The EModule, EExtensible and EExtension classes as well as the
e_type_traverse() function have been moved to Evolution-Data-Server's
libebackend library to replace e-data-server-module.c.
Now Evolution-Data-Server modules use the same framework as Evolution.
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.
Split the GTypeModule loader out of EShellModule as EModule, and rename
EShellModule to EShellBackend. Backends (formerly modules) should now
subclass EShellBackend.
This commit converts EShell but breaks all the shell backends.
EActivity objects instead of numeric handler IDs. Create an EActivity,
configure it, and (optionally) connect to its "cancelled" and "completed"
signals. Then hand it to the shell view via e_shell_view_add_activity().
When finished with the activity, call e_activity_finish() and unref it.
