我发现了问题。我几乎可以肯定xtest.fake_input会做一些奇怪的事情，因为当我手动发送按键和- releases时（发现了一些代码），它可以工作
这是一个示例，该示例仅吞下按键时的“ 1”键并将按键释放时的“ x”发送到焦点窗口：
from Xlib.display import Display
import Xlib
from Xlib import X
import Xlib.XK
import sys
import signal
import time
display = None
root = None
def handle_event(event):
print "handle!"
if (event.type == X.KeyRelease):
send_key("x")
# from http://shallowsky.com/software/crikey/pykey-0.1
def send_key(emulated_key):
shift_mask = 0 # or Xlib.X.ShiftMask
window = display.get_input_focus()._data["focus"]
keysym = Xlib.XK.string_to_keysym(emulated_key)
keycode = display.keysym_to_keycode(keysym)
event = Xlib.protocol.event.KeyPress(
time = int(time.time()),
root = root,
window = window,
same_screen = 0, child = Xlib.X.NONE,
root_x = 0, root_y = 0, event_x = 0, event_y = 0,
state = shift_mask,
detail = keycode
)
window.send_event(event, propagate = True)
event = Xlib.protocol.event.KeyRelease(
time = int(time.time()),
root = display.screen().root,
window = window,
same_screen = 0, child = Xlib.X.NONE,
root_x = 0, root_y = 0, event_x = 0, event_y = 0,
state = shift_mask,
detail = keycode
)
window.send_event(event, propagate = True)
def main():
# current display
global display,root
display = Display()
root = display.screen().root
# we tell the X server we want to catch keyPress event
root.change_attributes(event_mask = X.KeyPressMask|X.KeyReleaseMask)
# just grab the "1"-key for Now
root.grab_key(10, 0, True,X.GrabModeSync, X.GrabModeSync)
signal.signal(signal.SIGALRM, lambda a,b:sys.exit(1))
signal.alarm(10)
while 1:
event = display.next_event()
print "event"
handle_event(event)
display.allow_events(X.AsyncKeyboard, X.CurrentTime)
if __name__ == '__main__':
main()
