Public Instance Methods
Returns the current background color as device color object, or nil if no background color is set, when no argument is given. Otherwise sets the background color using the color argument and returns self.
See HexaPDF::Content::ColorSpace.device_color_from_specification for information on the allowed arguments.
Returns the AcroForm field object to which this widget annotation belongs.
Since a widget and a field can share the same dictionary object, the returned object is often just the widget re-wrapped in the correct field class.
Returns a MarkerStyle instance representing the marker style of the widget when no argument is given. Otherwise sets the button marker style of the widget and returns self.
This method returns valid information only for check boxes and radio buttons!
When setting a marker style, arguments that are not provided will use the default: a black auto-sized checkmark (i.e. :check for for check boxes) or circle (:circle for radio buttons). This also means that multiple invocations will reset all prior values.
Note: The marker is called “normal caption” in the PDF 2.0 spec and the /CA entry of the associated appearance characteristics dictionary. The marker size and color are set using the /DA key on the widget (although /DA is not defined for widget, this is how Acrobat does it).
