Hi,

the follwing test ...

#!perl use strict; use warnings; use Tk; use vars qw/$TOP/; $TOP = MainWindow->new(); my $t = $TOP->Scrolled(qw/Text -scrollbars e/)->pack(); $t->insert('0.0', 'try **until **you **succeed'); my $result = $t->search(-forwards,"**",'end'); print "\$result: $result\n"; my $start=$result+.2; print "\$start: $start\n"; my @chars=$t->get("$start","$start wordend"); print "\nThe word:"; print"\n@chars\n"; MainLoop;
... with activePerl ...
# aperl -v This is perl, v5.6.1 built for MSWin32-x86-multi-thread (with 1 registered patch, see perl -V for more detail) Copyright 1987-2001, Larry Wall Binary build 633 provided by ActiveState Corp. http://www.ActiveState. +com Built 21:33:05 Jun 17 2002
... on XP did it, at least i think, as you want.

# aperl textwidget $result: 1.4 $start: 1.6 The word: until
But are sure whether it's a good idea to do text/string-orientated things with widget-methods. Perhaps it would be easier and more efficient to try approaches with regexes or split.

greetings, tos

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
