Hi, wxPython is cool and easy to use, But I ran into a problem
recently when I try to write a GUI.
The thing is I want to periodically update the content of StatixText
object, so after create them, I pack them into a list...the problem
comes when I later try to extract them from the list! I don't know
why?
my code is as following:
import wx, socket
import thread
class MyFrame(wx.Frame):
firstrun = 0
def __init__(self):
wx.Frame.__init__(self, None, -1, 'Notifier')
self.panel = wx.Panel(self, -1)
self.length = 50
self.scale = 0.6
self.count = 5
self.size = wx.Frame.GetSize(self)
self.distance = self.size[1] / self.count
self.labellist = []
self.gaugelist = []
def ParseAndDisplay(self, data):
print "Successful access to main Frame class"
print 'And receive data: ', data
if MyFrame.firstrun == 0:
print 'First time run'
items = 3
for i in range(items):
self.labellist.append(wx.StaticText(self.panel,
-1, data+str(i),
(150, 50+i*20), (300,30)))
MyFrame.firstrun = 1
else:
self.labellist[0].SetLabel('AAA')//PROGRAM WILL ABORT
HERE!!!
self.labellist[1].SetLabel("Guo")
self.labellist[2].SetLabel("Qiang")
class NetUdp:
def __init__(self):
self.port = 8081
self.s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
self.s.bind(("", self.port))
print "Listening on port", self.port
def recvdata(self):
data, addr = self.s.recvfrom(1024)
return data
def netThread():
netudp = NetUdp()
while True:
data = netudp.recvdata()
frame.ParseAndDisplay(data)
if __name__ == '__main__':
firstrun = 0
app = wx.PySimpleApp()
frame = MyFrame()
frame.Show()
# start network thread first
id = thread.start_new_thread(netThread, ())
# main wxpython loop begins
app.MainLoop()
I know the code is ugly, but can anyone really save me here!
