DtEditorUndoEdit(3)
CDE
NAME
  DtEditorUndoEdit - undo the last edit made to the text in a DtEditor widget

SYNOPSIS
  #include <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.
