DESCRIPTION

       The Panedwindow method creates a new window (given by the $panedwindow argument) and makes
       it into a Panedwindow widget.  Additional options, described above, may be specified on
       the command line or in the option database to configure aspects of the Panedwindow such as
       its default background color and relief.

       A Panedwindow widget contains any number of panes, arranged horizontally or vertically,
       according to the value of the -orient option.  Each pane contains one widget, and each
       pair of panes is separated by a moveable (via mouse movements) sash.  Moving a sash causes
       the widgets on either side of the sash to be resized.

WIDGET METHODS

       The Panedwindow method may be used to invoke various operations on the widget.  It has the
       following general form:

        $widget->method(?arg arg ...?);

       The following commands are possible for Panedwindow widgets:

       $widget->add(?window ...? ?option value ...?);
           Add one or more windows to the Panedwindow, each in a separate pane.  The arguments
           consist of the names of one or more windows followed by pairs of arguments that
           specify how to manage the windows.  Option may have any of the values accepted by the
           configure subcommand.

       $widget->cget(option);
           Returns the current value of the configuration option given by option.  Option may
           have any of the values accepted by the Panedwindow command.

       $widget->configure(?option?, ?value, option, value, ...?);
           Query or modify the configuration options of the widget.  If no option is specified,
           returns a list describing all of the available options for $widget (see Tk::configure
           for information on the format of this list).  If option is specified with no value,
           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 option is
           specified).  If one or more option-value 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. Option may have any of the values accepted by the
           Panedwindow command.

       $widget->forget(?window ...?);
           Remove the pane containing $widget from the Panedwindow.  All geometry management
           options for $widget will be forgotten.

       $widget->identify(x, y);
           Identify the Panedwindow component underneath the point given by x and y, in window
           coordinates.  If the point is over a sash or a sash handle, the result is a two
           element list containing the index of the sash or handle, and a word indicating whether
           it is over a sash or a handle, such as [0, 'sash'] or [2, 'handle'].  If the point is
           over any other part of the Panedwindow, the result is an empty list.

       $widget->proxy(?args?);
           This command is used to query and change the position of the sash proxy, used for
           rubberband-style pane resizing. It can take any of the following forms:

           $widget->proxyCoord;
               Return a list containing the x and y coordinates of the most recent proxy
               location.

           $widget->proxyForget;
               Remove the proxy from the display.

           $widget->proxyPlace(x, y);
               Place the proxy at the given x and y coordinates.

       $widget->sash(?args?);
           This command is used to query and change the position of sashes in the Panedwindow.
           It can take any of the following forms:

           $widget->sashCoord(index);
               Return the current x and y coordinate pair for the sash given by index.  Index
               must be an integer between 0 and 1 less than the number of panes in the
               Panedwindow.  The coordinates given are those of the top left corner of the region
               containing the sash.  $widget->sashDragto(index, x, y) This command computes the
               difference between the given coordinates and the coordinates given to the last
               sash coord command for the given sash.  It then moves that sash the computed
               difference.  The return value is the empty string.

           $widget->sashMark(index, x, y);
               Records x and y for the sash given by index; used in conjunction with later dragto
               commands to move the sash.

           $widget->sashPlace(index, x, y);
               Place the sash given by index at the given coordinates.

       $widget $widget->panecget(option);
           Query a management option for $widget.  Option may be any value allowed by the
           paneconfigure subcommand.

       $widget $widget->paneconfigure(?option? ?value option value ...?);
           Query or modify the management options for $widget.  If no option is specified,
           returns a list describing all of the available options for $widget (see Tk::configure
           for information on the format of this list).  If option is specified with no value,
           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 option is
           specified).  If one or more option-value 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.  The following options are supported:

           -after => $widget
               Insert the window after the window specified.  $widget should be the name of a
               window already managed by $widget.

           -before => $widget
               Insert the window before the window specified.  $widget should be the name of a
               window already managed by $widget.

           -height => size
               Specify a height for the window.  The height will be the outer dimension of the
               window including its border, if any.  If size is an empty string, or if -height is
               not specified, then the height requested internally by the window will be used
               initially; the height may later be adjusted by the movement of sashes in the
               Panedwindow.  Size may be any value accepted by Tk_GetPixels.

           -minsize => n
               Specifies that the size of the window cannot be made less than n.  This constraint
               only affects the size of the widget in the paned dimension -- the x dimension for
               horizontal Panedwindows, the y dimension for vertical Panedwindows.  May be any
               value accepted by Tk_GetPixels.

           -padx => n
               Specifies a non-negative value indicating how much extra space to leave on each
               side of the window in the X-direction.  The value may have any of the forms
               accepted by Tk_GetPixels.

           -pady => n
               Specifies a non-negative value indicating how much extra space to leave on each
               side of the window in the Y-direction.  The value may have any of the forms
               accepted by Tk_GetPixels.

           -sticky => style
               If a window's pane is larger than the requested dimensions of the window, this
               option may be used to position (or stretch) the window within its pane.  Style  is
               a string that contains zero or more of the characters n, s, e or w.  The string
               can optionally contains spaces or commas, but they are ignored.  Each letter
               refers to a side (north, south, east, or west) that the window will "stick" to.
               If both n and s (or e and w) are specified, the window will be stretched to fill
               the entire height (or width) of its cavity.

           -width => size
               Specify a width for the window.  The width will be the outer dimension of the
               window including its border, if any.  If size is an empty string, or if -width is
               not specified, then the width requested internally by the window will be used
               initially; the width may later be adjusted by the movement of sashes in the
               Panedwindow.  Size may be any value accepted by Tk_GetPixels.

       $widget->panes;
           Returns an ordered list of the widgets managed by $widget.

RESIZING PANES

       A pane is resized by grabbing the sash (or sash handle if present) and dragging with the
       mouse.  This is accomplished via mouse motion bindings on the widget.  When a sash is
       moved, the sizes of the panes on each side of the sash, and thus the widgets in those
       panes, are adjusted.

       When a pane is resized from outside (eg, it is packed to expand and fill, and the
       containing toplevel is resized), space is added to the final (rightmost or bottommost)
       pane in the window.
