commit a4453657f36f8f5acf6287bcd2903a0afe7ae3c5
Author: Michael James Gratton <mike vee net>
Date: Sat Jan 14 22:34:48 2017 +1100
Re-enable inserting inline images in the composer.
* src/client/components/client-web-view.vala (ClientWebView): Remove
now-unsed ;;allow_prefix property. Add ::insert_image method.
* src/client/composer/composer-widget.vala (ComposerWidget): Split up
"attachment" handling into inline and attached parts so we can require
a Content ID be passed in for inline parts. Convert ::inline_files set
into a map, so we can be explict about the IMG SRC URL that was used to
refer to the inline part, either cid or geary, and update call sites.
(ComposerWidget::on_insert_image): Simply add the image as a new inline
part with a geary URL, and insert it via the editor.
* src/engine/api/geary-composed-email.vala (ComposedEmail): Also use a
map of inline parts, for the same reason as ComposerWidget. Update call
sites.
* src/engine/rfc822/rfc822-message.vala (Message.from_composed_email):
Use the given URL for inline parts when assigning Content IDs and
replacing the internal URL in the source.
