The simplest idea I can think of is to implement a simple proxy model that will add three fake top-level items and serve their children from real models. Shouldn't be more than 30 lines of code...

I'm facing a problem

in mapFromSource() the parameter 'index', i don't seem to be able to identify which source it is from. so that when i mapToSource() i will send it back to the correct source.

You have three models so reimplementing mapFromSource() is not enough.

It would be cool to get more detail on this topic...
