Re: [Dltk-dev] org.eclipse.dltk.ui.completion + proposalLabelProvider /

[Alexey Panchenko <alex.panchenko@xxxxxxxxx>]

Hi Robert,

If I understand your case correctly it can be done by implementing
org.eclipse.dltk.ui.text.completion.IScriptCompletionProposalFactory.
Which is designed as external extensibility, while
CompletionProposalLabelProvider is an internal one at the moment.

Regards,
Alex
