(I apologize if this posts twice. My AVG is being fussy.) From what I've read, MouseWheel is a very tricky event. I have replaced my Python tcl84.dll and tk84.dll files with those in the ActiveTcl distribution to fix the crashes caused by the event. Then, I managed to see that my test script (see code below) was registering the event by printing the delta value (+/- 120).
----------------- from Tkinter import * def reportScroll(event): print "scrolled", event.delta, event root = Tk() myListbox = Listbox(root, selectmode=SINGLE, height=10, width=20) for x in range(30): myListbox.insert(END, x) myListbox.pack(side=LEFT, expand=YES, fill=BOTH) myScrollbar = Scrollbar(root, command=myListbox.yview) myScrollbar.bind('<MouseWheel>', reportScroll) myScrollbar.focus_set() myScrollbar.pack(side=RIGHT, fill=Y) myListbox.config(yscrollcommand=myScrollbar.set) root.mainloop() ----------------- The scrollbar and listbox are tied together, but moving the wheelmouse does nothing. I realize the code above doesn't give the event any real duties, but I'm not really sure how to make that leap. How and to what do I bind <WheelMouse> so that it will affect the listbox and the scrollbar? -- http://mail.python.org/mailman/listinfo/python-list
