java - Tabfolder 中的 ScrolledComposite

Question

我正在努力获取选项卡文件夹中的可滚动区域......不知道我哪里出错了...如果我在这方面得到一些帮助，那就太好了......

    public void createCustomControl(Composite parent)
{
    parent.setLayout(new GridLayout());


    tabFolder = new TabFolder(parent, SWT.H_SCROLL |SWT.V_SCROLL);

    ScrolledComposite scroll = new ScrolledComposite(tabFolder, SWT.V_SCROLL|SWT.H_SCROLL);
    scroll.setExpandHorizontal(true);
    scroll.setExpandVertical(true);     
    GridData scrolledData = new GridData(GridData.FILL_BOTH | GridData.GRAB_HORIZONTAL
            | GridData.GRAB_VERTICAL);
    scroll.setLayoutData(scrolledData);

    Composite result = new Composite(scroll, SWT.NONE);
    GridData resultData = new GridData(GridData.FILL_BOTH |     GridData.GRAB_HORIZONTAL
            | GridData.GRAB_VERTICAL);
    result.setLayoutData(resultData);

    scroll.setContent(result);

    scroll.setMinSize(scroll.computeSize(SWT.DEFAULT, SWT.DEFAULT));
    tabFolder.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

您需要创建一个 TabItem 并通过调用 setControl() 为其分配 ScrolledComposite。仅当子选项卡文件夹分配给选项卡项目时，选项卡文件夹才会显示子选项卡文件夹。

在代码末尾添加以下行:

final TabItem tabItem = new TabItem(tabFolder, SWT.NONE);
tabItem.setControl(scroll);
