NAME

6       Tk::TraceText - Text contents defined by a traced variable.
7

SYNOPSIS

9        $tt = $parent->TraceText(-option => value, ... );
10

DESCRIPTION

12       Create a new TraceText widget that is derived from the standard Text
13       widget. Because it inherits all the base options and methods it behaves
14       just like a Text widget.  Additionally, TraceText adds a -textvariable
15       option, which is a reference to a Perl scalar that defines the contents
16       of the widget.
17
18       Based on the Tcl/Tk TracedText "overridden widget" by Kevin Kenny.
19
20       -textvariable
21           A scalar reference.  The value of the variable defines the contents
22           of the TraceText widget.  Using the keyboard to insert or delete
23           text changes the value of the variable, and changing the variable
24           alters the contents of the TraceText widget.
25

METHODS

27       Standard Text widget methods.
28

ADVERTISED SUBWIDGETS

30       None.
31

EXAMPLE

33        my $tt = $mw->TraceText( -textvariable => \$scalar );
