bind all tkinter "bug" (Python)

Python recipe 580795 by Miguel Martínez López (all, bind, binding, tkinter). Revision 3.

This recipes tries to solve the problem of bind_all and unbind_all for tkinter.

When a callback is registered using bind_all method and later it's unregistered using unbind_all, all the callbacks are deleted for the "all" tag event. This makes difficult to register and unregister only one callback at a time. This recipes tries to solve this problem.

Observe the difference between the code below and the recipe. With the code below, when the user clicks nothing happens. But with my recipe it's possible to bind and unbind specific callbacks.

try:
    from Tkinter import Tk, Frame
except ImportError:
    from tkinter import Tk, Frame

root = Tk()
f = Frame(root, width= 300, height=300)
f.pack()

def callback1(event):
    print("callback1")

def callback2(event):
    print("callback2")

def callback3(event):
    print("callback3")

root.bind_all("<1>", callback1, add="+")
f.bind_all("<1>", callback2, add="+")
f.bind_all("<1>", callback3, add="+")

f.unbind_all("<1>")

root.mainloop()

Python recipe 577854 by Josh D (a, all, and, bash, be, command, completed, consume, file, first, generation, get, in, info, line, man, modify, must, only, pages, possibilties, possiblities, py, python, run, script, so, tab, terminal, the, this, to). Revision 6.

The script it self is very self explaining - the task is simple. *NIX only unless with cygwin perhaps?

To start this open a terminal and strike the "Tab" key to get all possibilities (strike y, and strike the space key alot). Select all then Copy and save in "comms.txt" Modify the file so ONLY the possiblities consume a line; no prompts or extra newlines. (first line must be a command, the last line must be a command)

Save the file ("~/Documents/bashing/comms.txt" is my path) then run this script in "~/Documents/bashing/".

This generates two (2) files: "bash_help_man.sh", "bash_help_info.sh".

Then it runs these files: "bash bash_help_man.sh", "bash bash_help_info.sh".

This produces 2 files for every command (every line) in "comms.txt". All manpages are wrote in "mans/", all infopages are wrote in "infos/"

There is now alot of files to read and organize; lets separate these by size. Directories are under1kb, under2kb, etc.

Once complete do as you wish the files less than 128 kb; these files are COPIED into there new respective home, I repeat COPIED.

The files 128 kb and higher ARE NOT copied to anywhere!
