Diagram partitionning [message #699379]

Hi everyone !

I followed this tutorial http://www.jevon.org/wiki/GMF_Diagram_Partitioning and i'm now able to open a new editor for a node.

I would like to know if it's possible to configure it for this case :
a subEditor for a class FOO

a class BAR with a FOO property, and a double clic on the BAR node opening the diagram for the FOO element.

Thanks in advance !

Valerian

Hi I did this by adding a OpenEditPolicy on the node (BAR in your case) and then extrated Foo the variable and build the string to represent the diagram name and then opened. Here is some code pasted together that might help (my code my spread over a number of class so I have done a quick copy / paste into one method for you):-

public class BAREditPart extends ShapeNodeEditPart {
/**
* @generated NOT
*/
private OpenEditPolicy createOpenEditPolicy() {
OpenEditPolicy policy = new OpenEditPolicy() {
protected Command getOpenCommand(Request request) {
Shell shell = new Shell();
// GET Attribute to that represents Diagram name to open
String aDiagramName = ((BARActionImpl)((NodeImpl)this.getHost().getModel()).getElement()).getFOOVariable().trim();
// Now build full path so diagram from the FOOVariable can be opened.
if (aDiagramName.length()!=0) {
XMIResourceImpl resource = (XMIResourceImpl)((ShapeNodeEditPart)this.getHost()).getEditingDomain().getResourceSet().getResources().get(1);
String pathString = ""+resource.getURI().toString().replaceAll("platform:/resource", "");
String tempString = pathString.replaceAll(resource.getURI().segment(resource.getURI().segmentCount()-1),"")+aDiagramName;
String fileString = tempString+".extention";
URI diagramModelFilename = URI.createPlatformResourceURI(fileString,false);
GMFResource myGMFDiagram = new GMFResource(diagramModelFilename);
try {
myGMFDiagram.load(Collections.EMPTY_MAP);
if (myGMFDiagram.isLoaded()) {
DiagramEditorUtil.openDiagram(myGMFDiagram);
}
} catch (IOException e1) {
} catch (PartInitException e) {
}
}
}
};
return policy;
}

Hope that helps a little

Dont forget to edit the createDefaultEditPolicies() Smile

e.g. My code was
installEditPolicy(EditPolicyRoles.SEMANTIC_ROLE,
new BARItemSemanticEditPolicy());
installEditPolicy(EditPolicy.LAYOUT_ROLE, createLayoutEditPolicy());
installEditPolicy(EditPolicyRoles.OPEN_ROLE, createOpenEditPolicy());
// remove the ability to add connections to node << This was for me you might not want this
removeEditPolicy(EditPolicyRoles.CONNECTION_HANDLES_ROLE);
}
