.SH DESCRIPTION
.PP
The \fBscrolledframe\fR combines the functionallity of scrolling with that 
of a typical frame widget to implement a clipable viewing area whose visible 
region may be modified with the scroll bars. This enables the contruction 
of visually larger areas than which could normally be displayed, containing 
a heterogenous mix of other widgets. Options exist which allow full control
over which scrollbars are displayed and the method, i.e. statically or
dynamically. The frame itself may be accessed by the \fBchildsite\fR
method and then filled with other widget combinations.

.SH "METHODS"
.PP
The \fBscrolledframe\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 scrolledframe 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 \fBscrolledframe\fR
command.
.TP
\fIpathName \fBchildsite\fR
Return the path name of the child site.
.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 \fBscrolledframe\fR
command.
.TP
\fIpathName \fBjustify \fIdirection\fR
Justifies the frame contents via the scroll bars in one of four directions:
\fBleft\fR, \fBright\fR, \fBtop\fR, or \fBbottom\fR.
