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().
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.
It just doesn't belong in Evolution anymore. We don't support syncing
with more modern devices -- see Conduits or SyncEvolution for that -- so
it does not make sense for older model Palm Pilot PDAs to be the lone
exception.
I have repackaged the Evolution-Data-Server conduit modules to be
provided by gnome-pilot itself in bug #619315. This should provide
eqivalent Palm Pilot syncing functionality; it's just being moved to
gnome-pilot.
This completely severs our dependency on deprecated GNOME 2.x libraries
which were still being dragged in by way of gnome-pilot dependencies.
It was also interfereing with our bundling of libgnomecanvas.
For express mode:
- Move the search bar up to the toolbar.
- Hide the "filter" combo box and lock down the first item.
- Hide the "scope" combo box and lock down the first item.
(This is the combo box with "Current Folder" only in the mailer.)
- EShellView owns the search bar widget now instead of EShellContent.
- Insert several nasty hacks that will likely come back to bite me.

Introduce e_extensible_list_extensions(), which provides extensible
objects access to their own extensions, or a subset of them.
Convert EShellBackend to an abstract EExtension subtype. EShell will
load its extensions with e_extensible_load_extensions(), and then obtain
a list of EShellBackend extensions as follows:
shell_backends = e_extensible_list_extensions (
E_EXTENSIBLE (shell), E_TYPE_SHELL_BACKEND);
Because EShellBackend is abstract, its GType is skipped while traversing
the GType hierarchy to find EShell extensions.
The mechanism here is simple but hard to explain without leaning heavily
on object-oriented jargon. Consider this a rough draft. Illustrations
would certainly help clarify.
There's too much ancient, crufty code there that we can't realistically
support anymore. A workaround for those poor users still on 1.x is to
upgrade to some 2.x release first, then upgrade again to 3.x. An error
dialog explaining this will be shown at startup.

Add G_GNUC_NULL_TERMINATED to EAlert functions with variable-length
parameter lists and drop the unnecessary "arg0" parameter so the
function attribute works correctly.
Replace the EVO_EXPRESS environment variable with an --express command
line option. (Note, this adds a new translatable string for --help.)
Add an EUIManager class with an "express-mode" property and custom load
functions that use our new "express" preprocessor. This replaces the UI
manager functions in e-utils.c.
(Also going to see if I can get GTK+ to add an "add_ui_from_string"
method to GtkUIManagerClass that we can override. Then we could just
call gtk_ui_manager_add_ui_from_string() and the preprocessor would
automatically do its thing and chain up.)
Add an "express-mode" read-only GObject property to EShell.
Add e_shell_configure_ui_manager() to e-shell-utils.c. For now this
just creates a one-way property binding:
EShell:express-mode -> EUIManager:express-mode
Call this immediately after e_ui_manager_new(). (EUIManager can't do
this itself because it lives too low in the dependency hierarchy and
doesn't know about EShell.)
The signal uses the name of the newly created shell view as the detail,
so for example "shell-view-created::mail" is emitted when the "mail"
view is created.
Also, add e_shell_window_peek_shell_view() to obtain a shell view if it
exists but without instantiating it.
Using these new tools, teach the templates plugin to wait for the user
to switch to the "mail" view before connecting to its "update-actions"
signal. Previously is was instantiating the "mail" view itself.
EFocusTracker tracks the input focus within a window and helps keep
the sensitivity of "selectable" actions in the main menu up-to-date.
Selectable actions include Cut, Copy, Paste, Select All and Delete.
EFocusTracker has built-in support for widgets that implement the
GtkEditable interface such as GtkEntry and GtkTextView. It also
supports custom widgets that implement the ESelectable interface,
which is a subset of GtkEditable and can apply to anything that
displays selectable content (esp. tree views and ETables).
This commit integrates EFocusTracker with EShellWindow, CompEditor,
EMsgComposer, and ESignatureManager.
It also bumps the GtkHTML requirement to 2.29.5 to utilize the new
GtkhtmlEditor:html constructor property.
Move the search interface to a new widget: EShellSearchbar
The current search rule is now stored in EShellView, and the search
context in EShellViewClass similar to GalViewCollection (since it's
class-specific, not instance-specific).
Also add a couple new signals to EShellView: "clear-search" and
"custom-search" ("custom" refers to an advanced search or a saved
search -- something more complex than a quick search).
Still working out a few kinks. The search entry is clearly trying to
be too many things. We need a different way of indicating that you're
looking at search results. Perhaps a search results banner similar to
Nautilus.
EMailSidebar is a subclass of EMFolderTree that implements the state
saving and restoration feature from EMailShellSidebar. Placing this
in the shared mail library allows Anjal to reuse it.
This tells EShell where to look for EModules. Best practice is to
define the directory in your CPPFLAGS and then pass it to EShell at
instantiation time, like so:
Makefile.am:
evolution_CPPFLAGS = \
-DMODULEDIR=\""$(moduledir)"\"
...
main.c:
shell = g_object_new (
E_TYPE_SHELL, "module-directory", MODULEDIR, ...);
So Anjal can override what it needs to for its own purpose.
Also makes the EShellWindow design a little cleaner.
Methods added:
GtkWidget * (*construct_menubar) (EShellWindow *shell_window);
GtkWidget * (*construct_toolbar) (EShellWindow *shell_window);
GtkWidget * (*construct_sidebar) (EShellWindow *shell_window);
GtkWidget * (*construct_content) (EShellWindow *shell_window);
GtkWidget * (*construct_taskbar) (EShellWindow *shell_window);
EShellView * (*create_shell_view) (EShellWindow *shell_window,
const gchar *view_name);
Also added some new GObject properties to help decouple actions from
internal EShellWindow widgets created by these methods:
EShellWindow:sidebar-visible
EShellWindow:switcher-visible
EShellWindow:taskbar-visible
EShellWindow:toolbar-visible
This -asks- an existing Evolution process to quit. It is equivalent to
selecting File->Quit in the main window. It does not kill the process.
My plan is to use this as part of a new --force-shutdown implementation.
