Problem with EditPart and Impl [message #232532] Fri, 05 June 2009 09:06 Go to next message

Hi, I have to hide a node B when I click on oneother node A. In my
meta-model A has a reference to B. I install an OpenEditPolicy in A so
when I double-click on A I can hide B. From the EditPart A I call "aview =
(View)A.getModel()" to obtain the model of A. Now I can get B calling "b =
aview.getB()".. The class of b is "BImpl". Now, how can I hide B using
this BImpl class? I try to cast as View but I get an error. There is a
way to get the EditPart of B starting from the BImpl class?
Thanks

Sorry i forget a step..
When I obtain the view "aview" I call "(A)aview.getElement()" to get the
model and I obtain an "AImpl" instance and then I call "getB" to get
"BImpl".

Hello Giordano,

Having BImpl you should traverse all Nodes starting from the current diagram
to find notation model element (Node) representing BImpl on this diagram.
Then you can use EditPartRegistry to find EditPart representing this view
like: EditPartViewer.getEditPartRegistry().get(<Node>).

EditPartViewer is available form any EditPart - there is .getViewer() method.

Your method works only when EditPart is visible.. when I hide B
getEditPartRegistry returns null..
How can I handle this? I need to show B the next time I double-click on A!
Thanks for your time!!

Hello Giordano,

How do you hide B? If you are calling View.setVisible() then you do not need
EditPart..

I'm not if this can help if the View of EObject B is invisible, but the
simples method to get from an EObject to a View Object is by calling:

ViewUtil.getViewContainer(EObject)

Something similar is possible to get an editpart (if the editor is open
and focussed by calling

..findEditPart(EditPart epToBegin,EObject theElement)

this must be called on any parent of the editpart your're looking for
which then is the first argument as well (I always take the
DiagramEditPart).theElement corresponds to the semantic element for
which you search the editpart.

I'm not sure if they work if the editpart is hidden, but I can't imagine
why not :)

Hope that helps,
Daniel
