.. enforce use of QT 5.8 for building the Overview and
use of Qt Charts.
.. Qt 5.7.x doesn't neccessarily come with Qt Charts as it
was a technology preview (and breaks the current Appveyor
builds)
.. hacked in a proof of concept, using Qt Charts
.. only does the time in zone for HR at present, but can now
look to refactor to better code and then add in pace, power
and w'bal time in zone too.
.. note that now we are using Qt Charts the overview will
only be built with Qt >= 5.7
.. although hacked in, at least we get a dashboard that looks
like the real thing (till we have configuration code).
.. need to work on adding time in zones via Qt Charts next !
.. modes for config and view scrapped - too confusing when you
have config of layout vs config of individual cards
.. need to set a constraint on the size of each card to make
it easier to design content and manage typefaces in a
consistent manner across the cards
.. add / delete / modify will be made available at all times.
add will need a '+' card to float at the end of the
dashboard, whilst delete and modify can be on the card
decoration.
.. using a gear icon in the top right to switch between
viewing an overview and configuring it.
.. now need to think about how cards react and are
decorated and the main mechanisms for configuring
the content on the page (not the layout).
.. easing curve for autoscroll should be linear as it can
be continuous and is jarring if speeds up and slows down
.. some of the animation durations were too slow and made the
UI feel slow instead of snappy
.. getting ready to work on card aesthetics
.. reflects changes as they are made and can be
used to scroll the view.
.. we manage this ourselves instead of letting the
view manage it as we also want to diable it.
.. when a scrollbar is disabled it now makes the
slider invisible.
.. use boundaries of view so it doesn't 'suddenly' start
scrolling - you force it by going to the edge or beyond.
.. make sure the mouse is moving in the right direction of
the autoscroll so it stops when you move up/down against
the direction of the autoscroll.
.. you can scroll up and down with up/down arrow keys
and page up/down.
.. the scroll is animated if the distance is far enough
otherwise it just happens immediately.
.. need to add scrollbar scrolling, drag scrolling and
mouse wheel / gesture scrolling next.
