如何在 Eclipse RCP 应用程序中使视图可滚动?-Java问题

问题描述

到目前为止我尝试了什么:

What I tried so far:

在 createPartControl 中:

In createPartControl:

ScrolledComposite sc = new ScrolledComposite(parent, SWT.V_SCROLL | SWT.H_SCROLL);
        sc.setLayoutData(new GridData(GridData.FILL_BOTH));
        sc.setExpandVertical(true);
        sc.setExpandHorizontal(true);
        sc.setSize(ApplicationWorkbenchWindowAdvisor.WIDTH, ApplicationWorkbenchWindowAdvisor.HEIGHT);
        final TabFolder tabFolder = new TabFolder(sc, SWT.TOP);

但这不起作用.我的问题是，如果我调整程序窗口的大小，滚动条不会出现在我的视图中.有什么想法吗?

but this does not work. My problem is that if I resize my program window the scrollbars does not appear in my view. Any ideas?

推荐答案

ScrolledComposite的Javadoc描述了两种使用方式，包括示例代码.总结一下:

The Javadoc of ScrolledComposite describes the two ways to use it, including example code. To sum them up:

您可以在控件/复合体本身上设置 ScrolledComposite 中包含的控件/复合体的大小
或者您告诉 ScrolledComposite 用于其内容的最小尺寸.

You either set the size of the control/composite contained in your ScrolledComposite on the control/composite itself
Or you tell your ScrolledComposite the minimum size to use for its content.

目前，您两者都不做.您在 ScrolledComposite 上设置大小，但除非您不使用布局管理器，否则这没有多大意义.无论如何，请参阅上面的链接以获取一些官方示例代码.

Currently, you're doing neither. You're setting the size on the ScrolledComposite, but unless you don't use a layout manager, that doesn't make much sense. In any case, see the above link for some official example code.
