[Qt-jambi-interest] [Qt Jambi 4.4] Can't addVideoPlayerto graphics view (scene)

[Dimitri Frederickx]

I've removed the line:
videoPlayer.setParent(.....

But removing this line still generate the error:
GraphicsProxyWidget::setWidget: cannot embed widget 0x1ec1b6e0 that is not a 
window

But I will wait for a newer version of Qt Jambi in which I can add a VideoWidget to a 
graphics view. When the problem then still occurs in that version I will bother you 
again ;-)

Since there are no snapshots available of Qt Jambi like there are for Qt, will it for 
example be possible to publish weekly builds of 4.4 with the latest bugfixes?
