commit e64b96d316748d793e0acd24d3197e7e3df342b8
Author: Michael James Gratton <mike vee net>
Date: Sun Sep 25 22:53:34 2016 +1000
Split up handling of emails and composers in conversation list box.
* src/client/conversation-viewer/conversation-listbox.vala: Add two
different listbox child row types, one for emails only and one for
composers only, with a common ConversationRow superclass. When a draft
composer is added, replace the draft email it is standing in for, and
replace it again when removed. Rename last_email_row to last_row and
make into a generic ConversationRow, only update it at the end of a
batch of changes.
