Passing a random GtkWidget and then searching its ancestors for an
EAlertSink turned out to be not as useful as I thought. Most of the
time we know about and have access to the widget that implements
EAlertSink, so just pass it directly as an EAlertSink.
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.
To reduce GConf usage in em-composer-utils.c:
- Relevant functions in em-composer-utils.c now take arguments for
reply and forward styles.
- Redundant forwarding functions were removed:
em_utils_forward_attached()
em_utils_forward_inline()
em_utils_forward_quoted()
- EMailReader now has "forward-style" and "reply-style" properties,
which get bound to the appropriate EShellSettings properties in
modules/mail/e-mail-config-reader.c. These same EShellSettings
properties are bound to the combo boxes in Composer Preferences.
So we don't have to access GConf directly from EMFolderTree. The
property gets bound to an EShellSettings property, which is in turn
bound to the "no_folder_dots" GConf key by way of a transform function.
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.
This module posts an alert to the first EShellWindow when starting
offline, and also posts an alert when the network connection drops.
We get frequent questions on the mailing list from users not realizing
Evolution is starting in offline mode, so this is meant to help address
that confusion.
You can now amend the predefined actions in an EAlert by calling
e_alert_add_action(). Useful for adding actions from an existing
GtkUIManager.
Call e_alert_peek_actions() to obtain a combined list of predefined
and custom actions. These will typically serve as "related" actions
for GtkButtons (cf. gtk_activatable_set_related_action()).
Also, both EShellWindow and EShellView now implement EAlertSink. Use
EShellWindow for application-wide alerts, EShellView for view-specific
alerts.
Listen for "prepare-for-quit" signals from the shell and inhibit
shutdown until all the activities we're tracking are finalized.
Also, add a couple supporting functions:
gboolean e_shell_backend_is_busy (EShellBackend *shell_backend);
void e_shell_backend_cancel_all (EShellBackend *shell_backend);
These will eventually replace mail_msg_active() and mail_cancel_all().
'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.
