pretty much the same question as here ?

@Chris-Kawa That's a valid point I hadn't considered. I'll just have to give this some more thought.

It seems like maybe the most "Qt-correct" design would be to override childEvent(QChildEvent* event) to take the pointer into the member object when a child is added to the parent object. This would then, at least, bypass the need to call "findChild" over and over again.

Compiled and rebuilt with Qt5.5.0 (beta). Unfortunately, the problem persists.
