Heys all,

I'm trying to write a script which involves a large number of pairs of Tk labels and entry boxes. I've written a sub to create each pair, pointing the textvariable to a hash, meaning to create a hash of entry box data keyed on a given key.

However, I do not seem to be able to get information out of the entry box hash - it seems that the data is not being assigned there in the first place. Can anyone see a way to solve this, or if what I am trying to do is not possible, is there an alternative solution? (would a global hash work?)

My code to create each label/entry box pair is below:

sub labelledEntry {
    my ($_objects, $objkey, $label, $width, $container) = @_;
    my %objects = %$_objects;
    $container -> Label( -text => $label ) -> pack( -side => 'left' );
    $container -> Entry( -width => $width, -textvariable => \$objects{
+$objkey} ) -> pack( -side => 'right' );

    return \%objects;
}

and the code I'm using to get data out of the hash (the button code and subroutine to output it) is as follows:

$searchFrame -> Button( -text => 'search', -command => [ \&search, \$o
+bjects{searchstr} ] )->pack( -side => 'left' );


sub search
{
    my $text = shift;
    print STDERR $text;
}

Any advice would be appreciated.
