Providing Search Functionality in GEF [message #116248]

Hi,

I am trying to provide a search fn. in GEF. Using GEF i have created a
tool via which one can build arbitrary model diagrams(similar to UML).Now
i was thinking,given a model element name in the search dialog,the whole
model is "parsed" and the relevant matches are shown in the search view.On
click of a search entry the corresponding elemnt gets highlighted in the
GEF Editor and outline view.

My problem is with creating the search markers. The IMarker interaface is
expecting IResource,and only way u can create a marker is
resource.newMarker() and also the IMarker interface has keys like
CHAR_STAR,CHAR_END etc which has no meaning in my case.I dont have
IResource too.[Probably i should get the handle to the file in which i
have stored my model and use it???].But what i would really like to do is
attach teh marker to my model objects rather than the file.Any ideas????

Try looking at what the jface.text stuff does. I believe they have
something called an IAnnotation(Model?), which does not require an
IResource. I think also that markers are extensible, so you could provide
additional properties if you wanted.

If your model doesn't map to resources (files) then you should follow the
documentation (JavaDoc/Developer Guides) and attach the marker to the
workspace root (which is a resource).

Add your own properties for a unique model id or something similar.
