.SH DESCRIPTION
.PP
The \fBextfileselectionbox\fR command creates an extended file 
selection box which is slightly different than the fileselectionbox widget.
The differences are mostly cosmetic in that the listboxes are 
within a panedwindow and the entryfields for the filter and selection
have been replaced by comboboxes.  Other than that the interface is
practically the same.

.SH "METHODS"
.PP
The \fBextfileselectionbox\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 extfileselectionbox 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 \fBextfileselectionbox\fR
command.
.TP
\fIpathName \fBchildsite\fR
Returns the child site widget path name.
.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 \fBextfileselectionbox\fR
command.
.TP
\fIpathName \fBfilter\fR
Update the current contents of the extended file selection box based 
on the current filter combobox value.
.TP
\fIpathName \fBget\fR
Returns the current value of the selection combobox widget.
