I wish to change some visual properties of nodes and connections. How better can it be done? I found that visual information is applied in model factory that is returned from org.eclipse.zest.core.viewers.GraphViewer.getFactory(). There are three factories and all are placed in internal package org.eclipse.zest.core.viewers.internal.
Is it good approach to override org.eclipse.zest.core.viewers.GraphViewer.getFactory() and return own factory that does all necessary styling actions?
There is interface org.eclipse.zest.core.viewers.ISelfStyleProvider which solves my problem without hacking into zest internal structure!
