hello all,
suppose in my diagram there are several nodes like: NODE1, NODE2. and they have some properties like length, start time, end time.
there should be some constrains like length should be less then 10. difference between start time and end time is 120 sec. if it doesn't fulfill this limitation the NODE should become RED.So I need your help...

Hi,

you can use the new GMF 3.0 functionality to do so. In your graphical model define a diagram pin (Color pin) for this. In the GMFMap model you can define a constraint (Visual Effect Mapping) on when to use which. Alternatively you can hard code it into yout editparts. Here is an Example for one of my templates: http://code.google.com/a/eclipselabs.org/p/melanie/source/browse/de.uni_mannheim.informatik.swt.models.gmf/templates/aspects/diagram/editparts/NodeEditPart.xpt Take a look at updateView() and from where it is called.

Ralph
