disabling the Listbox widget in Perl/Tk

bobdeath has asked for the wisdom of the Perl Monks concerning the following question:

I am working on a project where I need to disable a Perl/Tk listbox widget. Most widgets have a -state option that I can set to disabled, but the Listbox widget doesn't seem to have this option. Can any monks out there enlighten me as to how I would go about disabling this widget?

The way I have done it is to gray the box manually and disable all the bindings: `$listbox->configure(-foreground => $grayout_color); # Disable all bindings. foreach my $seq ($listbox->bind()) { my $code = $listbox->bind($seq); # Store the $code somewhere... # if you want to re-enable later. $listbox->bind($seq, ""); }` [download]	[reply] [d/l]

The Tix-based `Tk::TList` widget supports the -state option. The TList widget class includes a lot more functionality than Listbox, but you should be able to use it with only minor modifications to your code.	[reply] [d/l]

Possibly not what your looking for but the Tk::HList widget allows you to disable individual elements: `$hlist->entryconfigure($entryPath, -state => 'disabled');` [download] -- Life is a tale told by an idiot -- full of sound and fury, signifying nothing.
