Better behaved previews

Hi all,

After committing the smooth previews patch to trunk/kdelibs I felt like I had 
to improve it. Here is the patch. I ask for confirmation for committing.

Apart from making it slightly better (it won't try to clear what is already 
cleared), it is very nice to see:

- Navigate to an item with keyboard: as you move, the current index preview is 

- Hover an element: its preview is triggered (we give more preference to the 
hover events).

- Unhover the element and go to the blank part of the view: the current index 
preview is triggered again ! (if there were no current index selected, then 
the last hovered element is kept, this is specially good when previsualizing 
videos, because you can go to the control bar of it).

- Clear selection by clicking on the blank part of the view: preview gone.

So the main change is that when you have a selection with current index and 
you unhover an element, the preview of the current index is triggered back.

Anyway, I suggest you to test it in order to see it actually working.

OK to commit ?

Bye and thanks, 
Rafael Fernández López
