This commit does a number of things which I could not subdivide into
smaller commits.
* Converts ETreeModel to an interface, implemented by MessageList.
* Drops ETreeMemory and ETreeMemoryCallbacks, which were ETreeModel
subclasses. Their functionality is subsumed by MessageList.
* MessageList drops its public ETreeModel pointer, since MessageList
now implements ETreeModel as an interface.
* Adds message_list_set_expanded_default(), which takes over for
e_tree_memory_set_expanded_default().
This fixes a bug in the old implementation where the application could
crash after a second shell window was created and destroyed, because a
signal handler with the destroyed shell window as the closure was left
connected.
But moreover this simplifies the implementation by using a property
binding plus transform function instead of juggling signal handlers,
and also adds code comments where things get a little tricky.
Removed (now unused) functions:
e_shell_window_get_toolbar_new_prefer_item
e_shell_window_set_toolbar_new_prefer_item
Returns a GtkTreeModel of header names and values and visibility flags,
built from the CamelMimeMessage. The tree model rows can be reordered
and toggled prior to printing.
Also add e_mail_part_headers_is_default() as a handy helper.
This will replace the headers API in EMailFormatter. Need a more
permanent place for headers since EMailFormatter is too disposable.
Also add an ESettingsMailPartHeaders class, which binds the new property
to the "show-headers" setting with a suitable mapping function to filter
out disabled header names.
This is a weak reference to the EMailPartList to which the EMailPart
has been added. The property is set by e_mail_part_list_add_part().
New functions:
e_mail_part_ref_part_list()
e_mail_part_set_part_list()
The ESourceRegistry can still be obtained from the EClientCache:
client_cache = e_composer_header_table_ref_client_cache (table);
registry = e_client_cache_ref_registry (client_cache);
...
g_object_unref (client_cache);
g_object_unref (registry);
Added functions:
e_composer_header_table_ref_client_cache()
Removed functions:
e_composer_header_table_get_registry()
Reimplement EPhotoCache to delegate the actual photo fetching to
EPhotoSources. When a photo is requested for a given email address,
all available EPhotoSources are dispatched concurrently and a photo
input stream is selected from the result set.
This also utilizes EDataCapture, which is affixed to the returned
GInputStream to capture and cache photo data for an email address.
New functions:
e_photo_cache_add_photo_source()
e_photo_cache_list_photo_sources()
e_photo_cache_remove_photo_source()
e_photo_cache_add_photo()
Renamed functions:
e_photo_cache_remove() --> e_photo_cache_remove_photo()
EPhotoSource is an interface used to extend the functionality of
EPhotoCache. You can add an object implementing EPhotoSource to an
EPhotoCache with e_photo_cache_add_photo_source() and remove it with
e_photo_cache_remove_photo_source(). When EPhotoCache needs a photo
for an email address, it will invoke e_photo_source_get_photo() on all
available EPhotoSource objects simultaneously and select one photo.
EDataCapture is a GConverter that captures data until the end of the
input data is seen, then emits a "finished" signal with the captured
data in a GBytes instance.
When used with GConverterInputStream or GConverterOutputStream, an
EDataCapture can discreetly capture stream content for the purpose
of caching.
