Hi Perl Monks,
I have a perl script which makes use of Tk

main.pl
use Tk;
.
.
.
.
sub s1
{
  require p1.pl;
  require p2.pl;
  require p3.pl;
  require p4.pl;
.
.
.
.}
1;
.
.
.
[download]

p1.pl,p2.pl,p3.pl,p4.pl contain subroutines which are called within subroutine s1.

As a further level of nesting,in p3.pl

p3.pl
.
.
.
sub s2
{
 require p5.pl;
 require p6.pl;
 require p7.pl;
 require p8.pl;
.
.
.
}
1;
.
.
.
[download]

p5.pl,p6.pl,p7.pl,p8.pl contain subroutines which are called within subroutine s2.

I had written all the code in parts, i.e. all the lower level subs first and then combined
the entire code using require statements.

The code was working fine this way.When I put all the subroutines in main.pl itself and removed
the require statements, I got a lot of Tk errors:

Tk::Error: Can't call method "insert" without a package or object reference at C:\monisha\project\Appliw\s.pl line
124, <EDINP> line 1.
\&main::replace1
(menu invoke)

Tk::Error: Tk::Label=HASH(0x23b8818) is not a Tk object at D:/Perl/site/lib/Tk.pm line 91, <EDINP> line 1.
Tk callback for tkwait
(command bound to event)

Tk::Error: Can't call method "get" without a package or object reference at C:\monisha\project\Appliw\s.pl line 46,
<EDINP> line 1.
\&main::tged

Line 124 is this:

$t->insert('sel.first',"$chosen1");

Line 46:

@chars=$t->get('sel.first','sel.last');

What is the problem here?
Please help.Thanx
:)

• 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).
