New Article

I don't know for how long it has been available on-line, but I wrote another article for Qt Quarterly. For your reading pleasure: Designing Delegates.

Nice and technical article. I appreciated it a lot. However I think you're leaking your model. Probably want to have it as a child of the dialog and let Qt free it for you:

void TreeDialog::populateTree()
- QStandardItemModel *model = new QStandardItemModel();
+ QStandardItemModel *model = new QStandardItemModel( this );

QStandardItem *parentItem = model->invisibleRootItem();
for( int i=0; i<4; ++i)

Only a tiny 9K in your example, but could be more in real life :)

Of course, you're right. Sorry about that. My mind got sucked into some sort of the-view-takes-ownership-of-the-model-idea...
