我def balloon_tip(title, msg)
在我的代码中多次调用。这个 def 显示系统托盘通知气球。我希望任何时候我调用这个 def,它都应该在单独的进程或线程中处理这个 def。我尝试将此def设置为线程,但是它不起作用,因为它包含注册和注销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))
