我在我的代码中多次调用def balloon_tip(title, msg)
。此def显示系统托盘通知气球。我想在任何时候我都称之为def,它应该在单独的进程或线程中处理这个def。我尝试将此def作为线程,但是,它不起作用,因为它包含注册和取消注册WindowsBalloonTip的类。
class WindowsBalloonTip:
def __init__(self, title, msg):
message_map = {
win32con.WM_DESTROY: self.OnDestroy,
}
# Register the Window class.
iconPathName= rootLocation + os.sep + d['iconPathName']
wc = WNDCLASS()
hinst = wc.hInstance = GetModuleHandle(None)
wc.lpszClassName = "PythonTaskbar"
wc.lpfnWndProc = message_map # could also specify a wndproc.
classAtom = RegisterClass(wc)
# Create the Window.
style = win32con.WS_OVERLAPPED | win32con.WS_SYSMENU
self.hwnd = CreateWindow( classAtom, "Taskbar", style, \
0, 0, win32con.CW_USEDEFAULT, win32con.CW_USEDEFAULT, \
0, 0, hinst, None)
UpdateWindow(self.hwnd)
print iconPathName
icon_flags = win32con.LR_LOADFROMFILE | win32con.LR_DEFAULTSIZE
try:
hicon = LoadImage(hinst,iconPathName, win32con.IMAGE_ICON, 16, 16,icon_flags)
except:
hicon = LoadIcon(0, win32con.IDI_APPLICATION)
logging.debug("Image adding fail")
flags = NIF_ICON | NIF_MESSAGE | NIF_TIP
nid = (self.hwnd, 0, flags, win32con.WM_USER+20, hicon, "TITLE")
Shell_NotifyIcon(NIM_ADD, nid)
Shell_NotifyIcon(NIM_MODIFY, \
(self.hwnd, 0, NIF_INFO, win32con.WM_USER+20,\
hicon, "Balloon tooltip",msg,200,title))
# self.show_balloon(title, msg)
global sleep
time.sleep(sleep)
DestroyWindow(self.hwnd)
UnregisterClass(wc.lpszClassName, None)
def OnDestroy(self, hwnd, msg, wparam, lparam):
nid = (self.hwnd, 0)
Shell_NotifyIcon(NIM_DELETE, nid)
PostQuitMessage(0)
# Terminate the app.
def balloon_tip(title, msg):
w=WindowsBalloonTip(title, msg)
答案 0 :(得分:1)
我不是完全确定你在问什么,但如果你只是想在一个线程中运行一个函数,那么这是怎么做的:
import threading
thread = threading.Thread(target=your_function, args=(1, 2, 3)) # args is optional
thread.start()
# thread.join() # if needed
# thread.join(timeout=2.0) # if needed
此外:
f.close()
- 它会自动关闭您不需要在使用反斜杠的地方使用反斜杠,因为括号已经足够了:
some_function_call(arg1, arg, # <-- no `\`; expression wrapped in `()`
arg3, arg4)
您应该从Python 2.x中的object
继承您的类,否则您将获得一个不太好的旧式类:
class WindowsBalloonTip(object):
...
在Python 3.x中,这已经是默认值。
