QTreeView with Model-View help

[MathStuf]

Hi,

I am trying to make a tree for my data objects, but I am having trouble figuring out how I should approach it to make it as clean as possible. I was using a QTreeWidget, but it felt very hackish and wasn't very nice to keep up with. I'd like to use a QTreeView, but I am unsure of how to handle the models. An example of how my data classes work is below.

• data class 1
  
  • group
    
    • sub-data class 1
      
      • group
        
        • sub-sub-data class 1
  • group
  • group
• data class 2
  
  • group
  • group
  • group

At the root, there are the large data classes, then there are groups of related data classes within that (the groups keep unrelated data classes from grouping together). When a data class is added, it needs to build its subtree of data and groups. the group "labels" cant be selected, but the data classes each have a widget for editing the internal data. How should I design the model to handle this?
