Subject: Re: QTreeView setFirstColumnSpanned?

[Amit Chaudhuri]

...drawRow() idea as currently conceived in my mind doesn't work...It's
because it is a const method. This prevents setting a custom row delegate
to do the rendering.

QAbstractItemView - from which QTreeView derives - has a method which
allows us to set a delegate for any given row (specified by an int index
and giving a pointer to the delegate).

So, I think we can customise the text (etc.) in a given row, through a
simple custom delegate class, as long as we can specify "this row - index X
- is a trip row"
