Hide node or container by default [message #1771763]

Hello,

Is it possible to hide by default a node or a container at its creation ?
I know that it is possible to hide a label by default in the label properties panel of a container gradiant style for example but I don't find how to hide the entire container or node diagram element.

Thank you,

Mathieu

Hi

Yes, it is possible.
You can call java code during your tool execution and then use the API to hide your element [1]
To call java code, simply add a ChangeContext operation in your tool and call you java code with aql.[2]

Note that the java code, called during a tool execution, is already executed in a EMF transaction. You don't necessarily need to add a Command in the CommandStack of the TransactionnalEditingDomain.

regards
Laurent
