How to highlight items with ListViewer when mouse moves? [message #503312]

Hi,

I have a ListViewer that has a List of items, I want to highlight any item when mouse moves over it:

final List list = listViewer.getList();
list.addMouseMoveListener( new MouseMoveListener()
{
public void mouseMove( MouseEvent e )
{
Point pt = new Point( e.x, e.y );
//how to get the item on which mouse just moved over?
}
} );

The trouble is: either ListViewer or List has a getItem(Point p) implementation like Table.getItem(Point p). I am wondering if we have existing functionalities to achieve this?

thanks,

You say it would work with a TableViewer? Then change your ListViewer to
a 1-column TableViewer. It's more handy in general and a useful trick
to get around other ListViewer inconveniences.
