That would be the ideal solution: point the widget's stylesheet to a
file, instead of the text, but...

Since my custom widgets were a subclass anyway, I created a Designer
extension to such subclasses. Is very easy, and you just have to write
some boilerplate. If you are not already doing it, you can load the
stylesheets through QResources, so the Designer extension has the
styles built in. If you are not doing it and you don't want/can't do
it, you can add some #ifdef that check if QDESIGNER_EXPORT_WIDGETS is
defined, and use QResources only there.
Let us know if you need more info.
