<H2>DESCRIPTION</H2><PRE>
The <STRONG>scrolledframe</STRONG> 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 <STRONG>childsite</STRONG> method and then filled with
other widget combinations.
</PRE>
<H2>METHODS</H2><PRE>
The <STRONG>scrolledframe</STRONG> command creates a new Tcl command whose
name is <EM>pathName</EM>. This command may be used to invoke vari-
ous operations on the widget. It has the following general
form:
<EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
<EM>Option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
mand. The following commands are possible for scrolledframe
widgets:

<STRONG>xview</STRONG> <STRONG>yview</STRONG>
See the "canvas" manual entry for details on the associated
methods.

<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
<EM>pathName</EM> <STRONG>cget</STRONG> <EM>option</EM>
Returns the current value of the configuration option
given by <EM>option</EM>. <EM>Option</EM> may have any of the values
accepted by the <STRONG>scrolledframe</STRONG> command.
<EM>pathName</EM> <STRONG>childsite</STRONG>
Return the path name of the child site.
<EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
Query or modify the configuration options of the
widget. If no <EM>option</EM> is specified, returns a list
describing all of the available options for <EM>pathName</EM>
(see <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
this list). If <EM>option</EM> is specified with no <EM>value</EM>, then
the command returns a list describing the one named
option (this list will be identical to the correspond-
ing sublist of the value returned if no <EM>option</EM> is
specified). If one or more <EM>option</EM> - <EM>value</EM> 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. <EM>Option</EM> may have any
of the values accepted by the <STRONG>scrolledframe</STRONG> command.
<EM>pathName</EM> <STRONG>justify</STRONG> <EM>direction</EM>
Justifies the frame contents via the scroll bars in one
of four directions: <STRONG>left</STRONG>, <STRONG>right</STRONG>, <STRONG>top</STRONG>, or <STRONG>bottom</STRONG>.
