Problem:
Currently calling Track::EnsureVisible() also sets the track as focus.
In Audacity 2.3.3 the timing of the code to set the focus was changed. Rather than a direct call, an event is queued, and then the focus is set. This has changed the timing of the focus event which is sent with respect to other focus and name change events. In particular in the case of toggling the selectness of the focused track, this moved the focus event to be after the name change event.
These changes only had an effect on NVDA - Jaws and Narrator were unaffected.
The introduction of this bug has highlighted an existing problem.
1. There are a small number of existing cases where a track needs to be visible, but where it is already the focus, and so setting the focus is unnecessary. For example, pressing Enter to toggle whether a track is selected.
2. Some of the Audacity code which calls EnsureVisible() is written with the assumption that EnsureVisible() doesn't set the focus, and so there are unnecessary focus events. Whilst other code which calls EnsureVisible() assumes that it also sets the focus. Confusion.
The Fix:
Remove the setting of focus from within Track::EnsureVisible(), and so remove the unnecessary focus events.
Calls to set the focus were added before calls to EnsureVisible where the code was relying on EnsureVisible to set the focus. In TrackPanel::ProcessUIHandleResult, and TrackPanel::OnMouseEvent, I wasn't sure if the focus needed to be set, so called it anyway to ensure that the behaviour did not change.
So I would like to remove the setting of focus from within Track::EnsureVisible(), and add explicit calls to set the focus where necessary.
I think this would make the code clearer, remove unnecessary calls to set the focus, and make it easier to keep NVDA happy.
... Let the window respond to an undo manager event instead, whenever there
is a push or modify
Maybe this makes a few unnecessary redraws that did not happen before. If
that is important, then we should figure out how to put the logic for eliding
the redraw into ProjectWindow, and the extra information needed for the
decision into the events, but not make intrusions in other code all over the
place.
... 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.
... 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.
... that is, a factory function, open, close, import, undo/redo/rollback.
Also the callbacks from AudioIO, which need to invoke undo history push when
recording stops.
It is meant as a high-level class using several of the other things attached
to the project, while AudacityProject will be a low level class acting mostly
as just the container of the attached structures.
... 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.
Following a lengthen discussion on the quality list, consensus is this option
should always have been off by default. The main argument for not changing
it now was that 'on' is what users have come to expect.
... so that we can use Track::SharedPointer without undefined behavior even on
tracks that don't yet belong to any TrackList.
Also fix the return type of function template TrackList::Add and remove some
casts.
