Hi Joe,
the image won't refresh until you explicitely tell Tk to do so, so you would
have to do some more
in newPic(); btw, it looks overly complicated to me to use a "Data" class where
a simple variable
will do the trick, so I would suggest to change the code like this:
pics = os.listdir(imgDir)
pics.remove('license.txt')
pics.remove('gacor.py')
print "There are %s saved images in the image folder." % len(pics)
pic = 0
root = Tk()
root.title("GaCoR Image Browser")
app = Frame(root)
app.grid()
imgPrep = ImageTk.PhotoImage(file=os.path.join(imgDir, pics[pic]))
imgShow = Label(app, image=imgPrep).grid()
info = Label(app, text="Displaying %s" % pics[Data.pic])
info.grid()
def newPic():
global pic
pic = pic + 1
imgPrep.configure(file=os.path.join(imgDir, pics[pic]))
Button(app, text="Next Image", command=newPic).grid()
Button(app, text="Close", command=quitProg).grid()
app.mainloop()
I hope this helps
Michael
