java - 小部件和复合材料不会调整为外壳大小

Question

我的 GUI 遇到了很大的问题，每当屏幕最大化时，小部件和合成似乎不会在屏幕上伸展或排列 - 我尝试使用布局，但它们没有给我正确的结果。我需要它——

您可以简单地使用GridLayoutand的组合GridData：

protected Shell       shell;
public static boolean fullScreen = false;

public static void main(String[] args)
{
    try
    {
        CreateMultipleLineText window = new CreateMultipleLineText();
        window.open();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

public void open()
{
    Display display = Display.getDefault();
    createContents();
    shell.open();
    shell.layout();
    while (!shell.isDisposed())
    {
        if (!display.readAndDispatch())
        {
            display.sleep();
        }
    }
}

protected void createContents()
{
    shell = new Shell();
    shell.setMaximized(true);
    shell.setText("Militia Manager");
    shell.setLayout(new GridLayout(1, false));

    // this creates a composite canvas which houses the start window widgets
    final Composite startComposite = new Composite(shell, SWT.NONE);
    startComposite.setLayout(new GridLayout(1, false));
    startComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    // logo label
    Label logoLabel = new Label(startComposite, SWT.NONE);
    logoLabel.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));
    logoLabel.setText("OUR LOGO GOES HERE");

    // Button for New Game
    Button newGameButton = new Button(startComposite, SWT.PUSH);
    newGameButton.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));
    newGameButton.setText("New Game");

    // Quits
    Button quitButton = new Button(startComposite, SWT.NONE);
    quitButton.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));
    quitButton.setText("Quit");

    // When checked sets boolean
    final Button fullScreenCheckBox = new Button(startComposite, SWT.CHECK);
    fullScreenCheckBox.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, true, true));
    fullScreenCheckBox.setText("Full Screen Mode");
}

看起来像这样：
