Hi there,
got it. Note the root.distroy()-command.

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.
