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

["Joe Dente" <jdente@xxxxxxxxxxxxxxxxxx>]

Upon further investigation, it does not seem possible to adjust the text and 
icons of a popup menu based on attributes in an EObject.  The icons are 
looked up based upon an EClass, not an EObject or instance of an EClass.  In 
the mindmap example, Depends, Extends, and Includes all share the same 
EClass (Relationship), meaning they all fetch identical text and icons for 
any popup menus.  So even though using OCL, the tooling and graphical 
definitions, I can assign different figures and tools to each of these 
relationships, there is no way to provide unique popup menus for using the 3 
different tools.  In my scenario, I have 14 different enum attribute values 
that have individual tooling, which would mean that the popup menus will 
have 14 identical appearing options that reference different tools!!! If I 
model these 14 different attribute values as 14 different classes, I can 
assign unique icons and text to the popup menus, but I lose flexibility in 
the way the user can edit and change the properties.

Is there a solution to this issue? It seems somebody out there would have 
run into this problem, especially since it exists in the Mindmap tutorial.

Thanks,
Joe
