... as a preparation for splitting up class AudacityProject.
Use ProjectWindow as an alias for AudacityProject, and fetch it from the
project with a static member function, where certain of its services are used;
pretending they are not the same class.
Use global accessor functions to get wxFrame from the project where only
wxFrame's member functions are needed, so there will be less dependency on
ProjectWindow when it becomes a distinct class.
... 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.
... Unnecessary because transitively included.
But each .cpp file still includes its own .h file near the top to ensure
that it compiles indenendently, even if it is reincluded transitively later.
... and also fixed analogous mistakes in some effects (Vamp, SoundTouch, and
SBSMS effects), found by review of all uses of TrackList::Channels.
The first member of the pair of iterators returned by TrackList::Channels
does not necessarily deference to a null pointer when it is incremented to
the end of the range.
... except Audacity.h
This forces us to make each header contain all forward declarations or nested
headers that it requires, rather than depend on context.
... 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.
... 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
OnTrackSetChanged sets mUpToDate to false, which assumes that
MixerBoard::OnPaint(evt) will be called, but on Linux, the event
appears to be eaten by MixerTrackCluster::OnPaint and TrackClusters
were not updated.
... 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
MixerBoard, LyricsWindow, Screenshot and most effects are now LTR in RTL locales.
Also added a pref so this can be overridden. As RTL affects window creation, the language choice and this preference may only fully take effect after a restart of Audacity.
All backing bitmaps (not just the one in track panel) now are set to 24 bits.
Big thanks to David Bailes for tracking down the root cause of slow BitBlts, and the comments at https://trac.wxwidgets.org/ticket/14403 which led to the fix.
In testing the bitmaps, I also fixed the sizer errors reported for Export.cpp that wxWidgets now reports as ASSERTS when running in debug builds.
... Replace some enum constants with the equivalent values from the more
special-purpose enums, as the wx header files recommend, so overloading
selects the ctors with non-int arguments.
In a full rebuild of the debug project on Mac, this reduces the count of
warnings from 264 to 274.
