[issue27405] Ability to trace Tcl commands executed by Tkinter

[Terry J. Reedy]

Terry J. Reedy added the comment:

Much better.  I can more or less follow IDLE startup.
>>> import tkinter
>>> tkinter.debug
False
>>> tkinter.debug = True
>>> import idlelib.idle
proc tkerror {} {<function _tkerror at 0x038479F8>}
proc exit {} {<function _exit at 0x03847A58>}
proc 27305592destroy {} {<bound method CallWrapper.__call__ of <tkinter.CallWrapper object at 0x04033658>>}
wm protocol . WM_DELETE_WINDOW 27305592destroy
wm withdraw .
wm iconbitmap . -default F:\\Python\\dev\\36\\lib\\idlelib\\Icons\\idle.ico
tcl_wordBreakAfter {a b} 0
set tcl_wordchars [a-zA-Z0-9_]
set tcl_nonwordchars [^a-zA-Z0-9_]
tk windowingsystem  
menu .`menu
toplevel .`listedtoplevel -menu .`menu
wm iconname . None
wm iconname .`listedtoplevel {}
wm title . None
wm title .`listedtoplevel idle
...
proc 67104888handler {} {<bound method CallWrapper.__call__ of <tkinter.CallWrapper object at 0x05727690>>}
bind .`listedtoplevel.`frame.text <Control-KeyPress> if\ \{"[67104888handler\ %#\ %b\ %f\ %h\ %k\ %s\ %t\ %w\ %x\ %y\ %A\ %E\ %K\ %N\ %W\ %T\ %X\ %Y\ %D]"\ ==\ "break"\}\ break\
... # lots of above, binding for Shell window. Default print is noisy.
    # I presume a custom handler that recognizes 'proc' could be better.

menu .`menu.file -tearoff 0
.`menu add cascade -label File -menu .`menu.file -underline 0
... # menu for Shell
.`menu.file add command -label {New File} -underline 0 -command 62029624command -accelerator Ctrl+N
... # more menu - new names **really** help!!!

Will ...settrace(None)?  Aside from that, I would like to see this in 3.6. (ie, applied now, upgraded later, if definitely safe).  (Note: 4AM here, so this is best I can review now ;-).
