Steps to reproduce:
1. Open preferences
2. Select the keyboard category
3. Scroll down the list by any amount
4. Select an item using the mouse. The list scrolls to the top and the wrong item is selected.
The problem occurs because if the list of shortcuts is currently not the focus, then after a left mouse click, KeyView::OnSetFocus() is called, and setting the selection in that function interferes with the mouse selection.
Fix: In KeyView::OnSetFocus(), if there has been a left down event, don't select anything.
Problem:
NumericTextCtrls act on numeric keys, even when modifier keys are pressed.
This shouldn't be the case, and has the knock on effect that shortcuts like ctrl + 1, don't work when a NumericTextCtrl is the focus.
Fix:
Check that there are no modifier keys pressed.
... 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.
... 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.
... Rename it as SetStatus; make it part of AudacityProject not
TrackPanelListener; and use a roundabout event signalling to cause the timer
restart.
Because SetStatus will be one of very few things left in AudacityProject, but
the timer handling will be part of another class decoupled from it.
And TrackPanelListener won't really be needed: TrackPanel will not need to
pretend it doesn't know what an AudacityProject is.
... Just one low-level function for each that simply sets; just one high-level
function for each that also pushes notifications; and to make that work,
toolbars need some rewriting to avoid recursion when the notifications they
post come back to them.
... There was no reason to store the help location preferences as per-project
state. Also move the dialog for quick fixes near its only use in
HelpMenus.cpp.
This takes 22 files out of the big strongly connected component, notably
the much used lower level utilities, ErrorDialog and AudacityException.
HelpSystem itself is still in a small cycle with LinkingHtmlWindow.
... 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.
Problem: this affects NVDA and Narrator, but not Jaws. If a user moves to the Delete button and presses it to delete a label, a label is incorrectly read as the new focus - the focus remains on the Delete button.
GridAx::SetCurrentCell() can be called when the Grid is not the focus, and send a focus event.
Fix: In GridAx::SetCurrentCell() only send an focus event if the Grid is the focus.
Problem. If an item in the list is selected, then if a different view by radio button is selected, Narrator reads the selected item rather than the radio button.
KeyViewAx::SetCurrentLine(int line) can be called when the KeyView is not the focus, and send a focus event.
Fix: In KeyViewAx::SetCurrentLine(int line), only send focus event if the KeyView is the focus.
... 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.
Problem:
If an ASlider in the main window is clicked, then you can't TAB away from the control.
Fix:
Keyboard shortcuts are handled using key down events. However, ASlider was handling char events for reasons unknown. I'm unsure why this was causing a problem, but changing ASlider to handle key down events fixes the bug.
