问题描述

我使用SWT设计了一个带有文本字段的向导页面.我想向文本字段添加内容辅助，即当我按"Ctrl +空格"时，它必须提出数据列表.有任何实现此功能的标准方法吗?

I have designed a wizard page with a text field using SWT. I want to add a content assist to the text field i.e , when i press 'Ctrl+space', it has to propose the list of data. Any standard method to implement this feature?

推荐答案

您可以使用JFace ContentProposalAdapter在Text控件上执行此操作.

You can use the JFace ContentProposalAdapter to do this on a Text control.

使用类似的东西:

Text textControl = ....


KeyStroke keyStroke = KeyStroke.getInstance("Ctrl+Space");

new ContentProposalAdapter(textControl, new TextContentAdapter(), provider, keyStroke, null);

provider是实现IContentProposalProvider的类，它只有一个方法getProposals:

provider is a class implementing IContentProposalProvider this just has one method getProposals:

@Override
public IContentProposal [] getProposals(String contents, int position)
{
  // TODO return array of `ContentProposal` objects appropriate to the contents
}
