如何在Eclipse RCP中实现内容帮助的文档弹出窗口

问题描述

我已经实现了自己的编辑器并添加了一个代码完成功能。我的内容助手在源代码查看器配置中注册：

I have implemented my own editor and added a code completion functionality to it. My content assistant is registered in source viewer configuration like this:

public IContentAssistant getContentAssistant(ISourceViewer sourceViewer) {
    if (assistant == null) {
        assistant = new ContentAssistant();
        assistant.setDocumentPartitioning(getConfiguredDocumentPartitioning(sourceViewer));
        assistant.setContentAssistProcessor(getMyAssistProcessor(),
                MyPartitionScanner.DESIRED_PARTITION_FOR_MY_ASSISTANCE);
        assistant.enableAutoActivation(true);
        assistant.setAutoActivationDelay(500);
        assistant.setProposalPopupOrientation(IContentAssistant.PROPOSAL_OVERLAY);
        assistant.setContextInformationPopupOrientation(IContentAssistant.CONTEXT_INFO_ABOVE);
    }
    return assistant;
}

当我按 + + inside the desired partition, the completion popup appears and works as expected.

这是我的问题..如何实现/注册出现的文档弹出窗口旁边完成弹出窗口？ （例如在java编辑器中）

And here's my question.. How do I implement/register a documentation popup that appears next to completion popup? (For example in java editor)

推荐答案

嗯，

我自己会问这个问题; - ）

I'll answear the question myself ;-)

你必须添加这一行

assistant.setInformationControlCreator(getInformationControlCreator(sourceViewer));

到上面的配置。然后，当创建 CompletionProposals 时，构造函数的第八个（最后一个）参数称为 additionalProposalInfo ，该文本将显示在文档弹出窗口中。

to the configuration above. Then when creating CompletionProposals, the eighth (last) parameter called additionalProposalInfo of the constructor is the text, which will be shown in the documentation popup.

new CompletionProposal(replacementString,
                          replacementOffset,
                          replacementLength,
                          cursorPosition,
                          image,
                          displayString,
                          contextInformation,
                          additionalProposalInfo);

容易，不是吗？如果你知道该怎么做;）

Easy, isn't it.. if you know how to do it ;)
