Hiding elements [message #165877]

Hello,

I'd like to know how to programatically hide/show subelements of a node by
double-clicking on it. I managed to get the Double-click event and, at the
moment, I use the setVisible method but when I re-open the diagram the
subelements still appears. Can somebody tell me which is the right way to
hide an element?

Thank you,

David

Hi David,

org.eclipse.gmf.runtime.notation.View#setVisible() should be used to
persistently set visibility of the element. As always, this method
should be called from within an open transaction (see
AbstractTransactionalCommand for details).

Best regards,
Boris
