multiple models in a single view
Message 1 in thread
Hello,
Has anyone have an idea on how to display multiple models in a single view?
I know it sounds bizare, but I would like to have a QTreeView, and have a
number of models displayed one after another.
They only other way I can think is to us separate views for each model, but
then they all end up with separate scrollbars etc which is not really what
I want.
Thanks

Not sure what you mean with the tree view..
But I have had it on a tree view...
I created a custom model derived from a proxy model.. which using hasa
relationships, owned multiple models.
Essentially, the custom model was a would return the correct
ModelIndexes that would allow the system to have each top level node
return the correct info into the correct sub model...
It wasn't easy.. but I did get it working in about 1-2 days work

I thought of this idea, creating my own model to aggregate other models
together, but it looked kinda annoying to implement so I was hoping there
was some easy way of doing it.
