Hello Monks,

I searched here for Tk::Tree and did not find a relevant article, CPAN, and O'Reilly ... but the answer is elusive.

I am able to populate a Tk::Tree with a structure, and after some processing, I would like to change the color of an entry is the tree - but I can't get the call and syntax right.

Here's the sample Tk::Tree code:

use Tk;

use Tk::Tree;

my $mw = MainWindow->new(-title => 'Tree');

my $tree = $mw->Tree->pack(-fill => 'both', -expand => 1);

foreach (qw/orange orange.red orange.yellow green green.blue green.yel
+low purple purple.red purple.blue/)
{
  $tree->add($_, -text => $_);
}


# Different things to try here


$tree->autosetmode();

MainLoop;

1. Try itemConfigure:

$tree->itemConfigure('orange.red', 0, -foreground => 'blue');
[download]

Error:

Bad option `-foreground' at C:/Strawberry/perl/site/lib/Tk.pm line 251
+.

2. Try itemConfigure with a '1' since altering orage.red would be in column 1 of a HList:

$tree->itemConfigure('orange.red', 1, -foreground => 'blue');
[download]

Error:

Column "1" does not exist at C:/Strawberry/perl/site/lib/Tk.pm line 25
+1.
[download]

3. OK. Try option -fill instead of -foreground because of other observed inconsistencies in Tk:

$tree->itemConfigure('orange.red', 0, -fill => 'blue');
[download]

Error:

Bad option `-fill' at C:/Strawberry/perl/site/lib/Tk.pm line 251.
[download]

I've tried configure, itemConfigure, entryConfigure (that's for menus) and I'm just not getting it right.

Please help!
