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 );
