I'm working on a Perl/Tk GUI application that displays data coming from another Perl program. The GUI consists of many gKrellM-style graphs and status bar indicators. I'd like to update the graphs as new information comes in (in this case, constantly) without freezing the GUI. So I need some way to trigger Tk events as new information comes from the pipe. I was going to use Tk file events, but apparently these do not work under Windows (the target platform in this case). Is this true and if so, what are my alternatives?

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).

are good places to start.
