</span>Basically the modeltester tries to check if the model behaves correctly<br>
with whatever it does. It can test quite a few things without any<br>
modifications to the model, but ideally you should start the modeltester<br>
and then do various modifications to the model. In my code, I have<br>
various test cases for the model, and simply also activate the<br>
modeltester for all of them.<br>

Some comments about the code below:<br>

</span>Wouldn't it be easier to just use a QStandardItemModel with<br>
QStandardItems?<br>

This seems wrong, your leaf items dont have any children.<br>
