     DtEditorUndoEdit(3UNIX System V (1 August 1995DtEditorUndoEdit(3)

     NAME
	  DtEditorUndoEdit - undo the last edit made to the text in a
	  DtEditor widget

     SYNOPSIS
	  #include <Dt/Editor.h>

	  Boolean DtEditorUndoEdit(Widget widget);

     DESCRIPTION
	  The DtEditorUndoEdit() function undoes the last change
	  (deletion or insertion) made to the text in a DtEditor
	  widget.  A change consists of either a set of consecutive
	  insertions, or a set of consecutive deletions followed by up
	  to one set of consecutive insertions.	 An insertion is
	  consecutive if there have been no intervening deletions, and
	  it is continuing forward from the same point.	 A deletion is
	  consecutive if there have been no intervening insertions,
	  and its start or end position is coincidental with the last
	  deletion (that is, the deletion is continuing from the same
	  point, either forward or backward).  Undoing an edit once
	  restores the original text.  Undoing an edit twice restores
	  the last change.

	  The widget argument specifies the DtEditor widget ID.

	  For a complete definition of the DtEditor widget and its
	  associated resources, see DtEditor(3).

     RETURN VALUE
	  Upon successful completion, the DtEditorUndoEdit() function
	  returns True; otherwise, if there is no pending undo it
	  returns False.

     SEE ALSO
	  DtEditor(5), DtEditor(3).
