... Format arguments are substituted into the translation of the msgid, which
may not be known at the time the format arguments are captured (because locale
may change). This allows TranslatableString with arguments to be constructed
at static initialization time.
There is also a special "verbatim" or null context which makes no translations
of msgids.
There is not yet any use of other contexts besides default or null.
Closing sub trees can leave the wrong item selected.
If a node near the bottom of the tree is closed, the node may move
down, and no longer be under the mouse pointer. If further processing
is allowed, then the line at the mouse position is incorrectly selected.
Fix: Don't allow further processing and call SetFocus() ourselves.
My previous fix for this bug, commit 4b437b8, did not work on Mac.
This bug was introduced by my commit b62ed73. This commit was to ensure that when the keyview was the focus, there was always one item selected. This ensures that the focus is indicated visually, and that the Narrator screen reader reads the keyview.
The failed fix, selected an item if necessary when the keyview became the focus.
The current fix reverts b62ed73 and 4b437b8, and ensures that an item is selected each time the items are updated.
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.
