.. if the user sorts the compare pane contents by clicking
the header the order they are stored is changed too.
NOTE: The table sort is broken since it is alpha not numeric!
This needs to be fixed too.
.. if intervals or date ranges are not checked in the
compare pane then we shouldn't summarise them
.. also fixed up compare pane so first entry ie. what we
are comparing to is always checked.
.. now can drag and drop any date range onto the
home view compare pane to compatre different
seasons, and even across athletes.
.. we setup the metrics and measures in the context
so the charts don't have to, but we still need to
reference the source context for bests and ridefilecache
data
NOTE: We need a mechanism for 'locking' source tabs/athletes
when they are part of a compare to avoid crashing when
a context is deleted whilst we are comparing
NOTE: We till need a way to remove entries from the compare
pane, possibly call it when an athlete is closed too
(see note above).
Now allows you to add intervals and select them and
change colors they will use.
It will maintain the data as a CompareInterval which
also includes a RideFile representation of the interval.
This is stored in Context in a QList as compareIntervals
and can therefore be re-used across all charts.
We now need to think about putting some widgets onto the
Compare 'bar' for turning compare mode on and off and
deleting / reordering / clearing items.
.. this allows us to drag and drop between athletes or
to switch athlete if dropping from outside of GC.
.. also added context to the mime data so the compare pane
will know where the dragged object has come from (ie. it
may be from a different athlete).
We have two new mime data types;
application/x-gc-intervals
application/x-gc-seasons
With packing routines into QMimeData declared
in IntervalTreeView and SeasonTreeView.
To get around an issue with overwrite mode on
drag and drop from the seasons / interval trees
we DO NOT ACCEPT the drop (even though we do
actually process the data).
All we need to do now is unpack the QMimeData in
ComparePane and then add the GUI elements to it etc.
.. compare pane now appears and disappears on both
the analysis view and home view
.. it also is notified of drag/drop events and can
accept the objects dropped
.. it is now time to write the widget for collecting
and managing compare sets
