Adding Content Assist to a WrappingLabel? [message #556095]

Hi,

I need to add Content Assist to a WrappingLabel (org.eclipse.gmf.runtime.draw2d.ui.figures.WrappingLabel).

I had hoped to do this with an ContentProposalAdapter (org.eclipse.jface.fieldassist.ContentProposalAdapter), but the ContentProposalAdapter expects a Control (org.eclipse.swt.widgets.Control) like org.eclipse.swt.widgets.Text .

Any ideas on how to do this? I searched around but can't find any examples where Content Assist was used for anything other than org.eclipse.swt.widgets.Text or texteditors (like this).

I guess I am in way over my head.

This post is very old, but I had the same problem and gmf is still used.

I solved the problem by implementing the getCompletionProcessor in my TextAwareLabelEditPart and returning a class implementing IContentAssistProcessor and ISubjectControlContentAssistProcessor. The later is deprecated, but the other ways for getting a content proposal lead otehr difficulties, like no NullPointer because missing ITextViewer.

Hi,

you should take a look to this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=371888
See also XText integration from Yakindu (related to the mentioned bug): http://muelder.blogspot.fr/2011/04/xtext-celleditor-integration.html
it will allow you to use whatever kind of DirectEditor and so on provide contentassist that you want.
