DwtStartCopyFromClipboard(3Dwt) 										   DwtStartCopyFromClipboard(3Dwt)

Name
       DwtStartCopyFromClipboard - Indicates that the application is ready to start copying data from the clipboard and locks the clipboard.

Syntax
       int DwtStartCopyFromClipboard(display, window, time)
	    Display *display;
	    Window window;
	    Time time;

Arguments
       display	 Specifies  a pointer to the Display structure that was returned in a previous call to XOpenDisplay.  For information on XOpenDis-
		 play and the Display structure, see the Guide to the Xlib Library: C Language Binding.

       window	 Specifies the window ID that relates the application window to the clipboard.	The same application instance should pass the same
		 window ID to each clipboard function that it calls.

       time	 Specifies the timestamping of the event that triggered the copy.

Description
       The  DwtStartCopyFromClipboard  function  notifies the cut and paste functions that the application is ready to start copying data from the
       clipboard.  DwtStartCopyFromClipboard locks the clipboard and remains locked until you call DwtEndCopyFromClipboard.

       After calling DwtStartCopyFromClipboard, an application can make multiple calls to DwtCopyFromClipboard requesting data in one  or  several
       formats.  You specify the format by setting the format_name argument to DwtCopyFromClipboard.  Each call to DwtCopyFromClipboard in a spec-
       ified format results in data being incrementally copied from the clipboard until all data with the specified format has been copied.   When
       all  data  in a specified format has been successfully copied, DwtCopyFromClipboard returns ClipboardSuccess.  When more data remains to be
       copied in the specified format, DwtCopyFromClipboard returns ClipboardTruncate.	An application can copy data in as many formats as desired
       before calling DwtEndCopyFromClipboard.

       It  is  recommended  that any calls to inquire routines needed by the application be made between the call to DwtStartCopyFromClipboard and
       the call to DwtEndCopyFromClipboard.  That way, the application does not need to call DwtClipboardLock and DwtClipboardUnlock.

       To perform cut and paste operations between your application and an application using the ICCCM clipboard selection mechanism, you must use
       DwtStartCopyToClipboard	and  provide  a  timestamping  value for time, not a CurrentTime value.  Use of the value CurrentTime for time may
       cause the ICCCM interface to fail.

       Applications do not need to use DwtStartCopyFromClipboard and DwtEndCopyFromClipboard, in which case DwtCopyFromClipboard  works  as  docu-
       mented.	However, using these two functions allows incremental copying from the clipboard and ensures ICCCM compatibility.

Return Values
       This function returns one of these status return constants:

       ClipboardSuccess   The  function is success-
			  ful.
       ClipboardLocked	  The	 function    failed
			  because the clipboard was
			  locked by another  appli-
			  cation.   The application
			  can continue to call	the
			  function  with  the  same
			  parameters   until	the
			  clipboard   is  unlocked.
			  Optionally, the  applica-
			  tion	can ask if the user
			  wants to keep  trying  or
			  to  give up on the opera-
			  tion.

Name
       DwtStartCopyToClipboard - Sets up storage and data structures to receive clipboard data.

Syntax
       int DwtStartCopyToClipboard(display, window, clip_label,
				  time, widget, callback, item_id)
	    Display *display;
	    Window window;
	    DwtCompString clip_label;
	    Time time;
	    Widget widget;
	    VoidProc callback;
	    long *item_id;

Arguments
       display	 Specifies  a pointer to the Display structure that was returned in a previous call to XOpenDisplay.  For information on XOpenDis-
		 play and the Display structure, see the Guide to the Xlib Library: C Language Binding.

       window	 Specifies the window ID that relates the application window to the clipboard.	The same application instance should pass the same
		 window ID to each clipboard function that it calls.

       clip_label
		 Specifies  the  label	to  be	associated with the data item.	This argument is used to identify the data item, for example, in a
		 clipboard viewer.  An example of a label is the name of the application that places the data in the clipboard.

       time	 Specifies the timestamping of the event that triggered the copy.

       widget	 Specifies the ID of the widget that will receive messages requesting data previously passed  by  name.   This	argument  must	be
		 present in order to pass data by name.  Any valid widget ID in your application can be used.  All message handling is done by the
		 cut and paste functions.

       callback  Specifies the address of the callback function that is called when the clipboard needs data that was originally passed  by  name.
		 This  is  also  the  callback to receive the DELETE message for items that were originally passed by name.  This argument must be
		 present in order to pass data by name.

       item_id	 Specifies the number assigned to this data item.  The application uses this number in calls to DwtCopyToClipboard,  DwtEndCopyTo-
		 Clipboard, and DwtCancelCopyToClipboard.

Description
       The  DwtStartCopyToClipboard  function sets up storage and data structures to receive clipboard data.  An application calls DwtStartCopyTo-
       Clipboard during a cut or copy operation.  The data item that these structures receive through calls to DwtCopyToClipboard then becomes the
       next item to be pasted (the next-paste item) in the clipboard after the call to DwtEndCopyToClipboard.

       DwtStartCopyToClipboard is like DwtBeginCopyToClipboard except that it has the time argument to support the ICCCM clipboard selection mech-
       anism.  To perform cut and paste operations between your application and an application using the ICCCM clipboard selection mechanism,  you
       must use DwtStartCopyToClipboard and provide a timestamping value for time, not a CurrentTime value.  Use of the value CurrentTime for time
       may cause the ICCCM interface to fail.

       The window and callback arguments must be present in order to pass data by name.

       The callback format is as follows:

       function name(widget, data_id, private_id, reason)
	    Widget *widget;
	    int *data_id;
	    int *private_id;
	    int *reason;

       widget	 Specifies the ID of the widget passed to DwtStartCopyToClipboard.

       data_id	 Specifies the identifying number returned by DwtCopyToClipboard, which identifies the pass-by-name data.

       private_id
		 Specifies the private information passed to DwtCopyToClipboard.

       reason	 Specifies the reason, which is either DwtCRClipboardDataDelete or DwtCRClipboardDataRequest.

Return Values
       This function returns one of these status return constants:

       ClipboardSuccess   The function is  success-
			  ful.
       ClipboardLocked	  The	 function    failed
			  because the clipboard was
			  locked  by another appli-
			  cation.  The	application
			  can  continue to call the
			  function  with  the  same
			  parameters	until	the
			  clipboard  is   unlocked.
			  Optionally,  the applica-
			  tion can ask if the  user
			  wants  to  keep trying or
			  to give up on the  opera-
			  tion.
