All this so EMFolderTree can submit EActivity instances for async ops.
You can obtain an EMailSession from an EMailBackend, but not vice versa.
Creates lots of pretty ripples in the mail code, but ultimately reduces
complexity. So it's a code cleanup of sorts.
Add an action group for Search Folders to EMailReader. The action
group's visibility is bound to the "mail-enable-search-folders" setting,
so that menu items related to Search Folders are hidden when Search
Folders are disabled in GConf.
Affected menu items are:
Edit -> Search Folders
Message -> Create Rule -> Search Folder from Subject...
Message -> Create Rule -> Search Folder from Sender...
Message -> Create Rule -> Search Folder from Recipients...
Message -> Create Rule -> Search Folder from Mailing List...
Search -> Create Search Folder From Search...
Use an enum type to request different action groups. For now we just
have E_MAIL_READER_ACTION_GROUP_STANDARD. EMailReader implementations
should map the enum value to an appropriate GtkActionGroup.
This starts up the EMailShellBackend whenever a new composer window is
created. Normally this happens when switching to the Mail shell view,
but if trying to send a message from a different shell view before the
Mail shell view is ever activated, the mail accounts were not getting
loaded and sending or saving the message to a mail folder would fail.
Configuring and submitting an EActivity for every mail operation is
getting tedious. This function helps reduce boilerplate code by:
* Creating a new EActivity instance.
* Installing an EAlertSink using e_mail_reader_get_alert_sink().
* Installing a GCancellable (which is really a CamelOperation).
* Submitting the activity via e_shell_backend_add_activity().
I'm considering adding a similar function (or class method) for
EShellView. Not sure yet...
Convenience function for use in GAsyncReadyCallback functions.
This acknowledges the cancellation, so that the activity's description
changes from "(cancelling)" to "(cancelled)" and the description appears
crossed out in the UI for a moment before disappearing.
This one's a little involved:
- EMailShellView now obtains a CamelFolder itself in response to
EMFolderTree::folder-selected signals. Uses EActivity to do so.
- Revise EMFolderTree::folder-selected signal arguments to be more
useful: emit a CamelStore object instead of a folder URI.
- Also revise EMFolderTree::folder-activiated signal arguments the
same way while we're at it.
- Remove the "folder_uri" argument from e_mail_reader_set_folder().
If you have a CamelFolder object you can obtain the URI string by
calling camel_folder_get_uri().
With lockdown settings available through GSettings, widgets can handle
lockdown integration themselves without having to use EShellSettings.
Also fixed a few places where printing or save-to-disk actions were
either not properly wired up or not responding to lockdown settings,
but much more work needs done. Attachments, for example, are not
honoring the disable-save-to-disk setting at all.
This too requires the recently-added gsettings-desktop-schemas
dependency.
