SWT独立滚动条小部件 [英] SWT standalone scrollbar widget

问题描述

是否可以在SWT中创建独立"滚动条?我想拥有一个可以完全控制自己的滚动条，并使用它来控制另一种控件的内容，例如，使用Table控件中的内置"滚动条是不可能的.

Is there a way to create a "standalone" scrollbar in SWT? I would like to have a scrollbar which I have full control over myself and use it to control the contents of another widget in a way which isn't possible with the "built-in" scrollbars in the Table widget, for example.

推荐答案

我同意您可能无法单独获得滚动条，但是我已经通过使用Canvas(或ScrolledComposite)解决了该问题，然后设置了内容该组合的大小与ScrolledComposite.getClientArea()的大小完全相同.这可能需要进行一些微调，并且您必须确保内容组件与ScrolledComposite一起调整大小，但是应该可以.

I agree that you probably can't get a scrollbar alone, but I've worked around that with using a Canvas ( or ScrolledComposite ) and then set the content of that composite to exactly the same size as the ScrolledComposite.getClientArea(). That may require a bit fine tuning and you have to make sure that the content component resizes together with the ScrolledComposite, but should be possible.

然后，您可以获取ScrolledComposite的滚动条，并独立于ScrolledComposite使用它们.

You can then get the Scrollbars of the ScrolledComposite and use them independently of the ScrolledComposite.
