You can use the
search method to search the Text widget for a
pattern or regular expression. The
search method takes some optional
switches, the pattern to search for, and an index at which to start
$index = $text->search(
[switches], pattern, index, [ stopindex ])
If a match is made, the index returned points to the first character in the match. If no match is made, an empty string is returned.
Here is a simple example of using
$result = $text->search(-backwards => "find me", 'end'); $location = $text->search(-nocase => "SWITCHES", "1.0");
See Search Options for more information.
