Re: Tk::Hlist questions

Hmmm... interesting question.  There is of course, more than one way to do it.
You could use recursion to get the total number of entries in the list.  i.e. get
the children of the top level and recurse through each one, returning a count
of all the children...  I can't be positive, without looking at the source, but the
HList doesn't seem to have a method for this, so you need to roll your own.

One way to get either column 0 or all columns would be to use a hash of
anonymous arrays.  The key to the hash being the HList entryPath they
are stored under...

$col0 = ${$hash{$entryPath}}[0];

@cols = @{$hash{$entryPath}};

or somesuch...  You of course have to build the hash as you add elements to
the HList.

To answer your last question, I believe you need to create an ItemStyle
for each group of settings.  (i.e. black text on yellow bg is one style, green
text on black bg is another...)  This example uses the hex representation
for the color (since there wasn't a close enough match):

    $idleBG = $hList->ItemStyle( 'text', -background => '#8f6f8f' );

Then you use it like

    $hList->itemCreate(
                    $entry,
                    $col,
                    -itemtype => 'text',
                    -text     => 'foo',
                    -style    => $idleBG,
                    );


Hope this helps.
