</pre><H2>DESCRIPTION</H2>
<P>
The <B>finddialog</B> 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.

</pre><H2>METHODS</H2>
<P>
The <B>finddialog</B> command creates a new Tcl command whose
name is <I>pathName</I>.  This
command may be used to invoke various
operations on the widget.  It has the following general form:
<pre>
<I>pathName option </I>?<I>arg arg ...</I>?
</pre>
<I>Option</I> and the <I>arg</I>s
determine the exact behavior of the command.  The following
commands are possible for finddialog widgets:

</pre><H2>WIDGET-SPECIFIC METHODS</H2>
<DL>
<DT> <I>pathName <B>cget</B> <I>option</I>
</I></B>
<DD> Returns the current value of the configuration option given
by <I>option</I>.
<I>Option</I> may have any of the values accepted by the <B>finddialog</B>
command.
</DL>
<DL>
<DT> <I>pathName <B>clear</B>
</I></B>
<DD> Clears the pattern in the entry field and the pattern matchin 
indicators in the text or scrolledtext widget.
</DL>
<DL>
<DT> <I>pathName</I> <B>configure</B> ?<I>option</I>? ?<I>value option value ...</I>?
</I></B>
<DD> Query or modify the configuration options of the widget.
If no <I>option</I> is specified, returns a list describing all of
the available options for <I>pathName</I> (see <B>Tk_ConfigureInfo</B> for
information on the format of this list).  If <I>option</I> is specified
with no <I>value</I>, 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 <I>option</I> is specified).  If
one or more <I>option-value</I> 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.
<I>Option</I> may have any of the values accepted by the <B>finddialog</B>
command.
</DL>
<DL>
<DT> <I>pathName <B>find</B>
</I></B>
<DD> 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.
