I pushed a few EShell features up to GtkApplication for GTK+ 3.2,
so we can now trim off the redundancies in EShell.
1) GtkApplication has a new "window-added" signal which replaces
EShell's own "window-created" signal.
2) GtkApplication has a new "window-removed" signal which replaces
EShell's own "window-destroyed" signal.
3) gtk_application_get_windows() now returns a list of windows sorted
by most recently focused, replacing e_shell_get_watched_windows().
4) GtkApplication now provides enough hooks to subclasses that we can
remove e_shell_watch_window() and call gtk_application_add_window()
directly.
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.
An easy way to broadcast application-wide alerts to shell windows.
These alerts will persist in all current and future shell windows
until responded to (either programmatically or by the user).
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.
This module posts an alert to the first EShellWindow when starting
offline, and also posts an alert when the network connection drops.
We get frequent questions on the mailing list from users not realizing
Evolution is starting in offline mode, so this is meant to help address
that confusion.
