在X中是否可以检测何时在不修改另一个键时按下和释放换档？

Question

如同在标题中一样,除非同时按下另一个键/按钮,否则它似乎不会生成事件.谢谢,詹姆斯

Answer 1

运行xev和按shift给我这个:

KeyPress event, serial 34, synthetic NO, window 0x5a00001,
    root 0xf7, subw 0x0, time 1739516541, (174,173), root:(1021,367),
    state 0x10, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 34, synthetic NO, window 0x5a00001,
    root 0xf7, subw 0x0, time 1739516717, (174,173), root:(1021,367),
    state 0x11, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

是的,这是可能的.
