With unintrusive error dialogs gone, we can cut some unnecessary bits
out of EActivity.
I'm also adding a new enum property called "state", which is one of:
E_ACTIVITY_RUNNING
E_ACTIVITY_WAITING
E_ACTIVITY_CANCELLED
E_ACTIVITY_COMPLETED
The state of an activity must be explicitly changed. In particular,
when the user cancels an activity the state should be set only after
confirming the operation has been cancelled and not when cancellation
is requested (e.g. after receiving a G_IO_ERROR_CANCELLED, not when
the GCancellable emits "cancelled"). EActivityBar and EActivityProxy
widgets have been updated to make this distinction clearer in the UI.
E_ACTIVITY_WAITING will be used when activities have to be queued and
dispatched in sequence, which I haven't written yet.
And generate GTypes for each of them in e-mail-enumtypes.[ch].
Also, the glib-gen.mak script forced me to add a <mail/e-mail.h>
top-level header, which really isn't a bad idea anyway.
TODO: We should do this for calendar and addressbook too.
This marks the end of unintrusive error dialogs, which were too
unintrusive. We now show errors directly in the main window using
the EAlert / EAlertSink framework.
'Send' and 'Save Draft' are now asynchronous and run outside of
Evolution's MailMsg infrastructure.
Add an EActivityBar to the composer window so these asynchronous
operations can be tracked and cancelled even in the absense of a main
window. Also add an EAlertBar to the composer window so error messages
can be shown directly in the window.
Instead of calling e_alert_dialog_run_for_args(), call e_alert_submit()
and pass the EMsgComposer as the widget argument. The EMsgComposer will
decide whether to show an EAlertDialog or use the EAlertBar, depending
on the GtkMessageType of the alert.
Global variables in shared libraries are a bad idea. EMailBackend now
owns the MailSession instance, which is actually now EMailSession.
Move the blocking utility functions in mail-tools.c to e-mail-session.c
and add asynchronous variants. Same approach as Camel.
Replace EMailReader.get_shell_backend() with EMailReader.get_backend(),
which returns an EMailBackend. Easier access to the EMailSession.
Rewrite the last usage of it in itip-formatter.c to use EAttachments
instead. This also allowed me to kill mail_save_part() in mail-ops.c.
I may need to reevaluate the EAttachment API at some point for all these
fringe EAttachment uses we're accumulating. Having to asynchronously
"load" an EAttachment whose content is already in memory kinda sucks.
In GTK+ 2.21.8, the keysym names were renamed from GDK_* to GDK_KEY_*.
I've added backward-compatibility macors to gtk-compat.h, which can be
dumped as soon as we require GTK+ >= 2.22.0.
All this time I never realized the subject-thread plugin was nothing
more than a stupid checkbox. The actual thread-by-subject code lives
in the core mail library.
If we're using GTK+ 2.21.8 (where gtk_dialog_set_has_separator() is
deprecated but the property is still present and defaults to TRUE), we
still need to set the property to FALSE. So instead use g_object_set()
up through GTK+ 2.90.6, after which the property itself is gone.
Unfortunately the default value for this property is TRUE (bzzt, WRONG!)
so we can't just remove the function outright until we require GTK+ 2.22.
It was deprecated in GTK+ 2.21.8.
