## Detailed Description

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.

## Member Enumeration Documentation

enum pdftron::PDF::Annots::Widget::HighlightingMode

This enum specifies the Highlighting mode of the widget annotation

Enumerator
e_none | No highlighting.
e_invert | Invert the contents of the annotation rectangle.
e_outline | Invert the annotation's border.
e_push | Display the annotation's down appearance, if any. If no down appearance is defined, the contents of the annotation rectangle shall be offset to appear as if it were being pushed below the surface of the page.
e_toggle | Same as e_push (which is preferred).

Definition at line 66 of file Widget.h.

enum pdftron::PDF::Annots::Widget::IconCaptionRelation

An enumeration indicating where to position the text of the annotation's caption relative to its icon.

e_NoIcon - No icon; caption only e_NoCaption - No caption; icon only e_CBelowI - Caption below the icon e_CAboveI - Caption above the icon e_CRightILeft - Caption to the right of the icon e_CLeftIRight - Caption to the left of the icon e_COverlayI - Caption overlaid directly on the icon Default value: e_NoIcon.

enum pdftron::PDF::Annots::Widget::ScaleCondition

Note
  The functionality documented below is part of the Icon Fit dictionary. This dictionary specifies how to display the button's icon within the annotation rectangle. If present, the icon fit dictionary shall apply to all of the annotation's icons (normal, rollover, and alternate). This enum represents the circumstances under which the icon shall be scaled inside the annotation rectangle .

Enumerator
e_Always | Always scale.
e_WhenBigger | Scale only when the icon is bigger than the annotation rectangle.
e_WhenSmaller | Scale only when the icon is smaller than the annotation rectangle.
e_Never | Never scale.

Definition at line 366 of file Widget.h.

enum pdftron::PDF::Annots::Widget::ScaleType

This enum represents the scale type of the annotation.

e_Anamorphic - Scale the icon to fill the annotation rectangle exactly, without regard to its original aspect ratio (ratio of width to height). e_Proportional - Scale the icon to fit the width or height of the annotation rectangle while maintaining the icon's original aspect ratio. If the required horizontal and vertical scaling factors are different, use the smaller of the two, centering the icon within the annotation rectangle in the other dimension. Default value: e_Proportional.

Enumerator
e_Anamorphic |
e_Proportional |
