commit b6c357d66a44d2ce666c7e153a7709f72db0b7a9
Author: Michael James Gratton <mike vee net>
Date: Mon Jul 25 10:33:42 2016 +1000
Break out ListBox used to display conversations into standalone widget.
The conversation viewer's ListBox is sufficiently complex to warrant its
own widget. Use empty placeholders for the list per the HIG, and
correctly fix mamagement of empty folder vs no conversations selected
this time.
* src/client/application/geary-controller.vala (GearyController):
Directly manage secondary parts of the conversation viewer, since the
controller since it has a better and more timely idea of when a
conversation change is due to folder loading status or from the user
selecting conversations, and so the viwer doesn't need to hook back
into the controller. Remove the now-unused conversations_selected
signal and its callers.
* src/client/conversation-viewer/conversation-listbox.vala: New widget
for displaying the list of emails for a conversation. Moved relevant
code from ConversationViewer here. Made adding emails async to get
better UI responsiveness. Don't implement anything to handle
conversation changes or emptying the list.
* src/client/conversation-viewer/conversation-viewer.vala: Replace user
messages - empty folder/search & no/multiple messages selected with new
EmptyPlaceholder. Remove a lot of the state manage code needed when
managing the email listbox. Add a new ConversationListBox for every new
conversation and just throw away.
* src/client/conversation-list/conversation-list-view.vala
(ConversationListView): Clean up firing the conversations_selected
signal - don't actually emit it when the model is clearing, and don't
bother delaying the check either.
* src/client/components/empty-placeholder.vala: New widget for displaying
empty list and grid placeholders per the HIG.
* src/client/conversation-viewer/conversation-email.vala
(ConversationEmail): Make manually read a property, since it
effectively is one.
* src/CMakeLists.txt: Include new source files.
* po/POTFILES.in: Include new source and UI files, and some missing ones.
* ui/CMakeLists.txt: Include new UI files.
* ui/conversation-viewer.ui: Replace user message and splash page with
placeholders for the new empty placeholders(!).
* ui/empty-placeholder.ui: UI def for new widget class.
* ui/geary.css: Chase widget name/class changes, style new
empty placeholder UI.

- * In addition to the email list, docked composers, a progress spinner
