textArea growByContent在图层布局中不起作用

我使用图层布局将 Headers 即textArea保留在按钮图像的顶部 . 但我无法增长textArea的大小 . 此外，textArea上的填充和边距也不起作用 .

Image btnIcon = URLImage.createToStorage(placeholder, "homeIcon" + imageUrl, allUrl.globalHomeImageUrl + imageUrl, URLImage.RESIZE_SCALE);
            int width = placeholder.getWidth();
            int height = placeholder.getHeight();
            homeButton.setPreferredSize(new Dimension(width, height));
            homeButton.getAllStyles().setBgImage(btnIcon);

            TextArea buttonTitle = new TextArea(title);
            buttonTitle.setRows(1);
            buttonTitle.setUIID("smallLabel");
            buttonTitle.getAllStyles().setPadding(0, 0, 0, 0);
            buttonTitle.getAllStyles().setMargin(0, 4, 0, 4);
            buttonTitle.setPreferredW(screenWidth / 3 - 30);
            buttonTitle.setEditable(false);
            buttonTitle.setGrowByContent(true);
            buttonTitle.setIsScrollVisible(false);
            buttonTitle.setGrowLimit(2);
            Container container1 = new Container();
            container1.setUIID("buttonTitleContainer");
            container1.getAllStyles().setMargin(0, 5, 0, 0);
            container1.getAllStyles().setBgTransparency(0);
            container1.add(LayeredLayout.encloseIn(homeButton,     FlowLayout.encloseRightBottom(buttonTitle)));
            middleContainer.addComponent(BorderLayout.CENTER, container1);

如何根据需要增长textArea行并设置textarea的填充边距 .

更新：我评论了setPreferredW（）并添加了calcPreferredSize（）来设置维度，但我如何动态设置高度？

TextArea buttonTitle = new TextArea(title){

                        @Override
                        protected Dimension calcPreferredSize() {
                            Dimension d = new Dimension(screenWidth/3-10, 40);
                            return d; //To change body of generated methods, choose Tools | Templates.
                        }

                    };
                    buttonTitle.setUIID("smallLabel");
                    buttonTitle.getAllStyles().setAlignment(Label.LEFT);
                    buttonTitle.setRows(1);
                    buttonTitle.getAllStyles().setPadding(0, 0, 0, 0);
                    buttonTitle.getAllStyles().setMargin(0, 0, 0, 4);
//                    buttonTitle.setPreferredW(screenWidth / 3 - 30);
                    buttonTitle.setEditable(false);
                    buttonTitle.setGrowByContent(true);
                    buttonTitle.setIsScrollVisible(false);
                    buttonTitle.setGrowLimit(2);
                    buttonTitle.setScrollVisible(false);

设计有点像下面：

当前屏幕截图：正如您所看到的，只显示了一个单词，textArea总是只有一行并且不会增长
