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.
EActivity now uses a GCancellable to manage cancellations, instead of
having its own redundant cancellation API. API changes are as follows:
+ e_activity_get_cancellable()
+ e_activity_set_cancellable()
- e_activity_cancel()
- e_activity_is_cancelled()
- e_activity_get_allow_cancel()
- e_activity_set_allow_cancel()
EActivity's "cancelled" signal remains, but only as a repeater for
GCancellable::cancelled signals. It should not be emitted directly.
The presence of a GCancellable implies that cancellation is allowed.
EActivity does not create its own default GCancellable, it has to be
given one.
If a CamelOperation (cast as a GCancellable) is given, EActivity will
configure itself to listen for status updates from the CamelOperation
and propagate the information to its own "primary-text" and "percent"
properties.
These changes allowed me to start cleaning up some of the incredibly
convoluted logic in mail-mt.c -- in particular, mail_operation_status()
is completely gone now. mail-mt.c is still in a transitional state --
much more significant changes coming soon.
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.
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.
EAttachmentHandler predates EExtension, so this is really just a code
cleanup to use the extension framework. But this also demonstrates that
extensions can target interfaces as well as instantiable types, since
EAttachmentView is an interface.
What's also nice is EAttachmentView no longer has to directly interact
with attachment handlers. Instead of EAttachmentView having to query
each attachment handler for drag-and-drop info, each handler now pushes
its own drag-and-drop info to its EAttachmentView during initialization.
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.
e_preferences_window to take factory callbacks and store a reference
to the shell. - This makes start-up substantially faster, particularly
on Atom (eg.).
Remove a number of idle handlers used to create these UIs in the
first instance, cleaning the code.
The new height-for-width logic in GTK3 doesn't like my trick to center a
GtkExpander's label widget, so I have to disable it entirely for GTK3 or
else Evolution crashes when opening a composer window.
Bug #614049 has a GtkExpander patch that would let me do it properly.
