Then the event is: "on a regular basis", i.e. the passage of time.
You can use a wx.Timer to create events at regular intervals, which
your code can respond to:
-------
import wx
class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, "My Window")
panel = wx.Panel(self, -1)
self.text = wx.StaticText(panel, -1, "hello", pos=(40, 40) )
self.timer = wx.Timer(self)
self.Bind(wx.EVT_TIMER, self.on_timer_event)
self.timer.Start(milliseconds=1000, oneShot=False)
def on_timer_event(self, event):
if self.text.GetLabel() == "hello":
self.text.SetLabel("goodbye")
else:
self.text.SetLabel("hello")
app = wx.App(redirect=False)
win = MyFrame()
win.Show()
app.MainLoop()
----------------
Make sure you save the timer in self so that you have a permanent
reference to the object, otherwise the timer will be destroyed when
__init_ returns.
