How to Refresh Python Script Once in Awhile?

Question

So I've created a class, which contains GUI using wxPython. How do you make it so that it refreshes itself say every minute?

Answer 1

For things that happen on intervals, use a Timer. From WxPyWiki:

def on_timer(event):
    pass  # do whatever

TIMER_ID = 100  # pick a number
timer = wx.Timer(panel, TIMER_ID)  # message will be sent to the panel
timer.Start(100)  # x100 milliseconds
wx.EVT_TIMER(panel, TIMER_ID, on_timer)  # call the on_timer function

For some reason, this code didn't work when I tried it. The reason was the timer had to be a class member. If you put that code into the init() method and add self. before timer, it should work. If it doesn't, try making on_timer() a class member too. -- PabloAntonio

I've had problems closing my frame, when there was a Timer running.

Here's how I handled it:

def on_close(event):
    timer.Stop()
    frame.Destroy()

wx.EVT_CLOSE(frame, on_close)

Answer 2

I don't work with wxPython, but if there is a method called refresh or something alike, you could start a Thread calling that method every minute.

from threading import Thread
from time import sleep

def refreshApp(app, timespan):
    while app.isRunning:
        app.refresh()
        sleep(timespan)

refresher = Thread(target=worker, args=(myAppInstance, 60))
refresher.start()

EDIT: fixed code so it fits into PEP8

As Niklas suggested I think you're looking for the Refresh() method: http://wxpython.org/docs/api/wx.Window-class.html#Refresh .
