... reduces direct dependencies of ToolManager.cpp.
This frees four files from cycles:
DeviceToolBar
EditToolBar
MeterToolBar
MixerToolBar
Leaving 66 files still in the big s.c.c.
... New files, but (almost) empty; don't use the global variable gAudioIO,
but use one of two accessor function names (which are the same function for
now).
AudioIOBase will have fewer dependencies than AudioIO -- in particular, no
dependency on tracks.
It won't include StartStream. It will contain functions to query the
present state of streams, and device capabilities.
... and break its compile dependency on CommandManager.h by letting it install
callbacks.
This also removes Objective-C mixed code from CommmandManager.
This also eliminates four inclusions of Project.h!
Capture handler state is also global, not per project, though the
CommandManager's callbacks still do depend on the active project.
... 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.
Now cut-preview and looped play revert to using the old fixed speed play-at-speed.
Unfortunately Scrubbing does not (yet) support looped play or cut-preview.
Worth doing for users with wide screens, who want to use the toolbar at full screen width.
Both toolbars can now expand to a little over 2000 pixels width.
Note that the max sizes affect what is drawn. You can make the toolbars wider still, but the sliders inside them won't continue to lengthen.
I moved 'Fit()' from ToolBars into MeterToolBar, because it is a workaround for an incorrect size calculation by MeterToolBar. MeterToolBar is sized as if there is no resizer, so when there is one, the toolbar needs to be expanded (using Fit) to accommodate the resizer.
I also set the min size of MeterToolBar to 150, so that some meter will appear, even if Toolbar shrunk to the minimum.
This adds a new preference to Playback prefs, VariSpeedPlay, on by default, which makes it possible to vary the playback speed slider whilst audio is playing using play at speed. The code uses the Scrubbing playback engine.
This code is not final, but is already useful. Known issues:
1- Playback does not stop and pop-up the Play at Speed button at the end of playing the selection.
2- The scrub widget shows uselessly on the scrub ruler when in Play at Speed mode and the status bar proclaims 'Scrubbing'.
3- At low speeds the playback is clicky, with VariSpeedPlay, even if no changes to speed are being made.
If we can't fix both 1 and 2 by 2.3.0 release time, VariSpeedPlay will be made false by default.
Previously hovering over a down button made no difference.
Also tweaked the appearance of hover-over thumbs on dark theme sliders.
Also tweaked hover images and colours generally.
Classic retains the old style.
Hi Contrast does not distinguish between hover-up and hover-down.
mMidiPlaySpeed doesn't handle all of the options provided by time tracks,
and in fact doesn't even use time tracks. Using the time track
instead allows note tracks to remain synchronized with the rest of the audio.
mMidiPlaySpeed _did_ work where it was used in the transcription tool
bar, but that already updates a time track so no special handling is
needed.
... This makes much code agnostic about how other things (functions and
arguments) are typed.
Many of these neeed to become size_t instead of sampleCount.
