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.
None.
EXAMPLE¶
my $tt = $mw->TraceText( -textvariable => \$scalar );
