NAME
Tk::TraceText - Text contents defined by a traced variable.
SYNOPSIS
$tt = $parent->TraceText(-option => value, ... );
DESCRIPTION
Create a new TraceText widget that is derived from the standard Text
widget. Because it inherits all the base options and methods it behaves
just like a Text widget. Additionally, TraceText adds a -textvariable
option, which is a reference to a Perl scalar that defines the contents
of the widget.
Based on the Tcl/Tk TracedText "overridden widget" by Kevin Kenny.
-textvariable
A scalar reference. The value of the variable defines the contents
of the TraceText widget. Using the keyboard to insert or delete
text changes the value of the variable, and changing the variable
alters the contents of the TraceText widget.
METHODS
Standard Text widget methods.
ADVERTISED SUBWIDGETS
None.
EXAMPLE
my $tt = $mw->TraceText( -textvariable => \$scalar );
