[Qt-interest] QUiLoader and promoting widgets in QtDesigner

[Martin]

Hi all,

is there any way to use promoted widgets in .ui-files loaded with QUiLoader? 
Or do I have to build a plugin for QtDesigner? The error message I get is:
"QFormBuilder was unable to create a custom widget of the class 'x::y::ZView'; 
defaulting to base class 'QWidget'."

Regards,
Martin
