[Tutor] using TK to view an image and then close the window

[Ertl, John]

All,

I have been struggling with being able to view an image and most things have
not worked for one reason or another so I am trying to fall back on a way I
used to do it in PERL.  Use TK to show the image.  I do not know TKInter but
I have two scripts one that gets a list of images and anouther that displays
them using Tkinter.   This is basically how I would like to use it...I am
going to be using PIL to manipulate the image (and show() does not work) so
I just want a quick view to see how it looks.  I can get the image to show
up and minimize and maximize but I can not get the window to close and then
display the next image.  

I have tired several things but no luck. 

Any help on getting the TK window to shutdown cleanly would be appreciated.
Thanks

(X) does not work.
import Image
import Tkinter,ImageTk

def TKview(img,mainTitle="image"):
        
        app = Tkinter.Tk()
        app.withdraw()

        top = Tkinter.Toplevel(app,visual="truecolor",colormap="new")
        top.title(mainTitle)
        top.protocol("WM_DELETE_WINDOW", quit)
        top.bind("<q>",quit)
        top.bind("<Q>",quit)

        canvas = Tkinter.Canvas(top)
        canvas.pack()

        p = ImageTk.PhotoImage(img)

        canvas['width'] = img.size[0]
        canvas['height'] = img.size[1]

        canvas.create_image(0,0,anchor='nw',image=p)

        top.mainloop()

def quit(event=None):
        top.destroy()
        top.quit()
</CODE>

<CODE># this code gets the images opens them and calls the TK code above to
display them

import glob
import thread
import Image

import TKviewTest # the module to view the images

       
gifList = glob.glob("./*.gif")
print gifList
for image in gifList:
       image = image[2:] # glob leaves ./ in file name

       newIm    = Image.open(image)

       TK = TKviewTest
       thread.start_new_thread(TK.TKview(newIm,mainTitle="image"))

</CODE>
