Question

我对python Tkinter相当新。我做了一些谷歌搜索，但无法找到一个好的答案。

我有一个Tkinter GUI，如果通过串口检测到某些命令，它会执行某些功能。我有一个脚本，就像一个名为listener.py的串口侦听器。我希望这个listener.py与我的tkinter程序通信并执行一个函数。例如，从下面的代码中，我希望我的listener.py执行self.Start_Test_Button。怎么可以这样做？

下面是我的listener.py代码：

def ReadFromPort(port) :

  if os.path.exists(port) :

    ser = serial.Serial(
    port=port,\
    baudrate=9600,\
    parity=serial.PARITY_NONE,\
    stopbits=serial.STOPBITS_ONE,\
    bytesize=serial.EIGHTBITS,\
        timeout=0)

    #this will store the list
    seq = []
    count = 1
    while True:
    time.sleep(1)

    for c in ser.read():
        seq.append(c)
        joined_seq = ''.join(str(v) for v in seq) #Make a string from array

        if c == '\n':
        received = joined_seq.strip("\n")
        received = received.strip('\r')
        received = received.strip()
        #print received
        if "Test" in received :
          #print "got it"
          #print received
          ser.close()
          return "GO"
          sys.exit()

    else :
      return "Port Not Found"

- 以下是我的Tkinter代码： -

    #!/usr/bin/python

    import "whatever needed"

    class myThread (threading.Thread):
         def __init__(self, name, ser):
            threading.Thread.__init__(self)
            self.name = name
            self.ser = ser
            self.buf = ""

    class PT_Inline(Tkinter.Tk):
        def __init__(self,parent):
            Tkinter.Tk.__init__(self,parent)
            self.parent = parent
            self.initialize()

        def initialize(self):
            self.geometry("600x400")

            self.resizable(1,1)
            self.title("Some Title")
            self.configure(background = 'white')

            #self.attributes('-alpha', 0.5)

        Function_Button1 = Tkinter.Button(self, text = "Start Test", fg = "black", bg = 'whitesmoke',  width = 15, height = 2, font = "ArialBlack 7 bold roman", command = self.Start_Test_Button)
        Function_Button1.place(relx = .6, rely = .8, anchor = "c")
        Function_Button1.config(highlightbackground = "black")
        Function_Button1.config(highlightthickness = 1)
        #Function_Button1.config(state=DISABLED)

    def Start_Test_Button_funcs(self) :
        self.labelVariable_status.set("Waiting For Command")

        port = "/dev/ttyACM1"

        Read = ReadFromPort(port)
        print Read
        if Read == "PortNotFound" :
          self.serial_number = "N/A"
          fail_message = Read
          self.Raise_ERROR(self.serial_number, fail_message)

        elif Read == "GO" :
          "Do ALL Functions Here"

    def Start_Test_Button(self) :
        t = threading.Thread(target = self.Start_Test_Button_funcs)
        t.start()

    if __name__ == "__main__":      
        app = PT_Inline(None)
        app.title('Title')
        subprocess.Popen(app.mainloop())

python从不同的python脚本调用Tkinter函数
