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.
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.
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.
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.
Convert the "startup-wizard" EPlugin to an EExtension, and fix up the
importing UI a bit (but it still needs a lot more love). Importing
progress is now shown directly in the GtkAssistant window.
Define a new EConfigItem type (E_CONFIG_PAGE_PROGRESS) for creating
progress pages in a GtkAssistant.
Also, change EMAccountEditor semantics slightly: you now have to call
e_config_create_window() manually after creating a new EMAccountEditor
instance. This allows extra EConfigItems (specifications for the window
content) to be added manually before the window is created.
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.
This demonstrates how to extend EShell without having to modify and
recompile e-shell.c. If NetworkManager integration is enabled, the
extension is loaded automatically when the EShell is created.
The same pattern can be applied to integrate other network monitoring
software like ConnMan or Microsoft's Wireless Zero Configuration.

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.)
Added em_account_editor_get_widget, and cleaned up the widget listing.
Cleaned the startup wizard code to find it's label by name
Added disabling of power-user 'indentity' frame in the first page express capplet.
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, ...);
Add method pointers to EShellClass for all the EShell signals.
Also rework my previous --quit corner case workaround: we'll want to do
the full shutdown procedure after all, since the backends have already
spun up.
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.
This introduces e-shell-utils for miscellaneous utility functions
that integrate with the shell or shell settings. First function
is e_shell_run_save_dialog(), which automatically remembers the
selected folder in the file chooser dialog.
Also, kill some redundant save dialog functions, as well as some
write-this-string-to-disk functions that block.
