Widget Type

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

Is there a widget in Tk that will display the value of a variable but allow the user to type in a new value, if desired, over the original value in the widget and have the new value saved to the variable?

You can associate widgets with variables, and they'll take on the value of that variable. You probably need something like a `LabEntry` or an `Entry` widget (depending on what you're doing with it) - and you'd use it something like this: `my $mw = new MainWindow(); my $text = "This is an entry box"; $entry = $mw->Entry(-textvariable => \$text)->pack();` [download] That'll give you a text entry box, containing the text in `$text`, and allow you to change the text. Anything the user enters will automatically be stored in the `$text` variable. Hope that helps. -- Foxcub `#include www.liquidfusion.org.uk` Edit: Corrections/clarifications.	[reply] [d/l] [select]
