Promote widget to custom with preview in designer

[ThaRez]

Hello
I'm wondering it it's possible to display a preview of the custom class when promoting a widget?
E.g. I I make a widget consisting of standard components, let's say two pushbuttons, can I have
the Qt creator (design mode) displaying this when promoting a widget to this custom class?
Best regards
Richard
