Content assistant provided? [message #755805]

Hey,

is there a way to support content assistance while direct editing of
texts with graphiti? I'd like to add a Content Assistant for OCL
expressions.

best regards,

Lilija

Alexander Nyßen had a preentation on work done to include Xtext editors inside GMF. See http://eclipsecon.org/sessions/tmf-meets-gmf-combining-graphical-and-textual-modeling.

This turned out to almost be GMF independent, and is a good basis for getting this inside Graphiti. This can solve your problem.

Besides to what Jos wrote, you can provide copletion values by implementing
AbstrctDirectEditingFeature.getValueProposals for text edit fields.

Hi all,

I have implemented a test of content assist by putting

 @Override
    	public String[] getValueProposals(String value, int caretPos,
    			IDirectEditingContext context) {
    		System.out.println("___________________________");
    		return new String[] {"A","B"};
    	}

in my direct editing feature. However, the code does not seem to be called. What is the keycode to invoke the content assist in a direct editing text?

Thanks,

Andreas

Andreas,

the key to invoke auto completion is CTRL-Space (as in standard Eclipse text
editors). Did you enable auto completion in your direct editing feature by
retunring true in the methods isCompletionAvailable and
isAutoCompletionEnabled?
