Perl/Tk Pocket Reference
by Stephen Lidie


Following are the changes that were made in the 4/00 reprint:


(3) In the section on Perl/Tk callbacks,
Changed:
        Note that B<bind> callbacks are implicitly passed the bound widget
        reference as the first argument of the parameters list.
to:
        Note that B<bind> I<callbacks> are implicitly passed the bound object
        as the first argument of the parameter list.

Also changed:
        To prevent B<bind> from supplying an implicit widget reference
        to the callback use this form:
to:
        To prevent B<bind> from supplying an implicit object reference
        to the I<callback>, specify your own object as the first element of
        the array:


(5) Under the -relief option, added "solid" as a valid value.


(10) In the description of the Canvas bind() command, added this sentence:
	"Use the B<CanvasBind> method to create a binding for the 
	canvas as a whole."


(31) The sentence "Set state of default ring" now reads
     "Set state of default string".  


{49} in -data description:
changed:
	"Specifies a string" to "Specifies a Perl scalar"


{62} Removed the italics from "selectionSet"


{72} Changed:
        @ISA = qw/Tk::Derived Tk::SomeWidget/;
to:
        use base qw/Tk::Derived Tk::SomeWidget/;


(85) Changed the first sentence of section 15, Bindings and Virtual Events, 
to this:

       Note that B<bind> I<callbacks> are implicitly passed the bound object
       as the first argument of the parameter list.  


(86) The syntax line for eventAdd() had a superfluous constant-width-font
     character "t".  Removed the "t" so that

            tI<virtual> became simply I<virtual>

(93) The "component" parameter to B<findINC> is now in italics rather than
         constant width font.


{93} The Busy() command has an optional -recurse parameter.
Changed entry to:
	$widget->Busy (-recurse => 1);
              	Changes cursor to a watch until B<Unbusy> is called.  If
		CW<-recurse> is true, descend the widget hierarchy and 
		change all cursors.


(99) Incorrect index entries:

        geometry, 79,, 83       is now       geometry, 79, 83, 88


(100) Incorrect index entries:

        Subwidget, 72           is now       Subwidget, 74
	Text, 8                 is now       Text, 24
        Toplevel, 73            is now       Toplevel, 39
