I have a Button and a Text Widget. When a user click the Button, I want to know if the text in the Text Widget has been modified since the last time the user clicked the Button.
How do I check this?

Save the text at each button press and compare it to the snapshot of the previous button press? – Peter Lewerin Jan 24 '14 at 11:39

I know that method, but is there a simpler way? – Liam Willis Jan 24 '14 at 11:42

The invocation
$t edit modified
(where t holds the pathname of your text widget) should tell you if the text widget has been modified. Reset with
$t edit modified false
or whatever the corresponding Perl-Tk is.
