[news.eclipse.modeling.gmf] Re: Change Popup Strings and Icons in Mindma

[kojihashi@xxxxxxxxx (Koji Hashimoto)]

Joe,

You can change the text of a popup menu by modifying the "name" attribute 
of ElementType. ElementTypes are registered in 
org.eclipse.gmf.runtime.emf.type.core.elementTypes extension point.

To customize the icons, from p.12 to p.24 of the following slides will 
help you.
