content assistant [message #176706] Wed, 07 January 2004 13:34 Go to next message

I'm trying to add content assistance to an editor I'm writing. However, in
the Edit-menu the item "Content assist" is not showing up.
For this part of the editor I'm relying on the code from a book "The Java
developer's guide to Eclipse" from Shavor. I essentially copied the code
from that book. It does, however, not seem to work (i.e. Ctrl+Space does
nothing).

The code below is what, to my knowledge, should get content assistance to
work:

public IContentAssistant getContentAssistant(ISourceViewer sourceViewer) {
ContentAssistant assistant;
assistant = new ContentAssistant();
assistant.setContentAssistProcessor(
new MyCompletionProcessor(),
IDocument.DEFAULT_CONTENT_TYPE);
assistant.enableAutoActivation(true);
assistant.setAutoActivationDelay(500);
assistant.setProposalPopupOrientation(
IContentAssistant.CONTEXT_INFO_BELOW);
assistant.setContextInformationPopupOrientation(
IContentAssistant.CONTEXT_INFO_BELOW);
assistant.enableAutoInsert(true);
return assistant;
}

However, I'm probably forgetting something. Could someone point out to me
what I should do to get it to work.

What's going on in MyCompletionProcessor? Specifically, what's inside
computeCompletionProposals?

Do you have a properties file configured for the plugin?

There is an errata for this chapter that might be the cause. See errata on
this page:
http://www.awprofessional.com/catalog/product.asp?product_id ={DF615A81-6FB0-
4130-9EA4-E2D0BEF340E3}. I thought the publisher did a fairly good job of
hiding this page <g>. If that's not it, repost and I'll bring it to Scott's
attention.

This is what happens in MyCompletionProcessor:

public ICompletionProposal[] computeCompletionProposals(ITextViewer
viewer, int documentOffset) {

WordPartDetector wordPart =
new WordPartDetector(viewer, documentOffset);

// iterate over all the different categories
for (int i = 0; i < allWords.length; i++) {
String[] list = (String[]) allWords[i];
// iterate over the current category
for (int y = 0; y < list.length; y++) {
if (list[y].startsWith(wordPart.getString().toUpperCase()))
proposalList.add(list[y]);
}
}

return turnProposalVectorIntoAdaptedArray(wordPart);
}

protected ICompletionProposal[]
turnProposalVectorIntoAdaptedArray(WordPartDetector word) {

ICompletionProposal[] result =
new ICompletionProposal[proposalList.size()];

int index = 0;

for (Iterator i = proposalList.iterator(); i.hasNext();) {
String keyWord = (String) i.next();

IContextInformation info =
new ContextInformation(keyWord, getContentInfoString(keyWord));
//Creates a new completion proposal.
result[index] =
new CompletionProposal(keyWord,
word.getOffset(),
word.getString().length(),
keyWord.length(),
null,
keyWord,
info,
getContentInfoString(keyWord));
index++;
}

proposalList.removeAllElements();
return result;
}

Regretfully, the code concerning content assistance remains the same

Hi,

I think you have to register the appropriate actions for your editor as
well. For example to use the content assistant feature for your editor you
need to do something like that:

public class YourEditor ...
{
....
protected void createActions()
{
super.createActions();

// Creates action for content assist (Ctrl+Space)
IAction action = new
TextOperationAction(TranslatorEditorMessages.getResourceBund le(),
"ContentAssistProposal.", this, ISourceViewer.CONTENTASSIST_PROPOSALS);

action.setActionDefinitionId(ITextEditorActionDefinitionIds. CONTENT_ASSIST_P
ROPOSALS);
setAction("ContentAssistProposal", action);
...
}
....
}

And in the resource bundle you use in TextOperationAction you can use
something like that:
ContentAssistProposal.label=Content Assist@Ctrl+SPACE
ContentAssistProposal.tooltip=Content Assist
ContentAssistProposal.image=
ContentAssistProposal.description=Content Assist

After doing this Ctrl+Space should work.

For including content assist in the context menu (and the main Edit menu)
read Eclipse help-->Platform Plug-in Developer Guide-->Programmer's
Guide-->Editors-->Registering editor actions for details, it may help you.

HTH,
Regards,
Csaba
