Hey all,
i am having an issue with my thread being called and then locking out
the gui.
i have been advised to follow a tutorial at the pygtk faq, and i think i
am close.
but still hanging.
first, i tried to use thread, then threading.
here is what i have.
import os
import time
from time import strftime
import sys
import gtk
import pygtk
import serial
import threading
from threading import Thread
import gtk.glade
gtk.gdk.threads_init()
def on_StartEnginesButton_clicked(self, widget, *args):
print "on_StartEnginesButton_clicked called with self.%s" %
widget.get_name()
Input1Iter = self.Input1Buffer.get_end_iter()
Input2Iter = self.Input2Buffer.get_end_iter()
Input1Data = 'Reading Serial device ttyS14 \n'
Input2Data = 'Reading Serial device ttys15 \n'
self.Input1Buffer.insert(Input1Iter, Input1Data)
self.Input2Buffer.insert(Input2Iter, Input2Data)
time.sleep(1)
def Serial1():
print 'running serial 1'
gtk.gdk.threads_init()
ser = serial.Serial('/dev/ttyS1', 2400, timeout=None)
loopy = 1
i = 1
while loopy < 5:
for x in range(5):
i = i + 1
a = ser.read(1)#read one byte
a = ord(a) # change byte to integer
if (a < 64 )or (a > 127):
break
b = ser.read(1)
b = ord(b)
if (b < 64 )or (b > 127):
break
c = ser.read(1)
c = ord(c)
if c < 92:
break
d = ser.read(1)
d = ord(d)
if d < 128:
break
Sensor_ID = (a & 63) + (b & 63) * 64 + (c & 1) * 4096
Status = (c & 62) / 2 + (d & 63) * 32
c = int(c)
d = int(d)
x_Now = strftime('%Y-%m-%d %H:%M:%S')
gtk.threads_enter()
Input1Data =
str(Sensor_ID)+'\t'+str(Status)+'\t--------->\t'+x_Now+'\n'
Input1Iter = self.Input1Buffer.get_end_iter()
self.Input1Buffer.insert(Input1Iter, Input1Data)
gtk.threads_leave()
f = open('/home/piv/PivData/tmp/Serial/'+str(i), 'w')
f.write(str(Sensor_ID)+'\n'+str(c)+'\n'+str(d)+'\n'+str(Status)+'\n'+x_Now)
f.close()
Thread.start(Serial1())
def main(self):
#gtk.gdk.threads_enter()
gtk.main()
#gtk.gdk.threads_leave()
def main():
main = Main()
main.run()
if __name__ == "__main__":
gtk.threads_enter()
main()
gtk.threads_leave()
thanks all , some (a lot) is not included here, as its rather long.
i have tried where the comments are , that didn't work either.
any ideas?
