Hello everyone,

i am developing a gef-based application and i have created a diagram
using. Now i would like to get the entire diagram; is there any method to
do this? if so, how can i travel across the connections for getting each
of the figures contained in the diagram? Please, any idea.

Thank you very much.

getFigure() from the root (or contents) editpart. The editor also provides
it from its getAdapter() method.

Well, and when I get the diagram completely, how could I visit all the
figures (nodes) of the diagram, traveling across the connections between
the nodes?

Thank you very much

I have the following problem: when I get the root figure by calling the
getAdapter() method of the editor, I get null. The code I am using is the
following:



IEditorPart editor = PlatformUI.getWorkbench().getActiveWorkbenchWindow
().getActivePage().getActiveEditor();
IEditorInput input = editor.getEditorInput();

IFigure rootFigure = (IFigure)input.getAdapter(IFigure.class);
if(rootFigure==null){
System.out.println("rootFigure is null");
System.exit(1);
}
//List listaHijos=rootFigure.getChildren();

System.out.println("The number of children is
"+rootFigure.getChildren().size());



Well, this code always goes into the conditional and the program ends with
the System.exit() method. Why do I get a null rootFigure?

Please help, I need to solve this as soon as possible.

Thank you very much.

It's the editor you should be calling getAdapter on.

Stop and think about this for a second. The IEditorInput is normally
just a file, how in the world is it going to know anything about
editparts and figures????

and asking the editor for IFigure.class is not going to work either....
take a look at the editors implementation of getAdapter and it's easy to
see what you should be asking for.

Thank you Guy. I have taken a look to the implementation of the
getAdapter() method and I have noticed that the argument this method is
EditorPart.class. But now, I have another problem. In this way, the
connections between the figures aren't provided. How can I obtain them?

Thank you again.

IAdaptable.getAdapter(Class class)

getAdapter can accept any Class argument. You editor is a GEF editor,
right? Look at your editors implementation of getAdadpter and the
implementation of this method all the way up the class hierarchy of your
editor. Look at the Class arguments that they are able to handle. You
should be able to see what you should be passing and what it gives you
back. Remember, you want the root edit part...right?
