is located.  Should a match not be found the match point is {}.  The

option is meant to be used as a means of notification that the

find operation has completed and allow other actions to take place

.SH DESCRIPTION

.PP

The \fBfinddialog\fR command creates a find dialog that works in

conjunction with a text or scrolledtext widget to provide a means

of performing search operations.  The user is prompted for a text

pattern to be found in the text or scrolledtext widget.  The

search can be for all occurances, by regular expression, considerate

of the case, or backwards.

.SH "METHODS"

.PP

The \fBfinddialog\fR command creates a new Tcl command whose

name is \fIpathName\fR.  This

command may be used to invoke various

operations on the widget.  It has the following general form:

.DS C

\fIpathName option \fR?\fIarg arg ...\fR?

.DE

\fIOption\fR and the \fIarg\fRs

determine the exact behavior of the command.  The following

commands are possible for finddialog widgets:

.SH "WIDGET-SPECIFIC METHODS"

.TP

\fIpathName \fBcget\fR \fIoption\fR

Returns the current value of the configuration option given

by \fIoption\fR.

\fIOption\fR may have any of the values accepted by the \fBfinddialog\fR

command.

.TP

\fIpathName \fBclear\fR

Clears the pattern in the entry field and the pattern matchin

indicators in the text or scrolledtext widget.

.TP

\fIpathName\fR \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR?

Query or modify the configuration options of the widget.

If no \fIoption\fR is specified, returns a list describing all of

the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for

information on the format of this list).  If \fIoption\fR is specified

with no \fIvalue\fR, then the command returns a list describing the

one named option (this list will be identical to the corresponding

sublist of the value returned if no \fIoption\fR is specified).  If

one or more \fIoption\-value\fR pairs are specified, then the command

modifies the given widget option(s) to have the given value(s);  in

this case the command returns an empty string.

\fIOption\fR may have any of the values accepted by the \fBfinddialog\fR

command.

.TP

\fIpathName \fBfind\fR

Search for a specific text string in the text widget given by

the -textwidget option.  This method is the standard callback

for the Find button.  It is made available such that it can be

bound to a find again action.
