.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\ \fBuse Tk::TextUndo;\fR

\&\ \fI$testundo\fR = \fI$parent\fR\->\fBTextUndo\fR(?\fI\-option\fR=>\fIvalue\fR, ...?);
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This IS-A text widget with an unlimited 'undo' history but without
a re'undo' capability.
.Sh "Bindings"
.IX Subsection "Bindings"
The \f(CW\*(C`TextUndo\*(C'\fR widget has the same bindings as the Text widget.
In addition there are the following bindings:
.IP "Event <L4> <<Undo>>" 4
.IX Item "Event <L4> <<Undo>>"
undo the last change.  Pressing <L4> several times undo
step by step the changes made to the text widget.
.Sh "Methods"
.IX Subsection "Methods"
The \f(CW\*(C`TextUndo\*(C'\fR widget has the same methods as \f(CW\*(C`Text\*(C'\fR widget.
Additional methods for the \f(CW\*(C`TextUndo\*(C'\fR widget are:
.IP "$text\->Load($filename);" 4
.IX Item "$text->Load($filename);"
Loads the contents of the \f(CW$filename\fR into the text widget. \fILoad()\fR
delete the previous contents of the text widget as well as it's
undo history of the previous file.
.IP "$text\->Save(?$otherfilename?)" 4
.IX Item "$text->Save(?$otherfilename?)"
Save contents of the text widget to a file. If the
\&\f(CW$otherfilename\fR is not specified, the text widget contents
writes the file of \f(CW$filename\fR used in the last \fILoad()\fR
call.  If no file was previously \fILoad()\fR'ed an error message
pops up.  The default filename of the last \fILoad()\fR call
is not overwriten by \f(CW$otherfilename\fR.
.IP "$text\->FileName(?$otherfilename?)" 4
.IX Item "$text->FileName(?$otherfilename?)"
If passed an argument sets the file name associated with the loaded
document. Returns the current file name associated with the document.
