[Sugar-devel] [write v2 PATCH] sl#4442: Now, Copy-to-Clipboard works fine, after the recipient clicks on the thumbnail, and the complete-data isfetched.

[Ajay Garg]

=======================================

v1 -> v2 ::
==========

Added the explanation of the fix.

=======================================


Initially, the bug was due to the fact that the thumbnail-palette was initiated just once (when the 
thumbnail was first created). 

Now, when the thumbnail is first created for a "received" thumbnail, initially no "Copy to Clipboard" option is
shown. However, after the user clicks the thumbnail and the data is fetched, the  option is shown.

At code level, every time the user hovers over the thumbnail, the "expose-event" signal is emitted, thereby calling the 
"do_expose_event" method. As the fix, we override this method, first checking to see if the data has been fetched for 
the thumbnail. If yes, we add the "Copy to Clipboard" option in the palette, and mark a flag for the same, so that it
is not re-added on subsequent "expose-event" signal.
