[vishal.chauhan]

Hi All,

I m using Qt 4.2.2 on my Intel Mac.

I m using QListWidget in IconView Mode.
I am setting the Selection Mode to MultiSelction that is i can selct multiple Item by clicking on them.

But If i click and drag the mouse then It selcted many Items but I want that The multiselction would work only on mouse click not by Dragging mouse.

If anybody know how can I do it then plz help me.

Actually I can Implement the MouseMoveEvent in the form but I donot know how to implement it in the ListWidget.

The default implementation of QListWidget::mouseMoveEvent() does what you want to avoid. Therefore you must either subclass QListWidget and override mouseMoveEvent() with an empty implementation (just to avoid the base class from doing what it does by default) or alternatively install an event filter and filter the corresponding event out so that QListView implementation never receives the event.

But Actually I donot know how to subclass QListWidget from MainWindow class or some other class.

plz give some sample code for that if you can.

Thanks.
