【问题描述】:
我正在尝试结合使用自动光标定位和 pyWinhook 在多屏桌面设置上实现光标环绕。最终,当我点击屏幕的最右侧或最左侧边缘时,我希望将代码的功能扩展到不同的系统,但是现在我通过尝试使其在单个上起作用而省略了网络位系统。
最初我将这个简单的脚本放在一起,使用 pyautogui 进行包装:
import pyautogui
MAX_X, MAX_Y = pyautogui.size()
MAX_X -= 1
MAX_Y -= 1
def detect_wrap():
x, y = pyautogui.position()
if x >= MAX_X:
pyautogui.moveTo(0,y)
elif x <= 0:
pyautogui.moveTo(MAX_X,y)
elif y >= MAX_Y:
pyautogui.moveTo(x, 0)
elif y <= 0:
pyautogui.moveTo(x, MAX_Y)
return
print(pyautogui.size())
while True:
detect_wrap()
这很好用,但最后会出现烦人的无限循环,所以我尝试寻找一种更干净的方法来处理它,偶然发现了 pyWinhook 和 pythoncom 并编写了一个类似的脚本来尝试实现相同的目标。但是,当我这样做时,不是从最底部跳到顶部,从最右边跳到左边等等。脚本卡在边缘并停留在那里。虽然我不确定为什么。我放入了一些打印语句以试图揭示一些信息,并看到鼠标确实移动到了对面的边界,但有些东西一直让它回到原点。我深入研究 pyautogui 并弄清楚它是如何移动光标的(使用 ctypes.windll.user32.SetCursorPos(xpos, ypos)),所以我将 pyautogui 排除在外。我剩下的看起来像这样(请注意,这是一项正在进行的工作):
import win32api
import pyWinhook as pyHook
import pythoncom
import ctypes
import win32api, win32con
import win32.win32gui as win32gui
import os, sys, time
SCREEN_WIDTH = 0 # This will actually be set later, when we know the size of the attached screen(s)
SCREEN_HEIGHT = 0 # This will actually be set later, when we know the size of the attached screen(s)
XMAX = 0 # This will actually be set later, when we know the size of the attached screen(s)
YMAX = 0 # This will actually be set later, when we know the size of the attached screen(s)
XMIN = 1
YMIN = 1
def setWrapPos(xpos, ypos, border):
win32gui.ReleaseCapture()
if border == 'left':
xpos = SCREEN_WIDTH - 1
elif border == 'top':
ypos = SCREEN_HEIGHT - 1
elif border == 'right':
xpos = XMIN
elif border == 'bottom':
ypos = YMIN
else:
print('ERROR: Illegal border passed to setWrapPos()')
ctypes.windll.user32.SetCursorPos(xpos, ypos)
time.sleep(0.01)
return
def onclick(event):
print('Detected mouseclick at (%d,%d)' % event.Position)
return True
def trackMouse(event):
hm.UnhookMouse()
flags, hcursor, coords = win32gui.GetCursorInfo()
xpos, ypos = coords
print("Mouse at (%d, %d)" % (xpos, ypos))
if (xpos <= XMIN):
setWrapPos(xpos, ypos, 'left')
elif (ypos <= YMIN):
setWrapPos(xpos, ypos, 'top')
elif (xpos >= XMAX):
setWrapPos(xpos, ypos, 'right')
elif (ypos >= YMAX):
setWrapPos(xpos, ypos, 'bottom')
flags, hcursor, coords = win32gui.GetCursorInfo()
xpos, ypos = coords
print("Mouse moved to (%d, %d)" % (xpos, ypos))
hm.HookMouse()
return True
def onWinCombo(event):
if event.Key == 'X':
print('Lcontrol-X was detected. Exiting.')
hm.UnhookMouse()
hm.UnhookKeyboard()
os._exit(0)
else:
hm.KeyDown = onKeyboardEvent
return False
def noMoreCombo(event):
hm.KeyDown = onKeyboardEvent
hm.KeyUp = None
return False
def onKeyboardEvent(event):
print('Keyboard action detected, ' + str(event.Key) + ' was pressed.')
if str(event.Key) == 'Lcontrol':
print('Lcontrol detected.')
hm.KeyDown = onWinCombo
hm.KeyUp = noMoreCombo
return True
curr_right = 0
mons = win32api.EnumDisplayMonitors()
i = 0
while i < win32api.GetSystemMetrics(win32con.SM_CMONITORS):
minfo = win32api.GetMonitorInfo(mons[i][0])
if minfo['Monitor'][2] > SCREEN_HEIGHT:
SCREEN_HEIGHT = minfo['Monitor'][3]
print("Monitor #" + str(i+1) + ": " + str(minfo['Monitor'][2] - curr_right) + "x" + str(minfo['Monitor'][3]))
i += 1
curr_right += minfo['Monitor'][2]
minfo = win32api.GetMonitorInfo(mons[i-1][0])
SCREEN_WIDTH = minfo['Monitor'][2]
XMAX = SCREEN_WIDTH - 1
YMAX = SCREEN_HEIGHT - 1
hm = pyHook.HookManager()
hm.SubscribeMouseAllButtonsDown(onclick)
hm.SubscribeMouseMove(trackMouse)
hm.KeyDown = onKeyboardEvent
hm.HookMouse()
hm.HookKeyboard()
pythoncom.PumpMessages()
代码有效,但无论我尝试了什么,我似乎都无法避免光标弹回边框而不是跳到另一边。我的想法已经用完了,所以想也许这里有人会想到发生了什么。
提前感谢您的任何见解。
