Neither ETree::key-press nor ETableItem::key-press signal definitions
specify a GSignalAccumulator that terminates the signal emission when
a handler returns TRUE, and Evolution 2.29 connects multiple handlers
to ETree::key-press.
When the space key is pressed, the first handler implements the magic
space bar behavior and returns TRUE, which should terminate signal
emission but doesn't because there's no accumulator function on the
signal. So the second handler runs and checks for other keys besides
space. It returns FALSE since it didn't handle the key press.
End result: emission site gets back FALSE (from the second handler) as
the return value, so it thinks the key press was not handled at all and
invokes the fallback handler -- e_selection_model_toggle_single_row() --
which -unselects- the newly selected row, making it appear the next
unread message was never selected.
Several other ETable-related signals that return "handled" flags also
lack GSignalAccumulator functions. I've made a note to myself to fix
those as well.
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.
/apps/evolution/mail/display/show_preview
/apps/evolution/mail/display/thread_list
These keys are no longer needed since we're storing the settings by
folder now in ~/.evolution/mail/config/state. To simplify things we use
hard-coded defaults: TRUE for PreviewVisible, FALSE for GroupByThreads.
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.
After analyzing this again I'm confident we really don't need it.
The only state change is from FALSE to TRUE at startup, and that
one-time event happens while the mail shell backend is starting up
(see: e_shell_backend_start()).
If a need arises to query for this in the future I'll extend the
EShellBackend API with an e_shell_backend_started() function, but
for now there's no need.
EMailBackend is an abstract subclass of EShellBackend that handles
online and offline modes and application shutdown. Placing this in
the shared mail library allows Anjal to reuse it. Evolution's mail
module further extends this class as EMailShellBackend.
Yes, this signal is kind of an ugly monster. I'm not sure how to improve this
significantly. But this commit removes the last EMFolderTreeModel and EShell
dependencies from MailFolderCache, which is a big step towards splitting off
the backend.

Instead of pushing the updates to the right places, the folder cache simply
emits the appropriate signals and other objects are responsible for listening
and handling them appropriately. This allows us to cut down the dependencies of
MailFolderCache significantly, which is a huge step towards allowing us to split
it off for the backend.
Another nice thing about this is that it allows us to trim a lot of 'public' api
from the filter, vfolder, and config classes that were only used by the cache.
Now that stuff can all be internal since they're pulling changes rather than
having the changes pushed.
The last remaining problematic dependency in MailFolderCache is
EmFolderTreeModel. That is next on the chopping block.

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.
Kill ETreeScrolled and convert MessageList to an ETree subclass.
ETreeScrolled is nothing but a GtkScrolledWindow containing an ETree.
It adds nothing of value and actually makes customizing ETree harder.
The changes are mainly including the e-alert-header.h header instead of just
e-alert.h. This allows us to include e-alert.h in non-UI situations when
necessary.
The EError mechanism is used both for error dialogs as well as basic alerts or
user prompts, so we should give it a more general name which matches this use.
This patch also cleans up a few includes of e-alert.h (formerly e-error.h) that
were not actually being used.
