multiple exported interfaces in one plugin - how to?

It is stated in the documentation for Q_EXPORT_PLUGIN2 macro:

Quote:

There should be exactly one occurrence of this macro in the source code for a Qt plugin

.
My questions are:
1. Is it possible to export more then one class in a single plugin?
2. If yes then how it should be done?

Thanks.

You can export a plugin that will be an interface to more than one class. QDesignerCustomWidgetCollectionInterface is an example of such approach.
