[Qgis-developer] QGIS Custom Widget in Qt Designer

[Marco Bernasocchi]

Hi Denis, 
I was just put of by the fact that the xml tag is called customwidget.

They are in fact promotet widgets. And I really wonder how this can work.

Could you try the resource sharing plugin. Does it work for you?

Ciao
