Re: Tk hidden binding

As far as I can tell, this is a bug in Tk :) Run one of these and type Ctrl+[

perl -MTk -le " tkinit->Text->pack->focus; MainLoop; "

perl -MTk -le ' tkinit->Text->pack->focus; MainLoop; '
[download]

or type Ctrl+] and you'll get esc(\033) and gs(\035) respectively

This is a bug

$ perl -MTk -le " print for Tk->VERSION, $^V "
804.0295
v5.12.2


$ perl -MTk -le " print for Tk->VERSION, $] "
804.028
5.008009
[download]

Ctrl+g results in bel(\a)

This isn't supposed to happen :)

Checking the Tk bug cue i find Bug #47173 for Tk: "Modifier" key releases don't track key presses correctly

perl/Tk is built upon Tcl/Tk 8.5.7

Tcl/Tk 8.6 doesn't have this problem

#!/usr/bin/perl --
use strict;
use warnings;
use Tcl::pTk;
my $int = new Tcl::pTk;
$int->Eval(<<'EOS');
# pure-tcl code to create widgets (e.g. generated by some GUI builder)
text .e
## http://wiki.tcl.tk/1626#tk_version
.e insert end "tcl_version      $tcl_version\n"
.e insert end "tcl_patchLevel   $tcl_patchLevel\n"
.e insert end "tk_version       $tk_version\n"
.e insert end "tk_patchLevel    $tk_patchLevel\n"
.e insert end "tk_library       $tk_library\n"
pack .e
EOS
my $e = $int->widget('.e');     # get .e entry into play
$e->insert( "end", "
Tcl::pTk $Tcl::pTk::VERSION
Tcl $Tcl::VERSION
\$^V $^V
\$] $]
");
$int->MainLoop;
__END__
tcl_version      8.6
tcl_patchLevel   8.6b1.2
tk_version       8.6

On my Tk (Tk-804.029_500) a <control ]> prints a # character to the Text area. I don't know for sure if this is what is normal or not, I'm running Slackware 1337 for AMD64 , if that makes any difference in keyboard setups. I'm not really a human, but I play one on earth.

I think it is not normal , I've yet to see a toolkit where a text widget does that by default going back some 20 years :) Nice catch with the subwidget in Re^3: Tk hidden binding, I also get the same thing you describe	[reply]

Would that be the the xmodmap? I'm not really a human, but I play one on earth. Old Perl Programmer Haiku ................... flash japh	[reply]

It's amazing how things can get complicated quickly. I get \x{1b} and \x{1d}. Thank you for the various informations in your answer.	[reply]

Ah ok, yes almost the same, just an openness detail: `perl -le " print qq[\033\035] " \|od -tacx1 0000000 esc gs nl 033 035 \n 1b 1d 0a 0000003` [download]	[reply] [d/l]
