Actually, it is fired when the row is "activated", which is gtk+  
lingo for "the user double-clicked with the mouse or hit 'enter'  
while keyboard focus was in the widget".

"cursor-changed" tells you that the keyboard focus cursor has moved  
from one cell to another, including a new column in the same row.   
There's also the situation that "special" cells don't cause the  
signal to fire (according to the gtk+ source).

The "changed" event on the TreeView's selection tells you that the  
selection has changed.  If your tree is in single-selection mode,  
this is most likely what you want.

If you need something more specific than that, e.g. to pop up a  
context menu, then you'll be working with button-press-event  
directly.  Hint: use signal_connect_after() for button-press-event on  
TreeView or strange things tend to happen.
