... Also removed one line from the track control drop-down, and changed
accelerators to more mnemonic choices.
Also the open page of View Settings... determines track view type after OK
... not per track,
and the preferences or View Settings page has a separate static box for
global settings as opposed to track settings. This is the only global setting
for now.
... SpectrogramSettings does that instead, and Preferences or View Settings
are the user interface for changing it.
Handle invalidation of spectrogram pixel cache for scale type changes,
just as for other changes of settings. No more
TrackArtist::InvalidateSpectrumCache().
View type of track now switches to Spectrum when applying or OKing the
View Settings... dialog and the Spectrogram page is open (and for now
it is still the only page)
It was producing "ghost" windows on OSX in wx3. These were
supposed to be hidden, but they weren't any longer and after
reviewing TipPanel, I realized that there was a separate
code path for OSX entirely...must've gone back to some of the
earliest versions.
Now all platforms use the same bit of code.
... and SelectedRegion, and not ViewInfo or zoom level as a double.
Also some leftOffset arguments.
Assumptions of uniform zoom level persist in TrackArtist::DrawClipSpectrum and
in TrackArtist::DrawClipWaveform but no longer in the rest.
... miscellaneous direct uses of ZoomInfo::zoom to test and set zoom level.
This includes all the remaining assignments to it.
But moving TrackInfo::PositionToTime and TrackInfo::TimeToPosition into
ZoomInfo and using them is needed to eliminate many more uses.
Also #if'd out the unused AudacityProject::OnZoomToggle().
... With a careful sweep of uses of WaveTrack::GetDisplay() to remove
assumptions about the ordering of the values.
Using < and <= on enum values is mostly a bad idea.
... Verified that this works for presses on tool buttons, and keys A, D, F1,
..., F6.
Also fix conditional compilation with EXPERIMENTAL_SCRUBBING_BASIC not defined.
Don't read "/Spectrum/" preferences anywhere but in SpectrumPrefs.cpp.
Don't store global values in TrackArtist.
Possibly some day, there will be other instances of SpectrogramSettings so we
can have independent per-track settings.
