So far the profile operated on the global displayed_dive. Instead,
take the dive to be displayed as a parameter to the plotDive()
functions.
This is necessary if we want to have multiple concurrent
profile objects. Think for example for printing or for mobile
where multiple dive objects are active at the same time.

When moving a planner point with the cursor, nothing

The code took care to not delete planner-points when no
points are selected. However, it assumed that all selected
objects are planner-points. But then it checked whether
the selected object actually is a planner-point. So which
is it?
Remove the outter check for an empty selection. This makes
things more logical and more robust, should there ever
be other objects that can be selected.

Both loadFromDive() callers were clearing the model before
calling loadFromDive(). Move the clearing into that function
since it makes no sense to load into a non-cleared model.
Apparently this changes the way that no-cylinder dives are
treated and the code in ProfileWidget2::repositionDiveHandlers()
must now explicitly check for that condition.

There must not be two dive planner points at the same time
stamp, as this violates the laws of physics (and internal
assumptions).
The corresponding test was done in the profile code at
two different places with floating point arithmetics.
This is a bad idea, because
1) code duplication
2) danger of rounding issues
Instead, do this in one central point in the planner model
and use integer arithmetics. Simply add a few seconds until
a unique timestamp is obtained.

When moving the handle with the mouse, the old code tried
to be smart about changing the active handle when crossing
handles.
To me this always felt weird and it was inconsistent with
mouse-move. Theregore, simply do nothing special at all. The
user should hopefully get an intiutive grasp of what's going

This model is only needed when in plan mode. To enable multiple
profilewidgets at the same time (e.g. for the mobile app or
for printing), make the pointer to DivePlannerPointsModel a
member variable that is initialized at construction time.
Moreover, allow passing null as the DivePlannerPointsModel,
in which case planning will be disabled. This will be useful
for simple printing.

When reordering the points, the DivePlannerPointsModel would
not emit the appropriate move signals, but simply a data-changed
signal over all elements. This obviously violates Qt's
model/view API, though it is probably harmless. Let's do
the right thing so that the frontend knows that the selected
item changed place.
Also, emit dataChanged only on the actually changed element,
not all elements.

The ProfileWidget2 slots, which reacted to model changes were
broken. They did not add / remove items at the changed positions,
but arbitrarily at the end. Moreover, they assumed that only
a single item was added / removed and thus violated the model/view
API.
This worked because the handles are completely reset after each
operation and the model only ever touched single items.
Nevertheless, this has to be fixed if we ever want finer grained
undo.

To remove reliance on global state, pass an "in_planner" argument

This is a bit sad, since the in_planner argument is now passed
to numerous replot() reimplementations of classes derived
from AbstractProfilePolygonItem. However, it is only needed
for one, viz. DiveGasPressureItem. Well, perhaps in the future
more features will depend on the planner mode...

The profile had a static variable which prevented animation

The DiveHandler shows a context menu where a cylinder can be
chosen. This indirectly accesses the global displayed_dive
variable.
Remove this in a step to make the profile reentrant.
The code was quite ominous: instead of simply generating the

with Qt's cumbersome model/view API. All this trampling over

The in_planner() function is incompatible with a reentrant
profile, since it accesses a global variable. In
create_plot_info_new() it is essentially redundant, because
there is a planner_ds (ds = deco_state) parameter that
is used only when in the planner. Therefore use that as
the in_planner indicator: when non-null, the profile is
showing a planned dive.

The code tried to only replot the profile if necessary, notably
when in edit mode or the ceilings are shown.
That seems like pointless premature optimization, which only
complicates things: The profile is replot every time a
"dive handle" is moved, which means that we depend on the
replotting being reasonably fast. Why should it then not
be redrawn if the settings change?
Let's remove this, as it makes control flow easier to reason
about.
This makes the isPlotZoomed member variable redundant. Remove it.

Instead of listening to the dive-data-model changed and
axis changed signals, update the profile items explicitly
once per plot() call. This avoids double replotting of the
dive items.

one after profileYAxis()->setMaximum() and one after
dataModel->emitDataChanged().
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
On each profile replot, the gas axis was implicitly reset
by calling "dataModel->emitDataChanged()", which would send
a signal recieved by the axis. To make the code less confusing
and, more importantly, make order of execution deterministic,
explicitly reset the axis.
Rename the function that resets the axis from "settingsChanged"
to "update" to reflect its usage.
Moreover, remove the "setModel()" function and pass the model
to the constructore. Make it a const reference to make clear
that it can't change during the life time of the axis.

In contrast to most other items, which are cleared in the

This one is extremely obscure: TankItem::setData(), which is
called on every replot, was passed the DivePlotDataModel,
even though it doesn't access that model at all.
Instead, it connect()s to the model to stay informed of changes
to the data. First of all, this should obviously be done
once in the constructor, not on every replot.
But also, the setData() function is called on every replot
one lines before sending the model-changed signal.
Thus, the tankitem was always repainted twice.
Just remove the whole connect() thing and go for a more
deterministic model. Should the tankbar not be repainted
anywhere, add the appropriate calls there.
Accordingly rename the "modelDataChanged" slot to "replot".

settingsChanged() is a virtual function, which is called
when the preferences dialog signals changes. In most derived
classes, the function does nothing.
In two classes, DiveProfileItem and DiveCalculatedTissue, it
replots the item respectively changes its visibility.
However, these two flags are *not* controlled by the preferences
dialog. Indeed, the functions are also connected to finer-grained
qPref signals. Therefore, settingsChanged() can be removed.

Recently (674c20227b), the call to ProfileWidget::clearHandlers()
was moved from PlannerWidgets::replanDive() to ProfileWidget2.
This cause a crash, because the code assumes that the number
of elements in the handles-vector the divepointplanner model
is the same.
Clearing the handles violates this assumption. It turns out
that the clearHandlers() function is broken anyway: it clear
the handles-vector, but not the gases-vector, which should
likewise have the same number of elements. It appears that
the clearHandlers() function is an artifact and it is

On clicking the DivePictureItem "trash" icon, the item would delete
the picture it represents in the currently displayed dive. This needed
an access to the global "displayed_dive" variable, which we want
to get rid of to make the profile more flexible. For example, we
want to render the profile for printing without messing with global
state.
One solution would be to save the dive with every DivePictureItem.
This commit follows a more Qt-ish strategy by handling this via
signals: The close button emits a signal that is recast by the
DivePictureItem and ultimately handled by the ProfileWidget2,
which knows which dive it represents.
