I get the Diagram from digramfile, and then I use copyToImageUtil to create
a diagramEditPart based on the diagram. List codes below:
final Display display = Display.getDefault();
final Shell shell = new Shell();
shell.setSize(600,800);
shell.setText("testcopytoutil");
IPath resourcePath = diagramFile.getFullPath();
ResourceSet resourceSet = myEditingDomain.getResourceSet();
try {
Resource modelResource = resourceSet.getResource(
URI.createPlatformResourceURI(resourcePath
.toString()), true);
if(modelResource instanceof XMIResourceImpl){
Object[] objs = getElements(modelResource);
CopyToImageUtil copyToImageUtil = new CopyToImageUtil();
diagramEditPart = copyToImageUtil.createDiagramEditPart((Diagram)
objs[0],new Shell(),ProcessDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT) ;
}
} catch (WrappedException e) {
ProcessDiagramEditorPlugin
.getInstance()
.logError(
"Unable to load resource: " + resourcePath.toString(), e);
//$NON-NLS-1$
}
shell.layout();
shell.open();
while(!shell.isDisposed()){
if(!display.readAndDispatch())
display.sleep();
The code works well without reporting error, but I can not see anything from
the shell shows up....So I suspect if I did right?
By the way, I use the diagramEditPart which is returned by
copyToImageUtil.createDiagramEditPart method to get the commands to create
view on it, then how to save the Diagram? I know if it is an editor, I can
use editor.doSave(), but it is Ddiagram, how to save it back to its
diagramfile.

Hello,
No, you shouldn't see the diagram in the shell. This method allows you
to create a DiagramEditPart without creating an editor. You could then
use the DiagramEditPart for whatever reason you needed it. For example,
GMF uses this mechanism to create an image from a diagram (see
CopyToImageUtil.copyToImage()).
