How to add new checkButton

Hello,

I have a question about how to get the value of checkButton,

Down is my code,

In axis.tcl , I add a new menu learn . In menu_learn , I add a checkButton
.menu.learn add checkbutton \
-command edit_learn \
-variable ilc_check

In axis.py, I have to get the value from checkButton which is True or False
def edit_learn(*event):
if event == 1:
f = open('/home/A.txt', 'w')
f.write('hello1\n')
f.close()

Thanks!

You already have the examples you need in the 2 files you have altered

Search for the menu entry show_program, which is a toggle button value from a checkbutton, in axis.tcl

Then search for def show_program event handler in axis.py
You will see how to check the value of the variable.

Your code currently sets a variable ilc_check and then does not use it, instead trying to test whether the pointer *event == 1,
which it never will be.

An event pointer is a pointer to a struct giving info about the window event that initiated the call to the handler, it is nothing to do with the variable you set and you cannot get that info from it.
It contains things like
type
window
time
x
y
state
