Java 如何在SWT中扩展组件布局？

我创建了一个包含两部分的应用程序：

      1. tree viewer
      2. table viewer + messages

看起来像

                 -------------------------------
                 -   tree    -         table   -   
                 -           -                 -
                 -           - -----------------             
                 -           -                 -
                 -           -   messages      -       
                 -------------------------------

问题是正确的部分（表和消息不像第一部分那样一直延伸到末尾）

看起来像

                  -------------------------------
                 -   tree    -         table   -   
                 -           -  -----------------               -
                 -           -                  -
                                 meesages       -    
                 -           --------------------  
                 -           -              
                 -------------

这是密码

     SashForm sashForm = new SashForm(parent, SWT.HORIZONTAL);
    Composite treeComposite = new Composite(sashForm, SWT.BORDER);
    Composite detailsCompositePart = new Composite(sashForm, SWT.NONE);

    GridLayout detailsGridLayout = new GridLayout();
    detailsGridLayout.numColumns = 1;
    detailsCompositePart.setLayout(detailsGridLayout);

    GridData detailsPartGridData = new GridData(SWT.FILL, SWT.FILL, true, true);
    detailsCompositePart.setLayoutData(detailsPartGridData);

    detailsComposite = new Composite(detailsCompositePart, SWT.BORDER);
    GridLayout detailsSideGridLayout = new GridLayout();
    detailsSideGridLayout.numColumns = 1;
    detailsComposite.setLayout(detailsSideGridLayout);
    GridData detailsGridData = new GridData(SWT.FILL, SWT.FILL, true, true);
    detailsComposite.setLayoutData(detailsGridData);

     messageComposite = new Composite(detailsComposite, SWT.NONE);

     GridLayout messageGridLayout = new GridLayout();
     messageGridLayout.numColumns = 1;
     messageComposite.setLayout(messageGridLayout);
     GridData messageGridData = new GridData(SWT.FILL, SWT.END, true, false);
     messageComposite.setLayoutData(messageGridData);



    labelError = new Label(messageGridData , SWT.NONE);
    GridData data = new GridData(SWT.FILL, SWT.END, true, false);
    data.heightHint = 30;
    labelError.setLayoutData(data);
    //labelError.setText("Message!!!!!!!!!!!!!!"); //$NON-NLS-1$

没有完整的代码，很难判断发生了什么

以下是一些代码，可以帮助您：

public static void main(String[] args)
{
    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setLayout(new GridLayout(1, false));
    shell.setText("StackOverflow");

    Composite horizontal = new Composite(shell, SWT.NONE);
    horizontal.setLayout(new GridLayout(2, false));
    horizontal.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    Composite left = new Composite(horizontal, SWT.BORDER);
    left.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    Composite right = new Composite(horizontal, SWT.NONE);
    GridLayout layout = new GridLayout(1, false);
    layout.marginHeight = 0;
    layout.marginWidth = 0;
    right.setLayout(layout);
    right.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    Composite top = new Composite(right, SWT.BORDER);
    top.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    Composite bottom = new Composite(right, SWT.BORDER);
    bottom.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    shell.pack();
    shell.setSize(600, 400);
    shell.open();

    while (!shell.isDisposed())
    {
        if (!display.readAndDispatch())
        {
            display.sleep();
        }
    }

    display.dispose();
}

看起来像这样：

如果这不是您想要的，请使用更多详细信息/代码更新您的问题。

但我添加了ridata detailsridata=new GridData（）；detailsGridData.horizontalAlignment=SWT.FILL；detailsGridData.grabExcessHorizontalSpace=true；detailsGridData.verticalAlignment=SWT.FILL；detailsGridData.grabExcessVerticalSpace=true；detailsComposite.setLayoutData（detailsGridData）@user1365697更新了我的答案。@user1365697当然，更新了答案。看起来是一样的。嗨，巴兹，我们可以聊一聊吗？我更新了我的代码，通常在右侧屏幕上，拆分为树，消息有两个不同的组合（它们有相同的父项）。问题是，我在版面中看不到任何消息，版面的大小与左侧屏幕的大小不一样。我希望该表将捕获几乎所有屏幕，并且消息只能显示一行
