Replacement of Images

[merry]

HiHi all

I am using Qt3.1 for Linux Operating System.

My Problem is that how can I replace one image with another,

By using Connections(Signals and Slots)

connect(listView,SIGNAL(pressed(QListViewItem*)),t his,SLOT(reverse_images(QListViewItem*)));

it can replace images.

But what I want is after replacing images when I pressed again on an item it can again replace image with the first one(initial one).

Pls do reply with an eg.

Thanx and Regards
