Ok how do I do this? I figured if I used Extended selection mode and 
connected the selectionChanged signal this would be easy, but the 
selectionChanged signal is never emitted when in Extended mode. Next I tried 
connecting the currentChanged signal (staying with Multi selection) and using 
something like:

// Connected to currentChanged signal
void KMHeaders::highlightMessage(QListViewItem* lvi)
{
  if (!lvi)
    return;

  if (lvi->isSelected()) // (Really I need to know if the selection has       
                                 // changed, so this isn't quite right)
    // Update the message shown in the reader window
}

But lvi->isSelected is always false. (I mean when clicking on an item or when 
pressing the space bar after using ctrl-arrows to change the current item) I 
guess items are selected after the currentChanged signal is emitted.

Does that make sense? Using extended seleciton I don't see an easy way to 
only update the message shown in the readerwindow when the selection is 
changed.

(Note I did getting this working to my satisfacation by using my custom 
selection behaviour implemented in kmheaders.cpp and checked this in to cvs).

BFN,
Don.
