[EuGENia] Ordering of Tools, Adding custom menus, Drag'n'Drop [message #586968]

Q1: Is it possible to predefine the order of the tools in the tool palette through EuGENia. The order within the emf file is ignored and the tools are alphabetically ordered in the generated GMF editor. I was able the change the label of the tool grouping with an Ecore2GMF.eol:

var toolGroupObjects = GmfTool!ToolGroup.all.selectOne(r|r.title = 'Objects');
toolGroupObjects.title='Nodes';
Is this the supposed way ?

Q2: Can I add custom popup actions for specific nodes in the generated GMF diagram editor ? I need an action like replace node which will replace the node with an new node maintaining the incoming and outgoing links.

Q3: What is the supposed way to add a custom drag-and-drop handler to the GMF editor

Yes. You can use EOL to re-order the tools (or even create new tool
groups) as you see fit. Please let me know if you need an example and
I'll try to put together one.

Yes. This article will probably help a lot:

Google returned this: http://www.jevon.org/wiki/GMF_Drag_Drop If this
is not what you're looking for I'd suggest asking in the GMF newsgroup.

Cheers,
Dimitris
