Using resource DLL in designer.

Hi.

I have successfully made a dll with some widget as plugin to designer.

The same DLL includes icons with the qrc file.

When I write a small program that creates a mainWindow and uses my widgets I can use the icons "normally" as ":commonResources/ok.png"

How do I make the resources from in the dll available to designer, so I can use them while designing new pages ???

I have tried to load the icon as a file giving ":commonResources/ok.png" but designer complains it is not a valid file (which of course are correct).

thanks in advance for any help.
