Python Tkinter: Text widget unbind mouse wheel

Question

I currently have a GUI that uses the Text widget, and I realize mouse wheel can be used to scroll up and down the Text widget.

However, I already have a scroll bar for that task, and I am planning to use mouse wheel for other tasks. So how do you unbind this event from Text widget?

Example code:

from Tkinter import *

def onclick():
   pass

root = Tk()
text = Text(root)
text.insert(INSERT, "Hello.....")
for _ in range(1000):
   text.insert(END, "Bye Bye.....")
text.pack()

text.tag_add("here", "1.0", "1.4")
text.tag_add("start", "1.8", "1.13")
text.tag_config("here", background="yellow", foreground="blue")
text.tag_config("start", background="black", foreground="green")
root.mainloop()

Answer 1

return 'break' in the callback will override the default behavior. Just bind the <MouseWheel> event to the text widget:

def scrollwheel(event):
    return 'break'

text.bind('<MouseWheel>', scrollwheel)
