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

Subject: [GiDlist] Know if checkbutton is selected
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.
