... because we undo the move,
"Demote vertical zooming code into WaveTrack.cpp ..." done at 1f4bf26
That was done so that WaveTrack would not depend on WaveTrackVZoomHandle, but
made it instead depend on ProjectHistory, which is undesirable.
But since then, commit 3797a52 moved the special minimizing code for WaveTrack
into WaveTrackView.
... non-intrusively in the Track suclasses, registering functions instead.
For each abstract factory function (of two), build a table of concrete factory
functions, paralleling the hierarchy of Track subclesses. Dispatch using
runt time type information in the Track objects.
... and LabelTrack listens to its own events, to update certain state.
This is roundabout for now, but that state is view-related and will move into
another class.
... which will simplify later rewrites that associate selection state with
the track group, not the track.
Since LabelTrack isn't notified immediately of selection changes, instead it
always tests whether it is selected, before using the stored selected label
index.
... eliminating some duplication in tables for Wave and Note track controls,
and freeing PlayableTrackButtonHandles from the big s.c.c, though in a cycle
yet with PlayableTrackControls
... and updating of them is accomplished privately in implementation files,
reducing intrusions into TrackPanel and ProjectWindow
This removes #include-s from TrackInfo.cpp, leaving dependency cycles better
than previously
... which I think was only meant to define a precompiled header for speed on
Windows, and is not necessary for compilation. It is not included in many
other places.
The result is to shrink the big s.c.c. from 44 to 38. Five files remain in
a new small component:
CommandManager
Menus
ToolBar
ToolDock
ToolManager
The sixth freed file is AudacityHeaders itself.
... and eliminate some unnecessary calls to SubstitutePendingChangedTrack,
because the track and the substitute store Y and height in their shared
TrackView object.
Also make GetMinimizedHeight() virtual to avoid inclusion of TrackPanel.h in
TrackView.cpp.
... And Track no longer inherits TrackPanelCell, so be careful to rewrite
some dynamic_casts too to check instead for TrackView. Those casts won't fail
to recompile if not rewritten.
