[Interest] QInputDialog as item delegate?

[Matthew Woehlke]

I have a QTreeView. For one of the columns, rather than editing the data
in-place, I want to pop up a QTextEdit. (For now, I'm hoping I'll be
able to use QInputDialog, but I may end up needing to roll my own.)

Is it reasonable to execute the dialog (QDialog::exec()) in an override
of QAbstractItemDelegate::createEditor, or do I need to hook
itemActivated or some such? (Maybe QAbstractItemDelegate::editorEvent
would be better?)

What is the best way to trigger the editor?
