Author The list of predefined colors in color chooser widget becomes empty

Hi All,

Please find the following independent application to reproduce the
issue.

click on check
click on choose color
===> Now check the predefined color in this dialog box. It is shown on
the left side.

choose a color and press ok
again click on check and choose color

===> Try to see the predefined colors. You will find none.


use strict;
use Tk;

my $newColor='';
my $mw=MainWindow->new(-title=>'SpyGlass Power Browser');
my $tl;
my $but=$mw->Button(-text=>'check',-command=>\&func)->pack;

sub func
{
$tl=$mw->Toplevel(-title=>'top level');
my $but2=$tl->Button(-text=>'choose color',-command=>\&func2)-
>pack;

}


sub func2
{
$newColor=$tl->chooseColor(-title=>"Choose Color for Range ",
-parent=>$tl);
$tl->destroy;
}

MainLoop;


I don't know whether the issue is there due to perl/tk installation.
Any help is appreciated.

Thanks in advance.
/Robert

On Windows, perl/Tk uses the native color chooser widget,
which varies depending on which version of Windows you are
running. On other OSes, it uses Tk::ColorEditor which does
not have a 'predefined' selection.

You can specify an '-initialcolor' attribute, if that helps.

An even smaller testcase directly from command line.

$ perl -MTk -MTk::ColorEditor -e '$mw=tkinit;$mw->ColorSelect->pack;$c=$mw->ColorSelect->pack;MainLoop'

This is now solved in the Perl/Tk SVN repository:

* solved chooseColor issue reported in
http://groups.google.com/group/comp...a1f994f532648be
(only first color dialog gets a color list)
* additional tests for ColorEditor
* make sure a destroyed waiting color dialog does not "block" the application
