self.root.geometry('{}x{}+{}+{}'.format(self.w, self.h, x, y))

def packBtn(self):

self.btnSer.pack(padx=20, side='left')

btnQuit.pack(padx=20, side='right')

def event(self):

if self.stat:

self.stat = False
self.root.iconbitmap(self.stoIco)
else:
if self.staFunc():
self.btnSer['text'] = '停止服务'
self.stat = True
self.root.iconbitmap(self.staIco)

def loop(self):
