How to implement content assist's documentation popup in Eclipse RCP
问题 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);
