[news.eclipse.modeling.gmf] Re: To highlight an element on editor

[addur737@xxxxxxxx (Artur Kronenberg)]

Hi,

good that it worked for you. This is an additional information:

If you want to select things programmatically you should not use the 
XXXEditPart.setSelected(int type) method. There is a "correct" way of 
doing that.

You should get the viewer of your diagram (ParentEditPart.getViewer()) and 
use those methods:

setSelection(), setSelected(), appendSelection() 

those use EditPart Objects as atributes and that way the viewer handles 
everything else for you if your edit Policies work correctly.

To get the name of your atribute you need to access the implementation. 
you can get that by calling:

getModel().getElement() on your edit parts. you may need to cast the 
return valies. In the XXXEditPartImpl  there should be getName() method 
that returns you the name of the EditPart


I don't really know what you mean by "finding the addFeedBack() method". I 
think you want to set them highlighted. The appendSelection() on your 
viewer might also solve this problem for you. If not maybe you can 
describe that a little bit more and I will try explaining it if I can.

Best,
Artur
