keyboard

问题 I followed the Apple documentation to move a textfield upwards when the keypad appears.

问题 I want to get the keyboard layout name like "kbdus" for US-English keyboard or "kbdusx" for US-International. I have tried "GetKeyboardLayoutName" from Win32API, but I just got a number (0x20409).
