The only external user of setRecalc() was turning recalculation
on. In fact, this happened when constructing the planner-widget.
However, for example editing of the profile only works when
the recalc flag is on.
This is all very confusing, let's just turn the flag on by
default and remove the accessor. Internally, the planner can
simply use the std::exchange function to set and reset the
recalc flag.
Perhaps the setting/resetting can be replaced by simple
recalc = true;
...
recalc = false;
pairs. It is unclear whether there is need for recursion.
Something to be investigated.

MainTab::updateDiveInfo() is not executed when in the planner.
To decide whether the application is in the planner state,
it queried the profile. Instead, query the DivePlannerPointsModel.
Currently, there is no autoritative carrier of that flag.
However, the MainTab has a dependency on DivePlannerPointsModel
anyway, and therefore this removes a dependency on the
profile. This brings us closer to a state where we can have
multiple profiles.
Ultimately, it is hoped that the whole check can be removed
at this place, making the point moot.

To remove global state, make the dive that DivePlannerModel
works on a member variable. Pass the dive in createSimpleDive()
and loadFromDive(). Moreover, this should pave the way to more
fine-grained undo in the planner. Ultimately, the planner

because of the convoluted way in which the profile and the
planner work on the same dive.

When clicking on "+" in the planner, a default stop point was
added using a signal/slot connection. This used the archaic
string-based connect syntax, because it was realized with
default parameters passed to "addStop()". Instead, add a

Since all other callers do not use callbacks, unslotify
"addStop()". The slot was the only user of the default parameters,

The font-size in printed profiles is based on the size of the profile
in the main window. This makes no sense. Why should changing the
window size change the font-size on printouts?
Matter of fact, when making shrinking the height of the window to
its minimum, comical printouts are obtained (font way too big).
Therefore use an arbitrary rule: Say that profiles 600 pixels high
look reasonable and then scale up to the actual size on the printout.
This may need some tweaking for high-DPI mode. But that seems not

In TemplateLayout, there was a progress indication, which reported
the progress - not of the actual rendering - but of adding the
dives to the "to render" list. Which is of course done in less than
a ms, making the whole thing completely pointless.
Instead, emit progress when actually looping over the dives or
statistics.
Nobody ever noticed the problem because even rendering is done in
fractions of a second and indeed is accounted to only one fifth
of the total progress.
The real purpose of this "fix" is to get rid of the getTotalWork()
function, which was just insane. Instead of asking the TemplateLayout
how many dives it rendered, this number was extracted from
global state. Simply store the number of dives in the TemplateLayout
object instead.
Moreover, fix two coding style issues:
- "Page" variable identifier starting with a capital
- The Printer::render() being defined (as opposed to declared) with
a default parameter. This is not how C++'s default parameters work,

The memory management of the quadrant widgets is a total mess:
When setting the widget, the QSplitters take ownership, which
means that they will delete the widget in their destructor.
This is inherently incompatible with singletons, which must
not be deleted.
To avoid all these troubles, remove the widgets from the
QSplitters in the desctructor of the MainWindow. This of
course means that we now have to take care about deletion
of the widgets.
For local widgets use std::unique_ptr, for singletons use

There was the "application state", which decided what to show
in the "quadrants" and the "view state" which decided which
quadrant to show. These interacted in a hard-to-grasp way.
The "view state" is used to show the map or dive list in
full screen.
I simply couldn't get these two orthogonal states to interact
properly. Moreover the thing was buggy: If a quadrant was hidden,
the user could still show it, by dragging from the side of the
window, at least under KDE.
To solve these woes, merge the two states into a single
application state. If the widget of a quadrant is set to null,
don't show it. So the four "view states" are now "application
states" where three of the four quadrants are not shown.
This also changes the memory management of the widgets:
widgets that are not shown are now removed from the QSplitter
objects. This makes it possible that the same widget is
shown in *different* quadrants.
While writing this, I stumbled upon a Qt bug, which is known
since 2014:
https://forum.qt.io/topic/43176/qsplitter-sizes-return-0
When restoring the quadrant sizes there was a test whether
the quadrant size is 0. If that was the case, a default size
was set. This seems not to work if the widgets were recently
added. Since this test now always fails, make the quadrants
non-collapsible and thus guarantee that 0 is never saved as
a size.

The way the starting time of a new plan was set was bonkers:
1) PlannerWidgets::planDive() invokes DivePlannerPointsModel::
createSimpleDive().
2) createSimpleDive() calls DivePlannerPointsModel::
setupStartTime()
3) setupStartTime() emits a signal startTimeChanged()
4) startTimeChanged is caught by PlannerWidget and sets
the UI field
5) change of the UI field emits a timeChanged() signal which
is connected to DivePlannerPointsModel::setStartTime()
6) setStartTime() sets the time of the plan and displayed_dive
and emits dataChanged()
7) dataChanged() replots the dive()
8) Back in DivePlannerPointsModel::createSimpleDive() the diveplan
start time is overwritten with displayed_dive (the value are
equal owing to 6)
Wow!
But it gets worse:
9) The initial dive plan is set up in createSimpleDive().
Since the profile is drawn in 7) after clearing the displayed_dive
and before constructing the initial plan, the profile is shown
on a dive without samples. It therefore generates a dummy profile.
To make this somewhat less insane, remove the startTimeChanged()
signal in 3), explicitly set the start time of plan and dive to
the one calculated by setupStartTime() and explicitly set the UI
filed in the plannerWidget.
This still indirectly draws the profile via signals in a convoluted
way, but at it straightens out things somewhat. Most importantly,
the profile doesn't have to generate a fake DC.

