AW: [pde-dev] dynamically changing pop-up menus

[Kristian Köhler <koehler@xxxxxx>]

Hi

I'm not sure if this helps:

In the snipplet section for SWT you can find an example for a dynamic menu.

Snipplets:
http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/platform-swt-home/dev.ht
ml#snippets

Example:
http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/platform-swt-home/snippi
ts/snippet73.html

Hope this helps.
