npyscreen - displaying the current time in a FixedText widget?

I'm trying to display the time in a FixedText widget in an NPSAppManaged application.

So far I've got this:

import npyscreen
import datetime
import threading
from time import sleep

class MainForm(npyscreen.Form):
    def create(self):
        self.add(npyscreen.FixedText, value = "Time")

    def afterEditing(self):
        self.parentApp.setNextForm(None)

    def set_value(self):
        return "Tom"

class TestApp(npyscreen.NPSAppManaged):

    def onStart(self):
        self.registerForm("MAIN", MainForm())

        thread_time = threading.Thread(target=self.update_time,args=())
        thread_time.daemon = True
        thread_time.start()

    def update_time(self):
       while True:
           # self.f.wStatus2.value = datetime.datetime.now().ctime()
           # self.f.wStatus2.display()
           sleep(1)

if __name__ == "__main__":
    App = TestApp()
    App.run()

I'm just not sure how to reference the .value parameter for the widget from the thread and update it. What should I be doing?

You need to assign the npyscreen.FixedText to a variable as such:

 def create(self): 
     self.w_time = self.add(npyscreen.FixedText, value = "Time")

Now you can use self.w_time.value to access it.
