[Tutor] sending stdout to a text box

[Bill Tolbert]

Well, a week has gone by and I've got to give this thing another try.

I have a script which works well; it sends messages to the console when
run from a prompt. How can I catch this and route it to a text box in
tkinter?

I've read about the textvariable and StringVar() option but I can't get it
to work. Text boxes don't support textvariable and I can't get the stdout
to redirect to anything useful.

Can someone help?

Here's the code:

#Adapted from TKTextDemo.py by Martin Stevens, budgester@budgester.com
#Shamelessly lifted from Useless Python (www.lowerstandard.com/python)


from Tkinter import *

class App:

##  Create GUI 

    def __init__(self, master):

        frame = Frame(master)
        frame.pack()
        self.t = StringVar()
	# this line doesn't work
        #self.text_box = Text(frame, textvariable=self.t)
        self.text_box = Text(frame)
        self.text_box.pack()
        
	# this call to dobackup works but no redirect of stdout
        self.dobackup = Button(frame, text="Do Backup",
				command=self.backup)

        self.dobackup.pack(side=TOP)

    def backup(self):
        import ICAREBackup
        #self.t = sys.stdout
        #sys.stdout = self.t
        self.text_box.insert(END, sys.stdout)
        ICAREBackup.ICAREBackup()

root = Tk()

app = App(root)

root.mainloop()
