Qt Designer plugin.. no drag and drop icon bellow cursor

[Dwarf007]

Hi,

I created a Qt Designer plugin and it was added correctly to the widget list in Qt Designer.
But when I want to drag it to the main window there is nothing happening.. no icon/picture bellow the cursor..

As my plugin is derived from QLineEdit, I was expecting to see a QLineEdit when draging my plugin.

Anyone knows how I can resolve this ?
Cheers,

Daniel
