Try passing your array as a ref to your sub:
my @info;
my $button_submit = $lf->Button(
-text => 'Search',
-command => [\&get_data, \@info],
)->pack(qw//);
...this should pass the \@info ref into your get_data sub. You can also add your Tk widget as another parameter and call configure on that ref.
my @info;
my $button_submit = $lf->Button(
-text => 'Search',
-command => [\&get_data, \@info, $TkWidget],
)->pack(qw//);
...
sub get_data {
my ($info_ref, $tkwidget_ref) = @_;
# add/delete/modify elements of $info_ref
# call configure on the widget
$tkwidget_ref->configure(...);
}
This is the method I use when I want to modify a data structure using a callback.

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).
