NAME
       Wharf - the AfterStep application "dock"	module

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

DESCRIPTION
       The Wharf module	is a free-floating application loader that can execute
       programs, "Swallow" running programs, and contain "Folders" of more ap-
       plications, 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	after-
       step is used as the window manager.

COPYRIGHTS
       The  Wharf  module is copyright 1995 and	1996 by	a variety of contribu-
       tors.  They are,	in alphabetical	order, Beat Christen, Frank Fejes, Al-
       fredo 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

       No guarantees or	warranties or anything are provided or implied in  any
       way  whatsoever.	 Use  this program at your own risk. Permission	to use
       this program for	any purpose is given, as long as the copyright is kept
       intact.

INITIALIZATION
       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 dif-
       ferent configuration  than  Wharf,  simply  by  changing	 the  keywords
       Wharf???	to Pier???. This way multiple button-bars can be used.

INVOCATION
       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 di-
       rectory	specified in the ModulePath configuration option to attempt to
       locate Wharf.

CONFIGURATION OPTIONS
       The following options can be placed in the .steprc file

       *WharfAnimate
	      If specified, the	opening	and closing of Folders	will  be  ani-
	      mated, rather than simply	drawn in one frame.

       *WharfAnimateMain
	      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 un-
	      specified,  the number of	columns	will be	set to 1.  If the col-
	      umns are set to a	number greater than 1 then there will be  that
	      number of	columns	with enough rows to satisfy the	requested num-
	      ber of buttons.

       *WharfForceSize
	      If specified, will force pixmaps larger than 64x64  to  the  de-
	      fault size.  Pixmaps smaller than	64x64 are not supported.

       *WharfFullPush
	      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  man-
	      ner.   The geometry is a standard	X11 window geometry specifica-
	      tion.  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.

       *WharfNoBorder
	      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 but-
	      tons.  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	 acti-
	      vate  (folders will be discussed below), as described in the af-
	      terstep 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 pro-
	      vided.  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 spe-
	      cial option called MaxSwallow.  MaxSwallow will allow the	appli-
	      cation to	draw itself larger than	the 48x48 boundary.  It	is in-
	      voked 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 defini-
	      tion 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  perpendicu-
	      lar  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 fold-
	      ers are Swallowed	applications and more folders.

DRAG AND DROP
       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
       filename.
