DESCRIPTION

       The  panedwindow  command  creates  a new window (given by the pathName
       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.  The panedwindow command returns the path
       name of the new window.

       A panedwindow widget contains any number of  panes,  arranged  horizon-
       tally  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 COMMAND

       The panedwindow command creates a new Tcl command  whose  name  is  the
       same as the path name of the panedwindow's window.  This command may be
       used to invoke various operations on the widget.  It has the  following
       general form:
              pathName option ?arg arg ...?
       PathName is the name of the command, which is the same as the panedwin-
       dow widget's path name.  Option and the args determine the exact behav-
       ior  of the command.  The following commands are possible for panedwin-
       dow widgets:

       pathName add window ?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 con-
              figure subcommand.

       pathName 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.

       pathName 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 avail-
              able options for pathName (see Tk_ConfigureInfo 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.

       pathName forget window ?window ...?
              Remove the pane containing window  from  the  panedwindow.   All
              geometry management options for window will be forgotten.

       pathName 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.

       pathName 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:

              pathName proxy coord
                     Return  a  list containing the x and y coordinates of the
                     most recent proxy location.

              pathName proxy forget
                     Remove the proxy from the display.

              pathName proxy place x y
                     Place the proxy at the given x and y coordinates.

       pathName 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:

              pathName sash coord 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.

              pathName sash dragto index x y
                     This  command  computes  the difference between the given
                     coordinates and the coordinates given to  the  last  sash
                     mark command for the given sash.  It then moves that sash
                     the computed difference.  The return value is  the  empty
                     string.

              pathName sash mark index x y
                     Records x and y for the sash given by index; used in con-
                     junction with later sash  dragto  commands  to  move  the
                     sash.

              pathName sash place index x y
                     Place the sash given by index at the given coordinates.

       pathName panecget window option
              Query  a  management option for window.  Option may be any value
              allowed by the paneconfigure subcommand.

       pathName paneconfigure window ?option? ?value option value ...?
              Query or modify the management options for window.  If no option
              is  specified,  returns  a  list describing all of the available
              options for pathName (see Tk_ConfigureInfo  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 window
                     Insert the window after  the  window  specified.   window
                     should  be  the name of a window already managed by path-
                     Name.

              -before window
                     Insert the window before the  window  specified.   window
                     should  be  the name of a window already managed by path-
                     Name.

              -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 hor-
                     izontal panedwindows, the y dimension for vertical paned-
                     windows.  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-direc-
                     tion.  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-direc-
                     tion.   The  value  may have any of the forms accepted by
                     Tk_GetPixels.

              -sticky style
                     If a window's pane is larger than  the  requested  dimen-
                     sions  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.

       pathName panes
              Returns an ordered list of the widgets managed by pathName.


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  bind-
       ings  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 (e.g. 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.
