:) Ignoring all the issues with your code with short-circuit sub section_del {
return $Section_tblw->clear;
looks like Tk::Table is not deleting checkboxes
so I replace that with return my_clear( $Section_tblw ); and one or three dd-Dumper-ings later, its an off-by-one error in clear
sub my_clear {
my $self = shift;
my $rows = $self->cget( -rows );
my $cols = $self->cget( -columns );
## 1st row is labels
foreach my $r ( 1 .. $rows ) {
#~ foreach my $c ( 1 .. $cols ) {
## 1st column is 1st column
foreach my $c ( 0 .. $cols ) {
my $old = $self->get( $r, $c );
next unless $old;
$self->LostSlave( $old );
$old->destroy;
}
}
$self->_init;
$self->QueueLayout( Tk::Table::_SlaveSize() );
} ## end sub my_clear
I imagine the OBO error migt stem because at one point the first column in each row might have been a counter (nth row) ...

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).
