Description
Many special unprintable keys are not named, causing QKeySequence::toString to fall back to their unicode value, which doesn't make sense to me (i.e. contains weird unicode surrogates) for the following keys:
Key_Alt: b'\xe1\x9f\x80\\udc23' Key_AltGr: b'\xe1\x9f\x84\\udd03' Key_Blue: b'\xe1\x9f\x80\\udd17' Key_Calendar: b'\xe1\x9f\x80\\udce4' Key_ChannelDown: b'\xe1\x9f\x80\\udd19' Key_ChannelUp: b'\xe1\x9f\x80\\udd18' Key_ContrastAdjust: b'\xe1\x9f\x80\\udd0d' Key_Control: b'\xe1\x9f\x80\\udc21' Key_Dead_Abovedot: b'\xe1\x9f\x84\\ude56' Key_Dead_Abovering: b'\xe1\x9f\x84\\ude58' Key_Dead_Acute: b'\xe1\x9f\x84\\ude51' Key_Dead_Belowdot: b'\xe1\x9f\x84\\ude60' Key_Dead_Breve: b'\xe1\x9f\x84\\ude55' Key_Dead_Caron: b'\xe1\x9f\x84\\ude5a' Key_Dead_Cedilla: b'\xe1\x9f\x84\\ude5b' Key_Dead_Circumflex: b'\xe1\x9f\x84\\ude52' Key_Dead_Diaeresis: b'\xe1\x9f\x84\\ude57' Key_Dead_Doubleacute: b'\xe1\x9f\x84\\ude59' Key_Dead_Grave: b'\xe1\x9f\x84\\ude50' Key_Dead_Hook: b'\xe1\x9f\x84\\ude61' Key_Dead_Horn: b'\xe1\x9f\x84\\ude62' Key_Dead_Iota: b'\xe1\x9f\x84\\ude5d' Key_Dead_Macron: b'\xe1\x9f\x84\\ude54' Key_Dead_Ogonek: b'\xe1\x9f\x84\\ude5c' Key_Dead_Semivoiced_Sound: b'\xe1\x9f\x84\\ude5f' Key_Dead_Tilde: b'\xe1\x9f\x84\\ude53' Key_Dead_Voiced_Sound: b'\xe1\x9f\x84\\ude5e' Key_Direction_L: b'\xe1\x9f\x80\\udc59' Key_Direction_R: b'\xe1\x9f\x80\\udc60' Key_Exit: b'\xe1\xa1\x80\\udc0a' Key_Green: b'\xe1\x9f\x80\\udd15' Key_Guide: b'\xe1\x9f\x80\\udd1a' Key_Hyper_L: b'\xe1\x9f\x80\\udc56' Key_Hyper_R: b'\xe1\x9f\x80\\udc57' Key_Info: b'\xe1\x9f\x80\\udd1b' Key_LaunchG: b'\xe1\x9f\x80\\udd0e' Key_LaunchH: b'\xe1\x9f\x80\\udd0f' Key_MediaLast: b'\xe1\x9f\xbf\\udfff' Key_Memo: b'\xe1\x9f\x80\\udcbc' Key_Meta: b'\xe1\x9f\x80\\udc22' Key_MicMute: b'\xe1\x9f\x80\\udd13' Key_Mode_switch: b'\xe1\x9f\x84\\udd7e' Key_Multi_key: b'\xe1\x9f\x84\\udd20' Key_PowerDown: b'\xe1\x9f\x80\\udd0b' Key_Red: b'\xe1\x9f\x80\\udd14' Key_Settings: b'\xe1\x9f\x80\\udd1c' Key_Shift: b'\xe1\x9f\x80\\udc20' Key_SingleCandidate: b'\xe1\x9f\x84\\udd3c' Key_Super_L: b'\xe1\x9f\x80\\udc53' Key_Super_R: b'\xe1\x9f\x80\\udc54' Key_ToDoList: b'\xe1\x9f\x80\\udccc' Key_TouchpadOff: b'\xe1\x9f\x80\\udd12' Key_TouchpadOn: b'\xe1\x9f\x80\\udd11' Key_TouchpadToggle: b'\xe1\x9f\x80\\udd10' Key_Yellow: b'\xe1\x9f\x80\\udd16'
I don't know what a sensible behaviour for the dead keys would be (their 'dead' character? A name?), but I believe all other non-printable keys in the Qt::Key enum should be named correctly.
This is the PyQt-script I used to generate the above list:
from PyQt5.QtCore import Qt from PyQt5.QtGui import QKeySequence keys = {name: value for name, value in vars(Qt).items() if isinstance(value, Qt.Key)} for name, key in sorted(keys.items()): try: string = QKeySequence(key).toString().encode('utf-8') except UnicodeEncodeError: string = QKeySequence(key).toString().encode('utf-8', errors='backslashreplace') print('{}: {}'.format(name, string))
