Hi hesummar:

I have a similar problem in qt 3.3.4 with designer 3.3.4. Even when the path was added with qtconfig, and apparently accepted by designer, my plugins did'nt work.

I found out that, at least with my version of qt, if the plugin lib was in a directory different from the one in qt3 tree (/usr/lib/qt3/plugins/designer/), the plugin was not recognized by designer.

¿Have you tried puting the plugin in that directory?

Bye.
