The problem is not that the first timer ist stopped, the problem is
that both timers happen to call the same method in the end.
Think of the "Bind" method as an assignment: it assigns a handler
function to an event source. If you call it twice for the same event
source, the second call will overwrite the first event handler. That's
what happens in your code.
The easiest way to change this is by using different ids for the
timers:
def startTimer1(self):
self.t1 = wx.Timer(self, id=1)
self.t1.Start(2000)
self.Bind(wx.EVT_TIMER, self.OnUpTime, id=1)
def startTimer2(self):
self.t2 = wx.Timer(self, id=2)
self.t2.Start(1000)
self.Bind(wx.EVT_TIMER, self.OnTime, id=2)
This way, the timers launch two different events, which are bound to
two different methods.
