change color of text box in Perl/Tk

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

I am using Perl and Tcl/Tk to build a GUI and I ahve run into a question. When I have a checkbutton and I want that checkbutton, when checked in the GUI, to change the color of a text box from gray to white how do I do this particular action? I have tried, poorly, to use bind on the action of <Button-1> and this doesn't get me there. Any suggetions would be great.

When you declare the Checkbutton, you would want to have the handle for the text box to be in scope, so you can refer to that in a sub, to be assigned to the Checkbutton's "-command" attribute -- something like the following: `$txtbox = $textParent->Text(...)->pack(); ... $cbtnParent->Checkbutton(-variable => \$txtboxColor, -text => 'Set textbox color', -offvalue => 'gray', -onvalue => 'white', -command => sub {$txtbox->configure(-backgrou +nd => $txtboxColor)} )->pack(); # (or whatever geometry mgmt you'r +e using)` [download]	[reply] [d/l]
