Hi there,
after reading TkInter/thread -recipe:
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/82965
I wondered if it was possible to avoid using threads
for the following problem:
I have script started from W2K console that normally
prints ascii messages to the screen. However, I have
command line "debug" -flag that might cause printing
of UTF-8 data to the screen. This fails occassionally
due to Console encoding, of course.
What I need is Tkinter window where some printouts
are directed when script is run in Debug -mode
(Redirection of stdout is out of question).
While testing, I have got this far already:
---script starts----
from Tkinter import *
from ScrolledText import ScrolledText
import os, sys, tkFont, codecs
class Pyg_message_box:
def __init__(self, parent):
self.myParent = parent
self.myContainer1 = Frame(parent)
self.myContainer1.option_add("*font",\
tkFont.Font(family="Arial Unicode MS", size=8))
self.myContainer1.pack()
self.text = ScrolledText()
self.text.pack()
self.button1 = Button(self.myContainer1, text="Quit",\
command=self.button1Click)
self.button1.pack(side=LEFT)
self.button1.bind("<Button-1>", self.button1Click)
def button1Click(self, event):
self.myContainer1.quit()
def write(self, s):
self.text.insert(END, s)
root = Tk()
widget = Pyg_message_box(root)
sys.stdout = widget
a = codecs.open("d:\\test.txt", "r", "utf_16").readlines()
for x in a:
print x
root.mainloop()
---script ends----
My questions are:
- Can I open Tk -window without enclosing the whole script
between "root=Tk()" and "root.mainloop()"?
- What is the idiom of opening Tk -window only when Debug -flag
is encountered (the script stops running until window is closed)?
Something like:
if not my_debug == "ON":
print "message" # prints to console
else:
# 1) open temporary ScrolledText() Tk -window
# 2) Print stuff to window
# 3) Ask user to close window
I would no like to always open Tkwindows just in case user runs script
with debug -flag on.
