By default Qt will hand off key events to platform-native input methods
on macOS because the OS or additional software can intercept key input
and transform it (e.g. the international variations popping up when
holding down the key for certain letters).
This functionality can lead to certain key combinations being ignored
because they don't call the delegate methods implemented by Qt to
handle the input after it's been interpreted by the Input Method.
Disabling Input Methods for hotkey input fields fixes this issue, as the
native input methods are bypassed entirely and the key events are
handled by the widget and its keyboard events directly.
This changes cleans up some deprecated functions that were removed in
Qt6. Some are placed behind version ifdefs and others are replaced for
their non-deprecated Qt5 version.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
