Hello everybody,
i want to get an event every midgnight. I know wx.Timer, but that uses an intervall where i can’t set the starting time.
I came up with the following idea:
class AlarmClock:
def __init__(self):
print "init timer"
self.t = wx.Timer()
self.t.Bind(wx.EVT_TIMER, self.on_timer)
self.on_timer(None)
def on_timer(self, event):
print "on timer"
if event:
print "it's time"
wx.Bell()
nxt = (
(wx.DateTime_Now().SetHMS(00, 00, 00))
+ wx.DateSpan_Day()
- wx.DateTime_Now()
)
print "next call in", str(nxt)
self.t.Start(nxt.GetMilliseconds(), wx.TIMER_ONE_SHOT)
``
This seems to be working, but i just want to know if someone has a better approach.

The first idea is to make a more frequent timer, let me say, once per minute. Every minute check the system time inside the on_timer function. When it is close enough to the midnight, then do what you need. By the way, what tolerance do you need, when you are going to detect the midnight?
The second idea. You can just schedule you program using cron or another system scheduler.
If your current solution seems to work okay without any performance
issues or other bugs, then maybe you don't need anything else. However,
you could take a look at APScheduler:

If you happen to be on a Linux platform I’d use cron. But all the OS’s have some type of job scheduler. I know this not using wxPython but it works very well (as long as the computer clock works).

Thank you all three for your input.

Why should i make it more frequent? What will be the benefit? I think a tolerance of one minute should be enough.

Interesting but maybe a bit overkill for my simple app.

I knew i should have been more precise 
I have a wxPython app that runs 24/7. I want it every night to do some housekeeping and make a backup of its (internal) data. That’s why i want a wxpython event inside my app.
