commit 64aa037c045f308397fd9ad08e959983aa22bd47
Author: Michael James Gratton <mike vee net>
Date: Sat Apr 9 17:32:29 2016 +1000
Add new ConversationMessage widget to display a single message with a WebView.
The new widget is designed to be added to a ListBox like container, and
can display both a summary and the complete message, a'la the traditional
Geary ConversationView.
Most features are currently disabled, but it does handle hiding/showing
the message body using a single WebKit.WebView. All code from
ConversationViewer relating to DOM manipulation as been copied over, all
but that which was needed to display the message has been commentd out.
* src/client/conversation-viewer/conversation-message.vala: Source code
for new widget.
* src/client/components/main-window.vala: Add CSS theme code for
ConversationMessage.
* ui/conversation-message.ui: GtkBuilder template for new widget.
* ui/conversation-message-menu.ui: GtkBuilder for the message menu. This
is a separate file since GTK+ 3.10 doesn't support GtkPopoverMenu and I
can't build it using Glade otherwise.
* src/CMakeLists.txt: Added new source file.
* po/POTFILES.in, ui/CMakeLists.txt: Added new UI files.
