I have been working for sometime (few weeks) with the Designer. It is very useful when you get its tricks, although I still have some confusion about sizes,resize and size policies. But that is not the point of this thread.
I had to make some plugins, and I read documentation examples. My plugins work fine, but I have some questions about container plugins. Lets say I have a plugin that is just a widget with 2 group boxes in an horizontal layout. I make a plugin with that, returning yes in isContainer, of course, then , how do I put, for example, a label in a layout in the first group box? Can I do that? Is the whole plugin is just like one widget and I cant reffer just to one of its components?
It would be really,really,really useful to me. I miss more detailed examples to make it easier to see all (or at least more) of the Designer and its plugins power.

Thank you very much.
