I tried to make a program which on a button click,starts reading from a file
and then shows contents in different text fields.However i am not able to do
that properly.I have attached two attempts.How can i do the above task.
#!/usr/bin/env python
#Program to show text entries
import pygtk
pygtk.require('2.0')
import gtk
import serial
import re
class Entry:
#ser=serial.Serial()
#ser.port="/dev/ttyUSB0"
#ser.baudrate=9600
#ser.open()
def callback(self,widget,entry):
g=open('/home/nipun/1.txt')
vars = re.compile('^(\d+\.?\d*)a(\d+\.?\d*)b(\d+\.?\d*)c(\d+\.?\d*)d(.*)')
i=0
while(i<3):
s=g.readline()
print s
#g.write(s)
#g.write("\n")
#print "\n"
m = re.search(vars, s) # Run the regexp on the packet
var2 = m.group(2)
var1 = m.group(1) # take out the values
var3 = m.group(3)
var4 = m.group(4)
print var1,"\n"
al=str(12)
entry.set_text(al)
entry1.set_text(var2)
entry2.set_text(var3)
entry3.set_text(var4)
