Hi,

I would like to add functionality to the UML2 editor context menu.
Can anyone tell me what the target ID is?

Cheers,

Samuel

Hi Samuel,

Have a look at org.eclipse.uml2.uml.editor plugin for
"org.eclipse.uml2.umlMenuID".

Cheers
- James.

Hi James,

I tried to create a ActionBarContributor (see attachment) and hook it
into the UML2 implementation. I initialize it in the 'selectionChanged'
method of my plugin. But it all didn't work. Do you have some more
concrete directions for me about how it should be done. Since I'm a
newbie to UML2, feel free to give a low level explanation.

Thanks,

Samuel

And here is the attachment and the code I use to initialize:

ArchiMateActionBarContributor contributor = new
ArchiMateActionBarContributor();
contributor.init((EditorActionBars) ((PartSite) workbenchPart.getSite())
.getActionBars());

Hi Samuel,

Have a look at org.eclipse.uml2.uml.editor plugin for
"org.eclipse.uml2.umlMenuID".

Cheers

Hi James,

I tried to create a ActionBarContributor (see attachment) and hook it
into the UML2 implementation. I initialize it in the 'selectionChanged'
method of my plugin. But it all didn't work. Do you have some more
concrete directions for me about how it should be done. Since I'm a
newbie to UML2, feel free to give a low level explanation.

Thanks,

Samuel
