POEclipse RCP - Content Assist trouble
text
Body
copied!<p>I'm trying to add content assist to my editor. I've added</p> <pre><code> public IContentAssistant getContentAssistant(ISourceViewer sv) { ContentAssistant ca = new ContentAssistant(); IContentAssistProcessor pr = new TagCompletionProcessor(); ca.setContentAssistProcessor(pr, XMLPartitionScanner.XML_TAG); ca.setContentAssistProcessor(pr, IDocument.DEFAULT_CONTENT_TYPE); return ca; } </code></pre> <p>to editor configuration, then made completion processor class:</p> <pre><code>public class TagCompletionProcessor implements IContentAssistProcessor { private ITypedRegion wordRegion; private String currentWord; private SmartTreeSet tags; public TagCompletionProcessor() { tags = new SmartTreeSet(); //filling tags skipped } @Override public ICompletionProposal[] computeCompletionProposals(ITextViewer viewer, int offset) { System.out.println("compute"); wordRegion = viewer.getDocument().getDocumentPartitioner().getPartition(offset); try { int offs = wordRegion.getOffset(); int len = wordRegion.getLength(); currentWord = viewer.getDocument().get(offs, len); return tags.getProposals(currentWord.toLowerCase(), offs, len); } catch (BadLocationException e) { return null; } } @Override public IContextInformation[] computeContextInformation(ITextViewer viewer, int offset) { return null; } @Override public char[] getCompletionProposalAutoActivationCharacters() { return new char[] {'<'}; } @Override public char[] getContextInformationAutoActivationCharacters() { return null; } @Override public IContextInformationValidator getContextInformationValidator() { return null; } @Override public String getErrorMessage() { return "No tags found"; } </code></pre> <p>}</p> <p>... but it's not working. Init goes normal, but auto-activation does not working and when I'm pressing ctrl-space (I've added org.eclipse.ui.edit.text.contentAssist.proposals command to Bindings ext point) empty list appearing (also it's not near cursor, but in some constant place). What am I doing wrong?</p>
