... 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.
... but it does nothing yet.
This will be important to preserve undo/redo behavior of view changes, when
view state is moved out of the proper Track objects.
... in anticipation of making views to tracks many-to-one, but then the rulers
should be one-to-one with the views. So go through the view to get the ruler.
The ruler is really a left-hand extension for each view.
... and use std::enable_shared_from_this
Temporarily putting TrackControls.cpp back into the big s.c.c, now 59 files
Future rewriting might even eliminate all mention of those classes in
the definition of the Track classes.
... Mostly into CommonCommandFlags.cpp, but some elsewhere, to avoid giving
that new file problematic dependencies on LabelTrack, ControlToolBar, and
EffectManager.
Note that CutCopyAvailableFlag is critically ordered, for message purposes,
only with AudioIONotAvailableFlag, the only flag with a message that it combines
with in menu item definitions.
The dependency on LabelTrack.cpp might not be a bad one later, if the track and
its view can be separated, and that would allow CutCopyAvailableFlag to be
put with the others. But much other work on LabelTrack must happen first.
... In fact it was only ever different from flags when flags had the special
NoAutoSelect and mask did not. Now put that bit in the mask too, and make
the special NoAutoSelect always true in MenuManager::GetUpdateFlags(). This
still preserves the intended effects of NoAutoSelect.
