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

      // instancia um line breaker para o texto formatado
      LineBreakMeasurer quebrador = new LineBreakMeasurer(str.getIterator(), 
          gr.getFontRenderContext());    
    
      // cria um TextLayout para armazenar cada linha 'quebrada'
      TextLayout linha = quebrador.nextLayout(larguraTexto);
      while (linha != null) {


        // posiciona o texto
        posY += linha.getAscent();