It turns out that the wrong base class was used for the chart.
QQuickWidget can only be used on desktop, not in a mobile UI.
Therefore, turn this into a QQuickItem and move the container
QQuickWidget into desktop-only code.
Currently, this code is insane: The chart is rendered onto a
QGraphicsScene (as it was before), which is then rendered into
a QImage, which is transformed into a QSGTexture, which is then
projected onto the device. This is performed on every mouse
move event, since these events in general change the position
of the info-box.
The plan is to slowly convert elements such as the info-box into
QQuickItems. Browsing the QtQuick documentation, this will
not be much fun.
Also note that the rendering currently tears, flickers and has
antialiasing artifacts, most likely owing to integer (QImage)
to floating point (QGraphicsScene, QQuickItem) conversion
problems. The data flow is
QGraphicsScene (float) -> QImage (int) -> QQuickItem (float).

The old ways was to select the chart first, then depending on

Willem says that it should work the other way round: select

that.
I'm not arguing one way or the other, just note that the new
way is much more tricky, because it is easy to get unsupported
combinations. For example, there is no chart where the
first variable is unbinned, but the second axis is binned
or has an operation. This makes things distinctly more tricky

Add a new "statistics" application state. In the statistics state
show the statistics widget and the filter in the top quadrants.
The idea is to allow filtering and doing statistics at the same
time.
Sadly, we can't use the filter-widget in different quadrants,
because Qt's ownership model is completely broken / inflexible.
It does not support a widget having different parents and
thus a widget can only belong to one QStackedWidget.
Hiding the map in the statistics view is quite hacky:
Since the view of the quadrants is not determined by the
"ApplicationState", we have to restore the original quadrant
visibility when exiting the stats mode. Therefore, set the
original visibility-state when changing application state.

Qt's memory management scheme is completely broken and messes
with common expectations.
QObjects are organized as a tree. The children are destroyed
in the destructor of QObject. This means that they are destructed
after the destructor of the parent object has run and its
sub-object were destructed. Obviously, this makes no sense as
the child objects should be able to access their parent at
any time.
To restore the commonly expected deterministic order of
construction and destruction, one might simply do away with
Qt's silly object tree and organise things using classical
subobjects. However, that breaks with the Qt-generated UI
classes: The objects generated by these classes are *not*
destructed with the UI class. Instead, they are attached
to the widget's QObject tree. Thus these are again destructed
*after* the widget! Who comes up with such a scheme?
In our case this means that we cannot have models used for
TableViews as subobjects, because the TableView needs the
model to save the column widths in the destructor. Which,
as detailed above is called *after* the desctructor of the
widget! Thus, turn these models into heap-allocated objects
and add them to the QObject tree.
Funilly, this exposes another insanity of Qt's QObject tree:
Children are destructed in order of construction! One would
expect that if objects are constructed in the sequence
A, B, C one can expect that C can, at any time, access B and A.
Not so in Qt: The destruction order is likewise A, B, C!
Thus, take care to init the widgets before the model. Jeez.

TableWidget, so that these kind of subtleties are caught
in the future.

to its content.

Because of subsequent changes there is no clean way to just revert the changes
introduced in commit 8b36cf1051 ("desktop: offer different colors for info tab
titles"), so this manually removes the parts we don't need anymore.
This also restores a tooltip value that was inadvertantly removed in that
commit.

The preference setting seemed far too strange to do this. And not very user
friendly. So instead we figure out if this is a dark theme or not by looking at
text and background colors in the palette, and make sure we get notified if
that changes.

Instead of doing it just for the Information tab, do it for all of the tabs.
There's still room for improvement. But this certainly feels more consistent.

Adding a new virtual function to all of these classes may seem like overkill,
but of course the idea is that likely we'd allow similar changes to all of
them.

Add a preference option to set the color of the text on the information tab to
either MediumBlue, LightBlue or Black. The last two of these colors are meant
to enable areadable font contrast on displays with dark mode.
The choice is saved with the other preferences.
[Dirk Hohndel: this isn't really about dark mode, so changed many of the types
and variable names, changed the user visible texts, and
addressed some whitespace issues]

There was no "title" property on the dive computer table which
was causing an default label of "GroupBox" to appear above the
table. Added a title property to clean up the UI.

Removed the style change to force a style change for the labels on
the dive information page to Medium Blue. This makes labels more
readable in MacOSX dark mode since the default style changes colors
when the mode is shifted from light to dark or vice versa.

Let's simply forward declare the needed structures.
Also removes removes two more unnecessary includes.

Annoyingly, the replacement has only been available since Qt 5.14.
To make the code less messy, implement our own stdToQt conversion helper.

This is slightly different from the previous cleanup around QFlag use as this
one is related to QtWebKit flags. But the logic is the same.
Just syntax to avoid a warning.
