If a newly-composed message was successfully sent but an error occurred
during post-processing (outgoing filters or appending to a Sent folder),
close the composer window and show an alert in the main window.
This is just for convenience, EActivity does not use this property.
Especially useful in async function callbacks when the operation
failed and now you have to do something useful with the GError.
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.
When sending a message from a composer window, it seems pointless to
write message to Outbox only to immediately read it back and mark it
for deletion. Instead, bypass the Outbox folder when sending, and if
an error occurs, offer to save the message to Outbox instead.
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.
'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.
Trying out a new interface called EAlertSink. The idea is to centralize
how errors are shown to the user. A GtkWindow subclass would implement
the EAlertSink interface, which consists of a single method:
void (*submit_alert) (EAlertSink *alert_sink, EAlert *alert);
The subclass has complete control over what to do with the EAlert,
although I imagine we'll wind up implementing various alert-handling
policies as standalone widgets such as EAlertDialog. I'd like to try
an EAlertInfoBar.
Code that would otherwise display an error dialog itself would instead
pass the EAlert to an appropriate EAlertSink and be done with it.
Nothing is final yet. Still hacking on EAlert trying to find an API
that feels right for these use cases.
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.
Given the way the autosave feature was awkwardly bolted on to the
composer, an EExtension seemed like a natural fit. And it helped
clean up some object lifecycle hacks (and bugs).
What we have now is a new module consisting of two EExtensions:
EComposerAutosave extends EMsgComposer and determines when to
kick off an asynchronous autosave operation.
EComposerRegistry extends EShell and offers to restore orphaned
autosave files on startup (which is also asynchronous now).
e-autosave-utils.c holds the actual asynchronous functions and a few
other miscellaneous utility functions.
Source code for the new module lives in /modules/composer-autosave.
Adds a boolean "dragging" property to the EAttachmentView interface,
which becomes TRUE when the user start a drag from the attachment view.
e_attachment_view_drag_motion() and e_attachment_view_drag_drop() both
return FALSE when this property is set.
Also, do not register the entire EMsgComposer window as a drag
destination. Just intercept drag signals from the GtkHTML widget.
Requires gtkhtml commit 344eb5e to fully work correctly.
