This is related to bug 698275, which did not cover all cases.
The problem here is that the dconf can in certain situation claim
that everything changed (path "/" changed), which GSettingsBinding
propagates to a GObject property unconditionally and GObject's
property setter (g_object_set_property()) also notifies about
the property change unconditionally, despite the real descendant
property setter properly checks for the value change. After all
these false notifications a callback on "notify" signal is called
and possibly an expensive operation is run.
Checking whether the value really changed helps in performance, for
which were added new e-util functions:
e_signal_connect_notify()
e_signal_connect_notify_after()
e_signal_connect_notify_swapped()
e_signal_connect_notify_object()
which have the same prototype as their GLib counterparts, but they allow
only "notify::..." signals and they test whether the value really changed
before they call the registered callback.
This removes all traces of Express Mode from all but the contact editor
and calendar appointment editor. Need to evaluate the remaining cases
individually.
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.
With lockdown settings available through GSettings, widgets can handle
lockdown integration themselves without having to use EShellSettings.
Also fixed a few places where printing or save-to-disk actions were
either not properly wired up or not responding to lockdown settings,
but much more work needs done. Attachments, for example, are not
honoring the disable-save-to-disk setting at all.
This too requires the recently-added gsettings-desktop-schemas
dependency.
You can now amend the predefined actions in an EAlert by calling
e_alert_add_action(). Useful for adding actions from an existing
GtkUIManager.
Call e_alert_peek_actions() to obtain a combined list of predefined
and custom actions. These will typically serve as "related" actions
for GtkButtons (cf. gtk_activatable_set_related_action()).
Also, both EShellWindow and EShellView now implement EAlertSink. Use
EShellWindow for application-wide alerts, EShellView for view-specific
alerts.
Note that express2 got some documentation for EExtensible and friends,
and that documentation is not in gnome-2-30 yet. We need to cherry-pick
those commits into gnome-2-30 and elsewhere.
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.

We can't require the use of EUIManager everywhere because we don't
control all the UI manager instances -- the most compelling example
being the composer, whose UI manager comes from GtkhtmlEditor.
Instead, EPluginUI will check the instance type and pick an appropriate
"load_from_string" function.
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.)
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.
