Recording goes through ffmpeg's avfoundation input, and opening a capture
session there brings the process that did it to the front. ffmpeg is a
child of Dikte with no bundle of its own, so macOS credits the move to
Dikte: the window the user was dictating into goes inactive, its caret
stops, its title bar greys out, and the Cmd+V at the end of the run lands
somewhere other than the document it was meant for. Measured with a
TextEdit document in front:
press the shortcut front = TextEdit
recorder.start returns front = TextEdit
89 ms later front = Dikte
Nothing about the capture session can be asked not to do this. Starting
ffmpeg in its own session, and clearing __CFBundleIdentifier from its
environment, were both tried and both measured to make no difference, so
it is undone instead: the application in front is noted before the
indicator goes up, and a short watch puts it back the moment Dikte takes
the front. Measured at 99 ms from the moment it is taken, against the
title bar staying grey for the whole dictation before. All three ways in
do it, dictation, agent and meeting, since all three open the same
capture.
The indicator had a share of the same problem and needed AppKit for it
too, so mac_window.py carries both. An NSPanel is hidden by the system
the moment its application stops being the active one, which for a
dictation indicator is immediately, and ordering one to the front brings
its application with it unless it carries the nonactivating style bit.
Neither is reachable through Qt.
The runtime is loaded in _appkit() rather than at import, the way paste.py
loads its frameworks in _macos_api(), so the module imports on a machine
with no AppKit and the tests below run there as well: 52 new tests, none
of them skipped anywhere.
