Class Widget

Interactive forms use widget annotations (PDF 1.2) to represent the appearance of fields and to manage user interactions. As a convenience, when a field has only a single associated widget annotation, the contents of the field dictionary and the annotation dictionary may be merged into a single dictionary containing entries that pertain to both a field and an annotation. NOTE This presents no ambiguity, since the contents of the two kinds of dictionaries do not conflict.
