( #3333=superdoc: print w/replies, xml ) Need Help??

I was just poking around in the Tk source (I think I'll be able to grok Lex Rex before I understand the Tk source) and it looks like there's no support for gridRemove in the code where I'd expect to find it. Maybe it was removed, or never added in the first place?

In Tk/ (I THINK this is part of the dispatch mechanism):

sub grid { local $SIG{'__DIE__'} = \&Carp::croak; my $w = shift; if (@_ && $_[0] =~ /^(?:bbox|columnconfigure|configure|forget|info|lo +cation|propagate|rowconfigure|size|slaves)$/x) { my $opt = shift; Tk::grid($opt,$w,@_); } else { # Two things going on here: # 1. Add configure on the front so that we can drop leading '-' Tk::grid('configure',$w,@_); # 2. Return the widget rather than nothing return $w; } }

Note that a direct call to &Tk::grid with the 'remove' argument works:

$ perl -MTk -e '$m=tkinit; $f=$m->Frame->pack; $b=$f->Button(-text=>"F +oo")->grid; $m->after(750,sub{Tk::grid("remove",$b)}); MainLoop'

This patch to Tk/ version 3.080 (Tk 800.024) seems to fix the problem for me:
