Wharf(1.0)                                                            Wharf(1.0)

       Wharf - the AfterStep application "dock" module

       Wharf is spawned by afterstep, so no command line invocation will work.

       The Wharf module is a free-floating application loader that can execute
       programs, "Swallow" running programs, and contain "Folders" of more
       applications, among other things.  The user can press the first button at
       any time to trigger invocation of one of these functions, or the user can
       press button two in order to cause the entire Wharf to withdraw to the
       nearest corner in an iconized state.  Wharf only works when afterstep is
       used as the window manager.

       The Wharf module is copyright 1995 and 1996 by a variety of contributors.
       They are, in alphabetical order, Beat Christen, Frank Fejes, Alfredo
       Kenji Kojima, Dan Weeks, and Bo Yang

       The GoodStuff program, and the concept for interfacing this module to the
       Window Manager, are all original work by Robert Nation

       During initialization, Wharf will search for a configuration file which
       describes the button panel geometry, color, icons, and actions. The
       format of this file will be described later. The configuration file will
       be the one which afterstep used during its initialization.

       If the Wharf executable is linked to another name, ie ln -s Wharf Pier,
       then another module called Pier can be started, with a completely
       different configuration than Wharf, simply by changing the keywords
       Wharf??? to Pier???. This way multiple button-bars can be used.

       Wharf can be invoked by inserting the line 'Module Wharf' in the .steprc
       file. This can be placed on a line by itself, if Wharf is to be spawned
       during AfterStep's initialization, or can be bound to a menu or mouse
       button or keystroke to invoke it later. AfterStep will search directory
       specified in the ModulePath configuration option to attempt to locate

       The following options can be placed in the .steprc file

              If specified, the opening and closing of Folders will be animated,
              rather than simply drawn in one frame.

              Designates that full-length Wharf windraws will be animated.

       *WharfBgColor color
              If *WharfTextureType 0 is specified, Wharf's buttons will be
              filled with color.

       *WharfColumns columns
              Specifies the number of columns of buttons to be created. If
              unspecified, the number of columns will be set to 1.  If the
              columns are set to a number greater than 1 then there will be that
              number of columns with enough rows to satisfy the requested number
              of buttons.

              If specified, will force pixmaps larger than 64x64 to the default
              size.  Pixmaps smaller than 64x64 are not supported.

              If specified, the entire Wharf button background will be moved
              down and to the right when pushed.  Especially useful with
              *WharfNoBorder textures.

       *WharfGeometry geometry
              Specifies the Wharf window location and/or size. If the size is
              not specified, Wharf will auto-size itself in a reasonable manner.
              The geometry is a standard X11 window geometry specification.
              This option is pre-set in the NEXTSTEP(tm) style section for a
              consistent look and feel with NEXTSTEP(tm).  Secondary Wharf
              invocations from links may have their own geometry.

       *WharfMaxColors number
              Specifies the maximum number of colors to use on a gradient fill.

              Denotes that beveled borders should not be drawn around the Wharf
              button.  Useful with textures that include their own bevels.

       *WharfPixmap pixmap
              Sets the pixmap file to be used as Wharf's button.  To be used
              with *WharfTextureType 128.

       *WharfTextureColor from to
              When used with a *WharfTextureType of 1 to 5, designates the ends
              of the gradient range to be used on Wharf's buttons.

       *WharfTextureType  type
              Specifies the type of gradient fill to be used on Wharf's buttons.
              Valid values are:
              0 - No texture - use WharfBgColor to set the desired color
              1 - Gradient from upper-left to lower right
              2 - Horizontal one way gradient from top to bottom
              3 - Horizontal cylindrical gradient from top/bottom to center
              4 - Vertical one way gradient from left to right
              5 - Vertical cylindrical gradient from left/right to center
              128 - User specified pixmap
              The default is the builtin Wharf texture pixmap.

       *Wharf label icon command
              Specifies a window manager built-in command or folder to activate
              (folders will be discussed below), as described in the afterstep
              man page, which should be executed when a button is pressed. The
              label field is an internal item that is still around from the
              GoodStuff module.  The icon field specifies an X11 bitmap file,
              XPM color icon file, or a comma-delimited set of pixmaps
              containing the icon(s) to display on the button. Wharf will search
              through the path specified in the afterstep IconPath or PixmapPath
              configuration items to find the icon file.

              NOTE: Icons must have one transparent pixel or the definition of a
              transparent color in order to be valid.

              If command is an afterstep Exec command, then the button will
              appear pushed in until the mouse button is released.

              A single extension to the afterstep built-in command set is
              provided.  A command of the form:

              *Wharf junk clock.xpm Swallow "Clock" asclock -shape -12 &

              will cause Wharf to spawn an asclock process, and capture the
              first window whose name or resource is "Clock", and display it in
              the button-bar. This is handy for applications like xclock, xbiff,
              xload, asclock, and asmail. Modules can be swallowed by specifying
              SwallowModule instead of just "swallow" NOTE: if you use xclock
              for this application, you will want to specify xclock -padding 0.

              For certain applications that overrun the 48 pixel by 48 pixel
              boundary of Wharf icons and Swallowed programs there is a special
              option called MaxSwallow.  MaxSwallow will allow the application
              to draw itself larger than the 48x48 boundary.  It is invoked the
              same way Swallow is.

              To create folder "slide-outs" in Wharf the following format must
              be used:

              *Wharf files Folders.xpm Folder
              *Wharf xftp 3DRings.xpm  Exec "" xftp &
              *Wharf xdir FolderDeposit.xpm Exec "" xdir &
              *Wharf moxfm FilingCabinet.xpm Exec "" moxfm &
              *Wharf ~Folders

              The first line of this set tells Wharf that this button definition
              will be a folder.  All of the button definitions between the
              Folder and the line with the definition of *Wharf ~Folders will
              appear on the "files" folder when it is exposed.  To expose the
              "files" folder simply click on the Wharf button with the
              Folders.xpm icon showing.  A button bar will appear perpendicular
              to your Wharf bar and toward the center of the screen.  On this
              smaller bar will be the three icons that were configured between
              the Folder and ~Folder parts of the Wharf configuration.  As many
              folder buttons may be configured as is room on your screen.  The
              only items that may not be configured within folders are Swallowed
              applications and more folders.

       Wharf supports the OffiX Drag and Drop standard.  In order to have Drag
       and Drop enabled on a particular button, the following syntax must be
       adhered to:

       *Wharf    nil      nil        DropExec "program" program %s
       *Wharf    program  iconname   Exec "program" program

       The button will call program when pushed.  If a file is dragged onto into
       it, program will be called with %s being replaced by the dropped
