NAME

Tk::TraceText - Text contents defined by a traced variable.

CONTENTS

SYNOPSIS



 $tt = $parent->TraceText(-option => value, ... );



DESCRIPTION

Create a new <B>TraceTextB> widget that is derived from the standard <B>TextB> widget. Because it inherits all the base options and methods it behaves just like a <B>TextB> widget. Additionally, <B>TraceTextB> 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.
<B>-textvariableB> 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 );
