Java 选项卡项的滚动条

我在Tabfolder Properties中有一个组，其中放置了一组控件…现在我需要用于放置控件的特定TabItem的滚动条

尝试使用scrollableComposite，但不起作用…我需要如何改进

protected void setControls(Composite parent)
{


    ScrolledComposite s1 = new ScrolledComposite(parent,SWT.V_SCROLL  |SWT.H_SCROLL);
    s1.setExpandHorizontal(true);
        s1.setExpandVertical(true);     


    OptionGroup = new Group(s1, SWT.None);
    OptionGroup.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 2, 1));
    OptionGroup.setLayout(new GridLayout());

    final GridLayout gl_fileOptionGroup1 = new GridLayout();
    gl_fileOptionGroup1.numColumns = 2;
    OptionGroup.setLayout(gl_fileOptionGroup1);
                                          ::::

试一试

s1.setSize(s1.computeSize(SWT.DEFAULT, SWT.DEFAULT));
