background color for each list view item

Hi,
How do i set the background color of a list view item in a list view using paint cell function?
I have overridden paintcell function of QListviewItem.
i have to change the background color of the listview items in an alternate fashion..i.e green- yelow- green- yellow..etc..

Thanks in advance, :D
Veena.

You can check the listview examples that come with QT. There it only changes the color of the text for unread items but the concept is the same.

It is something like
[code:1]
void <something>&#58;&#58;paintCell&#40; QPainter *p, const QColorGroup &cg,
int column, int width, int alignment &#41;
&#123;
QColorGroup _cg&#40; cg &#41;;
QColor c = _cg.background&#40;&#41;;

if &#40;<some count> % 2&#41;
_cg.setColor&#40; QColorGroup&#58;&#58;Background, Qt&#58;&#58;lightGray &#41;;

QListViewItem&#58;&#58;paintCell&#40; p, _cg, column, width, alignment &#41;;

_cg.setColor&#40; QColorGroup&#58;&#58;Background, c &#41;;
&#125;
[/code:1]

use KListView and KListViewItem

The KDE classes supports that out of the box, and even uses the colors configured by the user.
