Topic: Clear Keyboard buffer
Hi,
I hope I am not off topic asking a wxpython question.
I'm writing a Score counter for Dart games. The software
shows graphical output on a Canvas and accepts keyboard
input (no buttons, no widgest). A stripped version looks
like that:
self.Bind(wx.EVT_CHAR,OnKeyEvent)
.
.
#--
def OnKeyEvent(self, event):
k =event.GetKeyCode()
try:
z=chr(k)
except:
return
if (z in ["0","1","2","3","4","5","6","7","8","9",.."\r"..]:
self.keystr +=z
score=self.CalculateScore(self.keystr)
self.DisplayScore(score)
.
.
if z== "\r" #enter
self.SayScore(score)
self.NextPlayer()
#--
def SayScore(self,number):
if number > 100:
a=os.path.join(self.wavpath,"100.wav")
b=os.path.join(self.wavpath,"%i.wav"%(number-100))
else:
a=os.path.join(self.wavpath,"%i.wav"%(number))
b=""
sound1 = wx.Sound(a)
sound2 = wx.Sound(b)
sound1.Play(wx.SOUND_SYNC)
if b:
sound2.HurryupandPlay(wx.SOUND_SYNC)
#--
The problem is, that during the voice output all keystrokes
are buffered somewhere and are processed when SayScore is
finished. So I have to clear the keyboard buffer at the end
of SayScore. Something like:
evt=MagicFetchPendingKeyEventFunction()
while evt:
evt=MagicFetchPendingKeyEventFunction()
I was thinking about threading (maybe using delayedresults), but
this might be a little oversized for my problem.
Playing the sound ASYNC doesn't work here.
Any ideas?
Thanks in advance
Marcus
