Displaying QAbstractItemModel in a Table

[bmesing]

Hello

I have a hierarchical QAbstractItemModel. For this model, I want to display all the items which are not at the top level in a simple list.

The Model:

parent1
+- child11
+- child12
parent2
+- child21
parent3
+- child31

parent1
+- child11
+- child12
parent2
+- child21
parent3
+- child31

To copy to clipboard, switch view to plain text mode 

should be displayed as:

child11
child12
child21
child31

child11
child12
child21
child31

To copy to clipboard, switch view to plain text mode 

I have tried to accomplish this by displaying the model in a QTableView, but this displays only the parent items. I have also tried to display the model in a QTreeView and hiding the parents, but unfortunately hiding the parent items does also hide their children.

Is there a way to do this except for writing a completly new view class? Perhaps subclassing QTreeView or QTableView in a smart way?

Any help would be appreciated.

Try implementing a proxy model. There's an example of a Transpose Proxy Model in our wiki. It doesn't do at all what you want but gives you a simple idea how proxy models are implemented. What you should do is to map the children as top level indices.
