Have a look at the setItemWidget function. You can design a widget (call it MyListItemWidget) that contains two icon labels and a text label, and in its constructor provide the two icons and the text. Then you could add it to your QListWidget. Sample code follows:

QIcon icon1, icon2; // Load them 
MyListItemWidget *myListItem = new MyListItemWidget(icon1, icon2, "Text between icons");
QListWidgetItem *item = new QListWidgetItem();
ui->listWidget->addItem(item);
ui->listWidget->setItemWidget(item, myListItem );

You should also take a look at QListView and QItemDelegate which is the best option for designing and displaying custom list items.

EDIT CONCERNING YOUR CONNECTION

When connecting a signal to a slot their signature should match. This means that a slot cannot have more parameters than a signal. From the signals-slots documentation

The signals and slots mechanism is type safe: The signature of a signal must match the signature of the receiving slot. (In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.)

This means that your signal must have the QListWidgetItem * argument in the connection.

connect(list, SIGNAL(itemClicked(QListWidgetItem *)), this, SLOT(clicked(QListWidgetItem *)))

I followed the same approach as suggested by you that works fine but after that when i use itemclicked event on the list it gets fired on double click , it should work on single click. – Territus

How do you handle the itemClicked signal? Some code would be helpful – Cheroot

Sorry I am using the same signature for SIGNAL & SLOT Copy paste Error :( – Territus

Have you debugged it? Are you sure that when a list item is clicked the slot is not called? – Cheroot

Just to add to you example: Also add this line item->setSizeHint(QSize(0,65)); , Otherwise the added item will not be visible, as it happened when i tried using your example. – Herren
