public class TextFields
extends java.lang.Object

A TextFields is an adjunct to a JEditorPane. It delimits sections of the text that are editable and highlighted. There is also provision for adding labels with arrows to the segments. For each field, the html text of the document contains <span field="fieldname">intial value</span> Additional optional attributes label="labelname" Text to display in the label, if any. Defaults to field name. writable="false" If value is (exactly) "false" the field will not be writable hidden="true" If true the field is invisible, but takes up space. arrow-width="2.0" Width of arrow from label to field. arrow-color="green" Color of arrow from label to field Valid values are one of the java color names or #rrggbb, where r, g, b are hexadecimal digits The writable="false" attribute should be omitted for input fields highlighter is called once or twice a second while window has focus at least should not redraw if no change but seems to be blanked out frequently and need redrawn. sigh
