Examples of java.awt.font.LineBreakMeasurer.nextLayout()

java.awt.font.LineBreakMeasurer.nextLayout()
Returns the next layout, and updates the current position. @param wrappingWidth the maximum visible advance permitted forthe text in the next layout @return a TextLayout, beginning at the currentposition, which represents the next line fitting within wrappingWidth
