The segments field is  * used to specify text ranges in the line that should be treated as  * separate segments for bidi reordering.  Each segment will be reordered  * and rendered separately. * <p> * The elements in the segments field specify the start offset of  * a segment relative to the start of the line. They must follow * the following rules: * <ul> * <li>first element must be 0 * <li>elements must be in ascending order and must not have duplicates * <li>elements must not exceed the line length * </ul> * In addition, the last element may be set to the end of the line  * but this is not required. * * The segments field may be left null if the entire line should  * be reordered as is. * </p> * A BidiSegmentListener may be used when adjacent segments of  * right-to-left text should not be reordered relative to each other.  * For example, within a Java editor, you may wish multiple  * right-to-left string literals to be reordered differently than the * bidi algorithm specifies.   * * Example: * <pre> * 	stored line = "R1R2R3" + "R4R5R6" *		R1 to R6 are right-to-left characters. The quotation marks * 		are part of the line text. The line is 13 characters long. *  * 	segments = null:  * 		entire line will be reordered and thus the two R2L segments  * 		swapped (as per the bidi algorithm).  *		visual line (rendered on screen) = "R6R5R4" + "R3R2R1" *  * 	segments = [0, 5, 8]	 * 		"R1R2R3" will be reordered, followed by [blank]+[blank] and  * 		"R4R5R6".  *		visual line = "R3R2R1" + "R6R5R4" * </pre> */public class BidiSegmentEvent extends TypedEvent {	/** line start offset */	public int lineOffset;	/** line text */				public String lineText;	/** bidi segments, see above */	public int[] segments;			BidiSegmentEvent(StyledTextEvent e) {	super(e);	lineOffset = e.detail;	lineText = e.text;}}
