How can I find out whether a Checkbox is checked or unchecked in Ruby?
Here is my Checkbox definition (hope it is correct):
How can I find the state of the checkbox? I tried the .value
member (like in the entry field), but this is not defined
I have searched several tutorials on Ruby/Tk, but did not find
one which covers checkboxes. Is there a reference manual
available, or man pages, which covers the Tk extensions of Ruby?
