[Qt 4.x] Highliting rows in a QTreeView

[Moppel]

Hi,

I want to highlight every other row in a QTreeView by changing the background colour for every ohter row.
|one |
|two|
|three|
|four|

I have done this in qt3 by reimplementing

QListViewItem::paintCell( QPainter *p, const QColorGroup &cg,
                  int column, int width, int alignment )

QListViewItem::paintCell( QPainter *p, const QColorGroup &cg,
                  int column, int width, int alignment )

To copy to clipboard, switch view to plain text mode 

I have a custom model which I feed into the view.

I just don't find an appropriate pointer where to do it.
In repaint of the view?
Or do I have to use a custom style?

Thanks,

Moppel

try myTreeView->setAlternatingRowColors(true);

cool, that works! Completely missed that in the doc. Embarrassing!
Thanks.
Seems to have been a so often reimplemented feature that the trolls put it in there API then.

Right, but now, if I want to go further and highlight a row or a even a cell depending on the content of the row/cell.
How can I do this?

Use different roles from the model. If it's not enough, provide a custom delegate for the view.
