GTK's logic might be a bit flawed (or complicated) in terms of
"focus-out-event" and GtkComboBoxEntry objects as it does not work
by attaching said signal type directly to the GtkComboBoxEntry.
Perhaps it only makes sense for text input.
Since "focus-out-event" works for GtkEntry, we can retrieve the child
GtkEntry from the combo using gtk_bin_get_child(GTK_BIN(combo)
and attach the event handler to that.
This change should make it possible to update gas_model (GtkListStore)
when changing the widget focus with both the keyboard and mouse clicks.

Once again Gtk does everything it can to make our lives miserable. It

Linus' treeview for the plan input is just too ugly for words. And doesn't
work, either.
So let's go with plan C: a table of waypoint entries. Depth, duration (or
absolute time), and gas used. The gas is a combobox that does completion.
I am reusing Linus' validation functions / parsers.
This works if you can fit your dive into the four waypoints that are there
by default. The add waypoint button is hooked up but even though it does
what I think should modify the dialog that is currently displayed that
clearly doesn't work.
But at least it "mostly" works and isn't as horrifyingly uggly as the
first two attempts.

Yes, you can actually enter your segments now.
No, it's not wonderfully user-friendly. If you don't enter enough
segments to create a dive plan, it will just silently fail, for example.
And the <tab> key that should get you to the next editable segment
doesn't. And so on. But it kind of works.

This comes with absolutely no gui - so the plan literally needs to be
compiled into Subsurface. Not exactly a feature, but this allowed me to
focus on the planning part instead of spending time on tedious UI work.
A new menu "Planner" with entry "Test Planner" calls into the hard-coded
function in planner.c. There a simple dive plan can be constructed with
calls to plan_add_segment(&diveplan, duration, depth at the end, fO2, pO2)
Calling plan(&diveplan) does the deco calculations and creates deco stops
that keep us below the ceiling (with the GFlow/high values currently
configured). The stop levels used are defined at the top of planner.c in
the stoplevels array - there is no need to do the traditional multiples of
3m or anything like that.
The dive including the ascents and deco stops all the way to the surface
is completed and then added as simulated dive to the end of the divelist
(I guess we could automatically select it later) and can be viewed.
This is crude but shows the direction we can go with this. Envision a nice
UI that allows you to simply enter the segments and pick the desired
stops.
What is missing is the ability to give the algorithm additional gases that
it can use during the deco phase - right now it simply keeps using the
last gas used in the diveplan.
All that said, there are clear bugs here - and sadly they seem to be in
the deco calculations, as with the example given the ceiling that is
calculated makes no sense. When displayed in smooth mode it has very
strange jumps up and down that I wouldn't expect. For example with GF
35/75 (the default) the deco ceiling when looking at the simulated dive
jumps from 16m back up to 13m around 14:10 into the dive. That seems very
odd.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
The old implementation was broken in several ways.
For one thing the GF values are percentages, so they should normally be
0 < GF < 1 (well, some crazy people like to go above that).
With this most of the Bühlmann config constants were wrong.
Furthermore, after we adjust the pressure tolerance based on the gradient
factors, we need to convert this back into a depth (instead of passing
back the unmodified depth - oops).
Finally, this commit adds closed circuit support to the deco calculations.
Major progress and much more useful at this stage.

This seems like a strange way to capture the FOCUS_CHANGE event, but
manually trying to register a callback for it fails. Yet registering a
callback for every event and then filtering for FOCUS_CHANGE in the
callback works. Go figure.
But with this commit you can actually change the GF settings in the
preferences dialog and once you tab out of the entry field the change gets
immediately applied - nice to play with the effects of changing GF values.

There were some minor problems when moving the selection
cursor around:
1) If the selection was larger than 1, it was possible
for the selection to get "stuck" in the middle of the list.
This patch approaches this by always calling
gtk_tree_selection_unselect_all() before
gtk_tree_selection_select_iter(), or simply always making
sure we have one selected iterator when navigating with the keys.
2) When there was a single top level dive before the first trip
it wasn't possible to navigate trough the child dives of said
trip in both directions.
The patch attempts to fix this by having the hunks/checks:
if (idx < 0) {
(idx is of a trip) performed regardless of other conditions.
*** Note: testing was done by importing all test*.xml
dives with auto-group on.
[Dirk Hohndel: adjusted the patch to also fix on_key_press to only grab
the key if no modifier key is pressed; otherwise this
breaks shift-cursor-keys for selecting multiple dives.]

Having two spots to toggle autogroup had always been a clear sign of
insanity. The inconsistent ludicrous semantic of when we remembered the
state of autogroup was even worse.
This finally gets rid of that disaster and drops the autogroup setting
from the preferences and makes it instead a per file property. When you
save a file, it saves the state of the autogroup toggle. This seems much
more useful - you may have files where you want to create trips by
default. And others, where you don't.

This commit steals the cursor up and down keys away from gtk so regardless
where gtk thinks the focus may be, we can still use the keys to change
between dives.
In the current UI design where all editing happens in separate windows
this works as expected, as we only grab the keys for the main window. If
we manage to re-enable in-place editing then we need to make sure that
this doesn't cause problems (as gtk uses up/down for the ability to change
drop down selections in combo boxes or values in spin buttons. So we must
make sure that we stop stealing these keys once we start editing something
(in which case simply switching to the next/prev dive wouldn't be a good
thing, anyway).

Those only come from a number of development versions of Subsurface that
didn't include the deviceid in the divecomputer entry. There is no way of
telling different dive computers (of the same model) apart, so assigning a
nickname to such an entry then creates incorrect output when loading an
XML file from someone else (e.g. Linus and I both have a Uemis SDA and
both may have entries for our own SDA with deviceid 0; then the nickname
Subsurface shows for any Uemis SDA entry with a deviceid of 0 depends on
whether I last loaded his XML file or mine; that makes no sense).
This should only affect the develoers who stored XML files with one of the
development version of Subsurface that didn't store deviceids.

This adds the capability to actually view all your dive computers, by
adding a menu item under "Log"->"View"->"Next DC" to show the next dive
computer.
Realistically, if you actually commonly use this, you'd use the
accelerator shortcut. Which right now is Ctrl-C ("C for Computer"),
which is probably a horrible choice.
I really would want to have nice "next/prev dive" accelerators too,
because the cursor keys don't work very well with the gtk focus issues.
Being able to switch between dives would also make the "just the dive
profile, maam" view (ctrl-2) much more useful.
The prev/next dive in the profile view should probably be done with a
keyboard action callback, which also avoids some of the limitations of
accelerators (ie you can make any key do the action). Some gtk person,
please?
Anyway, this commit only does the dive computer choice thing, and only
