Question

如何将ScrollComposite放在SWT中的另一个ScrollComposite中。我用两个scrollcomposite。第一个ScrollComposite包含多个ScrollComposite。每个儿童综合大小相等。因此，如果子ScrollComposite包含长度大于固定大小的小部件，则它滚动（每个子ScrollComposite根据包含小部件滚动），而父scrollComposite是子复合的滚动超过它的长度。

//这是我的代码

      final Composite container = new Composite(parent, SWT.NONE);

                    container.setLayout(new FillLayout(SWT.VERTICAL));
                    container.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
 //First Scroll Composite
                    final ScrolledComposite scrolledComposite = new ScrolledComposite(container, SWT.H_SCROLL | SWT.V_SCROLL | SWT.BORDER);

                    scrolledComposite.setExpandHorizontal(true);
                    scrolledComposite.setExpandVertical(true);

                    cmpNotificationBody = new Composite(scrolledComposite, SWT.NONE);
                    cmpNotificationBody.setLayout(new FillLayout(SWT.VERTICAL));
 //Second Scroll Composite
        final ScrolledComposite scrolledComposite2 = new ScrolledComposite(cmpNotificationBody, SWT.H_SCROLL | SWT.V_SCROLL | SWT.BORDER);

                    scrolledComposite2.setExpandHorizontal(true);
                    scrolledComposite2.setExpandVertical(true);
     cmpNotificationBody2 = new Composite(scrolledComposite2, SWT.NONE);

    //do  child GUI
    //Make Scroll Composite Scrollable
    scrolledComposite2.setContent(cmpNotificationBody2);
            scrolledComposite2.setMinSize(
                    cmpNotificationBody2.computeSize(SWT.DEFAULT, SWT.DEFAULT));
            cmpNotificationBody2.layout();

    scrolledComposite.setContent(cmpNotificationBody);
          scrolledComposite.setMinSize(
                    cmpNotificationBody.computeSize(1,1);
            cmpNotificationBody.layout();

你应该试试这个

final Composite container = new Composite(parent, SWT.NONE);
container.setLayout(new FillLayout(SWT.VERTICAL));
container.setLayoutData(new GridData(GridData.FILL_BOTH)); 

final ScrolledComposite scrolledComposite = new ScrolledComposite(container, SWT.H_SCROLL | SWT.V_SCROLL);
scrolledComposite.setExpandHorizontal(true);
scrolledComposite.setExpandVertical(true);

cmpNotificationBody = new Composite(scrolledComposite, SWT.NONE);
cmpNotificationBody.setLayout(new GridLayout(1, true));
scrolledComposite.setContent(cmpNotificationBody); 

final Composite scrollParent = new Composite(cmpNotificationBody, SWT.NONE);
final GridData data = new GridData(SWT.FILL, SWT.TOP, true, false, 1, 1);
data.heightHint = 100;
scrollParent.setLayoutData(data);
scrollParent.setLayout(new FillLayout(SWT.VERTICAL));

final ScrolledComposite scrollCmp = new ScrolledComposite(scrollParent, SWT.H_SCROLL | SWT.V_SCROLL);
scrollCmp.setExpandHorizontal(true);
scrollCmp.setExpandVertical(true);

final Composite cmpBody = new Composite(scrollCmp, SWT.NONE);
scrollCmp.setContent(cmpBody);

final FillLayout layout = new FillLayout(SWT.VERTICAL);
layout.spacing = 10;
cmpBody.setLayout(layout);
//make GUI 

scrollCmp.setContent(cmpBody);
scrollCmp.setMinSize(cmpBody.computeSize(SWT.DEFAULT, SWT.DEFAULT));
cmpBody.layout(); 
scrolledComposite.setContent(cmpNotificationBody);
scrolledComposite.setMinSize(cmpNotificationBody.computeSize(SWT.DEFAULT, SWT.DEFAULT));
cmpNotificationBody.layout();
