gramps/gramps2/src/plugins/ScratchPad.py
Richard Taylor 0b5eeddbd1 2005-03-25 Richard Taylor <rjt-gramps@thegrindstone.me.uk> 
* src/ScratchPad.py (ScratchPadWindow): moved content of pad to a
	class attribute so that it is preserved when the pad is closed.
	* src/ScratchPad.py (add_itself_to_menu, remove_itself_from_menu):
	removed large section of commented code.

class ScratchPadWindow:
"""
The ScratchPad provides a temporary area to hold objects that can
be reused accross multiple Person records. The pad provides a window
onto which objects can be dropped and then dragged into new Person
dialogs. The objects are stored as the pickles that are built by the
origininating widget. The objects are only unpickled in order to
provide the text in the display.
No attempt is made to ensure that any references contained within
the pickles are valid. Because the pad extends the life time of drag
and drop objects, it is possible that references that were valid
when an object is copied to the pad are invalid by the time they
are dragged to a new Person. For this reason, using the pad places
a responsibility on all '_drag_data_received' methods to check the
references of objects before attempting to use them.
