NAME
       Tk::clipboard - Manipulate Tk clipboard

SYNOPSIS
       $widget->clipboardOption?(args)?

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

       The following methods are currently supported:

       $widget->clipboardClear
	   Claims ownership of the clipboard on $widget's display and removes any previous
	   contents.   Returns an empty string.

       $widget->clipboardAppend(?-format=>format?,?-type=>type?,?--?,data)
	   Appends data to the clipboard on $widget's display in the form given by type with the
	   representation given by format and claims ownership of the clipboard on $widget'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.  See the Tk::Selection documentation for explanation of what
	       happens if format is not STRING.  Note that arguments passed to clipboardAppend
	       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.

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

       $widget->clipboardGet( ?-type? );
	   Retrieve data from the clipboard on	widget's  display.  -type specifies the form in
	   which the data is to be returned and should be an atom  name  such  as  STRING  or
	   FILE_NAME.  Type defaults to STRING.  This command is equivalent to "SelectionGet(
	   -selection => 'CLIPBOARD' )".
