NAME

       clipboard - Manipulate Tk clipboard

SYNOPSIS

       clipboard option ?arg arg ...?
_________________________________________________________________

DESCRIPTION

       This  command  provides a Tcl interface to the Tk clipboard, which stores data for later retrieval using the selection mechanism.  In order
       to copy data into the clipboard, clipboard clear must be called, followed by a sequence of one or  more	calls  to  clipboard  append.	To
       ensure that the clipboard is updated atomically, all appends should be completed before returning to the event loop.

       The  first  argument  to clipboard determines the format of the rest of the arguments and the behavior of the command.  The following forms
       are currently supported:

       clipboard clear ?-displayof window?
	      Claims ownership of the clipboard on window's display and removes any previous contents.	Window	defaults  to  ``.''.   Returns	an
	      empty string.

       clipboard append ?-displayof window? ?-format format? ?-type type? ?--? data
	      Appends  data to the clipboard on window's display in the form given by type with the representation given by format and claims own-
	      ership of the clipboard on window's display.

	      Type specifies the form in which the selection is to be returned (the desired ``target'' for conversion, in ICCCM terminology),  and
	      should  be  an  atom  name  such as STRING or FILE_NAME; see the Inter-Client Communication Conventions Manual for complete details.
	      Type defaults to STRING.

	      The format argument specifies the representation that should be used to transmit the selection to the requester (the  second  column
	      of  Table 2 of the ICCCM), and defaults to STRING.  If format is STRING, the selection is transmitted as 8-bit ASCII characters.	If
	      format is ATOM, then the data is divided into fields separated by white space; each field is converted to its atom  value,  and  the
	      32-bit  atom  value  is transmitted instead of the atom name.  For any other format,  data is divided into fields separated by white
	      space and each field is converted to a 32-bit integer; an array of integers is transmitted to the selection  requester.	Note  that
	      strings  passed  to  clipboard append are concatenated before conversion, so the caller must take care to ensure appropriate spacing
	      across string boundaries.  All items appended to the clipboard with the same type must have the same format.

	      The format argument is needed only for compatibility with clipboard requesters that don't use Tk.  If the Tk toolkit is  being  used
	      to retrieve the CLIPBOARD selection then the value is converted back to a string at the requesting end, so format is irrelevant.

	      A -- argument may be specified to mark the end of options:  the next argument will always be used as data.  This feature may be con-
	      venient if, for example, data starts with a -.
