You used the checkbutton with a linked variable: -variable ::tkpoint::x
then this global variable store the current value, use
$::tkpoint::x

If you assign other value (like set ::tkpoint::x 1), the checkbutton will also reflect this result

Hi!

I have defined a checkbutton like this:

set c1 [checkbutton $parent.c1 -text "X:" -variable tkpoint::x ]

proc ::tkpoint::setvarx { } {
global ProblemTypePriv
variable x
set x $value
return ""
}

How can i get the value 0 or 1 (checkbutton selected or deselected)?
If checkbutton is selected i introduce one value in a table; if is deselected i don't introduce nothing.

It's possible to obtain that values?

$c1 *** ?

Thank you.
