class MessageTreeWidget:

"""
|
|
This widget displays an ElementSupply, including user interface like a
|
|
cursor or folding markers. It usually is part of a RoomWidget. It also
|
|
keeps a RenderedMessageCache (and maybe even other caches).
|
|
|
|
It receives key presses and mouse clicks from its parent widget. It
|
|
receives redraw requests and cache invalidation notices from the
|
|
RoomWidget.
|
|
|
|
It doesn't directly receive new messages. Rather, the RoomWidget adds them
|
|
to the ElementSupply and then submits a cache invalidation notice and a
|
|
redraw request.
|
|
|
|
It emits a "room top hit" event (unnamed as of yet). When the RoomWidget
|
|
receives this event, it should retrieve more messages from the server.
|
|
|
|
It emits a "edit" event (unnamed as of yet) when the user attempts to edit
|
|
a message. When the RoomWidget receives this event, it should open a text
|
|
editor to compose a new message, and send that message once the user
|
|
finishes editing it.
