I'm trying to add content assist to my editor. I've added
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;
}
to editor configuration, then made completion processor class:
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";
}
}
... 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?
