Hi

I want to perform some operation on all the elements in each of the
diagram files for all the project in the workspace.
I am able to get the diagram and the model filename as a IResource
object.How could i get the editPart from the filename

for now i have pasted the code by which i can get the diagram/model
fileName

IProject[] projects = null;
IProject p = null;
IFolder file = null;
IResource[] members = null;
IResource[] newFile = null;

IWorkspace workspace = ResourcesPlugin.getWorkspace();

// gets all the projects in the workspace
projects = workspace.getRoot().getProjects();
for (int i = 0; i < projects.length; i++) {
p = projects[i];
}
try {
// gets all the folders in the project
members = p.members();
}catch (Exception e){

}

file = (IFolder) p.findMember("<myrequiredfolder>");

try {
newFile = file.members();
}catch(Exception e){

Hello sowmya,

You have to open an editor then you'll be able to interact with EditParts.
I suggest you to use Notation/DomainModel API for these modifications. Nearly
all the necessary information is available through these APIs.
To get Notation model instances you simply have to load EMF resource from
the diagrfam file and then you'll see Diagram instance just in the root of
this resource.

Thanks Alex.
But i am trying to get the diagram editparts without opening the diagram
file.

At the time of launching the runtime workbench i am retriveing all the
projects and the diagram files in it. I need to perform some check for all
the elements in all diagram files in all projects before the runtime
launches completely .

Is there any way i can be doing this

Hello sowmya,

As I already said, you can use Notation model API to perform nearly all the
checks/modifications you need (without openning an editor).
Another option (if you really need EditParts) is to open diagram in a viewer
without actual UI. This is a GEF-related question and AFAIK GEF allows it.
