java - 向图像添加标签 SWT Java

Question

我正在尝试在图像下添加标签。但按照以下方式执行不会显示任何标签。仅显示图像。

    public void open() {
    Display display = Display.getDefault();
    createContents();
    Label lblNewLabel = new Label(shell, SWT.NONE);
    lblNewLabel.setBounds(40, 21, 217, 178);
    lblNewLabel.setText("New Label");


    Image i = new Image(display, "where the image is");
    lblNewLabel.setImage(i);


    CLabel cLabel = new CLabel(shell, SWT.ARROW_RIGHT);

    cLabel.setImage(i);
    cLabel.setText("SWT CLabel");
    shell.open();
    shell.layout();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) {
            display.sleep();
        }
    }
}


protected void createContents() {
    shell = new Shell();
    shell.setSize(450, 300);
    shell.setText("SWT Application");


}

这样解决:

        Label lblNewLabel_1 = new Label(composite, SWT.BORDER);
        GridData gd_lblNewLabel_1 = new GridData(SWT.CENTER, SWT.CENTER, false, false, 1, 1);
        gd_lblNewLabel_1.widthHint = 193;
        gd_lblNewLabel_1.heightHint = 193;
        lblNewLabel_1.setLayoutData(gd_lblNewLabel_1);
        Image image = new Image(display, "where the image is");
        lblNewLabel_1.setImage(image);
        lblNewLabel_1 = new Label(composite, SWT.BORDER);
        lblNewLabel_1.setText("image label");
