复制代码

2 功能描述

模拟键盘的输入；
源码如下：

class Keys(object):    """    Set of special keys codes.    """
    NULL = '\ue000'    CANCEL = '\ue001'  # ^break    HELP = '\ue002'    BACKSPACE = '\ue003'    BACK_SPACE = BACKSPACE    TAB = '\ue004'    CLEAR = '\ue005'    RETURN = '\ue006'    ENTER = '\ue007'    SHIFT = '\ue008'    LEFT_SHIFT = SHIFT    CONTROL = '\ue009'    LEFT_CONTROL = CONTROL    ALT = '\ue00a'    LEFT_ALT = ALT    PAUSE = '\ue00b'    ESCAPE = '\ue00c'    SPACE = '\ue00d'    PAGE_UP = '\ue00e'    PAGE_DOWN = '\ue00f'    END = '\ue010'    HOME = '\ue011'    LEFT = '\ue012'    ARROW_LEFT = LEFT    UP = '\ue013'    ARROW_UP = UP    RIGHT = '\ue014'    ARROW_RIGHT = RIGHT    DOWN = '\ue015'    ARROW_DOWN = DOWN    INSERT = '\ue016'    DELETE = '\ue017'    SEMICOLON = '\ue018'    EQUALS = '\ue019'
    NUMPAD0 = '\ue01a'  # number pad keys    NUMPAD1 = '\ue01b'    NUMPAD2 = '\ue01c'    NUMPAD3 = '\ue01d'    NUMPAD4 = '\ue01e'    NUMPAD5 = '\ue01f'    NUMPAD6 = '\ue020'    NUMPAD7 = '\ue021'    NUMPAD8 = '\ue022'    NUMPAD9 = '\ue023'    MULTIPLY = '\ue024'    ADD = '\ue025'    SEPARATOR = '\ue026'    SUBTRACT = '\ue027'    DECIMAL = '\ue028'    DIVIDE = '\ue029'
    F1 = '\ue031'  # function  keys    F2 = '\ue032'    F3 = '\ue033'    F4 = '\ue034'    F5 = '\ue035'    F6 = '\ue036'    F7 = '\ue037'    F8 = '\ue038'    F9 = '\ue039'    F10 = '\ue03a'    F11 = '\ue03b'    F12 = '\ue03c'
    META = '\ue03d'    COMMAND = '\ue03d'
