... Reimplement the ESC key handling in TrackPanel and time ruler on all
operating systems so that it does not rely on the focused window, but instead
uses the application-wide event filter.
This includes reversion of 9491605cfc
... except Audacity.h; and in no others.
Do so even if Experimental.h gets multiply included, as in both the .h and
.cpp files.
This makes it easier to do a text scan to be sure there are no unintended quiet
changes of meaning because of omission of Experimental.h when the flag is
an enabled one.
Also move inclusions of Experimental.h earlier.
Also don't require Experimental.h to be preceded by Audacity.h to define
EXPERIMENTAL_MIDI_OUT correctly.
... instead, re-process the event, and let each handler bind to the one it
depends on.
This still leaves a critical ordering of construction of playback scroller and
play indicator overlay in AudacityProject::AudacityProject (reverse of the
previous), but that will be removed by other means.
... for wxString and wxArrayStringEx, holding file paths (absolute or relative,
directory or plain file); to be replaced later with different types
(not yet using std::vector, becase of some uses of wxArrayString::Index with
two arguments)
... which will make it easier to change the types of those containers to
std::vectors of other string-like classes
for wxString,
IsEmpty => empty
Clear => clear
Alloc => reserve
for wxArrayString,
Count => size
GetCount => size
IsEmpty => empty
Add => push_back
Clear => clear
Empty => clear
Sort => std::sort (only with default comparator)
SetCount => resize
Last => back
Item => operator []
Alloc => reserve
... in case clip boundaries don't match and the right channel covers a greater
time extent than the left.
Don't lose those parts of the right channel, before or after, and also make the
start time of the project correct in case the right channel starts earlier.
This is an old bug, going back as far as the git history.
... Which is also sufficient to detect undo/redo/rollback
And detects more often than undo state changes, so that if you drag a track
in TrackPanel, the same permutation is seen at once in MixerBoard, even before
button-up
