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 );
