Thank you Anthony.
Looking at GEF Logic Editor I see:
protected void setInput(IEditorInput input) {
superSetInput(input);
IFile file = ((IFileEditorInput)input).getFile();
try {
InputStream is = file.getContents(false);
ObjectInputStream ois = new ObjectInputStream(is);
setLogicDiagram((LogicDiagram)ois.readObject());
ois.close();
}
// other stuff
}
OK I'll do it here. But:
Given that I don't have access to org.eclipse.core.resources.IFile,
But I do have org.eclipse.core.runtime.IPath;
How do I cast IEditorInput to MyPathEditorInput so that I can have
access to it's public IPath getPath() method?
Thanks,
your help is greatly appreciated.
