Re: editable text + syntax for addTextFramePage

Update: two small changes in Tk/Wizard.pm i.e. require Tk::TextHighlight; and in sub _text_frame .... and I have syntax coloring!

That's not nice :) you're not supposed to edit modules directly. You're supposed to copy _text_frame and change it to suit your needs, one way

$wizard->addPage( sub { MyTextFrame( $wiz ); } );

...


sub MyTextFrame {
    package Tk::Wizard; ## for DEBUG/WARN/Dumper...
    my $self = shift;
    my $args = shift;

    DEBUG "Enter _text_frame with ", Dumper($args);
    my $text;
    my $frame = $self->blank_frame(%$args);
    if ( $args->{-boxedtext} ) {
        if ( ref $args->{-boxedtext} eq 'SCALAR' ) {
            $text = $args->{-boxedtext};
        }
        elsif ( not ref $args->{-boxedtext} ) {
            open my $in, $args->{-boxedtext}
                or Carp::croak "Could not read file: $args->{-boxedtex
+t}; $!";
            read $in, $$text, -s $in;
            close $in;
            WARN "Boxedtext file $args->{-boxedtext} is empty." if not
+ length $text;
        }
    }
    $$text = "" if not defined $text;
    my $t = $frame->Scrolled(
        "TextHighlight",
        -syntax => ( $args->{ -syntax } || 'Perl' ),
        -background => ( $args->{ -background } || 'white' ),
        -relief => "sunken",
        -borderwidth => "1",
        -font        => $self->{defaultFont},
        -scrollbars  => "osoe",
        -wrap        => "word",
    )->pack(qw/-expand 1 -fill both -padx 10 -pady 10/);

    $t->configure( -background => 'green' ) if DEBUG_FRAME;
    $t->insert( '0.0', $$text );
##  $t->configure( -state => "disabled" );

    return $frame;
}

the other way is monkeypatching (declaring a subroutine in someone elses package)

$wizard->addPage( sub { $wiz->MyTextFrame; } );

sub Tk::Wizard::MyTextFrame { ...
[download]

Can't edit though, and not sure if this breaks something else. Same happens with Tx::CodeText

When a widget is diabled, its disabled :) Remove

  $t->configure( -state => "disabled" );

This disabled bit from sub _text_frame looks like a bug in Tk::Wizard, it doesn't make sense to disable ROText, its already read-only :)

Thank you for the "monkey patching" hint, used it and the solution to make text editable is quite simple: `use Tk::TextUndo; use Tie::Tk::Text; sub Tk::Wizard::_my_text_frame { #... my $t = $frame->Scrolled( "TextUndo", )->pack; if ( $args->{-variable} ) { tie @{$args->{-variable}}, 'Tie::Tk::Text', $t; } #... }` [download] which can be called as `$wiz->_my_text_frame( { -title => 'editable text', -boxedtext => \$originaltext, -variable => \@editedtext } );` [download]	[reply] [d/l] [select]

use Tk::TextUndo;
use Tie::Tk::Text;
sub Tk::Wizard::_my_text_frame {
#...
 my $t = $frame->Scrolled(
  "TextUndo",
 )->pack;
 if ( $args->{-variable} ) {
  tie @{$args->{-variable}}, 'Tie::Tk::Text', $t;
 }
#...
}

$wiz->_my_text_frame(

   -title     => 'editable text',
   -boxedtext => \$originaltext,
   -variable => \@editedtext
 }
