问题 Ok, capturing key codes from special symbols produces different results on keyboards with different layouts. But how about the 'common' characters, like a-z? If you have a QWERTY-keyboard, you'd get key code 81 when you type q . When you have an AZERTY-keyboard, do you get code 81 when you press a , since a is where q 'should' be? Or is the mapping done differently? EDIT: The answer I accepted is probably the best solution when you're capturing keys and want to be sure 'a' is really 'a', but

问题 following pynput documentation I tried this to "cut": 1: select some text in an editor 2: run this_code.py using a shortcut (without leaving the active windows) from pynput.keyboard import Key, Controller keyboard = Controller() with keyboard.pressed(Key.ctrl): keyboard.press('x') keyboard.release('x') The python console open actually print: ^X. The combination of keys are right but it doesn't do what it's suppose to do: cut the selected text store it in the clipboard. (I'm not interested to

问题 I'm building a virtual keyboard in jQuery, using keycode events to tigger an append, but keycode combinations are throwing me for a loop. Here's an example: I want to append a questionmark only when both the SHIFT key (keycode 16) and slash key (keycode 191) are pressed together. I thought the && operator would help, but this only appends the slash: $(document).keydown(function(e) { if (e.keyCode == 16 && e.keyCode == 188 ) { $('#mydiv').append('<span>?</span>'); } }); Any suggestions or idea

问题 I have this logon screen with no textfields at all. When the user scans his id token with rfid scanner, i'll get a 8 character long string. Its the same princip as using an keyboard(just faster). I want my login activity to act, when the user has scanned his token and not before. Is there a smart way implementing this? I can't have any button or textfields, so I have to read keyboard input without listening to a EditText field. So, an empty screen with an image(lock), that listens to an rfid

问题 I tried to call the ToUnicode inside a low level keyboard hook and print the character(s) it returned. However, it seems that the function doesn't take into account whether special keys, such as shift or caps lock were pressed, so the output is the same as from MapVirtualKey function with current key's virtual code passed as parameter. For example ( pressed keys => characters returned by ToUnicode ): abcd => abcd (correct) [caps lock]abcd => abcd (wrong: should be ABCD) ab[holding shift]cd =>
