R3.1.1, WinXP
The newsgroups, the HTML-help in Eclipse, and the javadocs that I have looked at say nothing about
this.
I have a context-menu (an objectContribution) defined in my plug-in; it works fine, items show up,
they act the way they should. Some of them even have submenus defined (see the extract from
plugin.xml below).
Now, I want to take one of those submenu actions -- the "restrict type" -- and *dynamically*
populate its submenu depending upon the value of the current type (e.g., if the current type is
"VDT" I might want to populate with "Plasma", "CRT", and "LCD"; whereas if the current type is
"Mouse", I might want to populate with "USB", "Wireless", and "Standard").
How do I do that? (I know how to do it if the *menu* itself is *not* created by the plugin.xml,
i.e., in the menuAboutToShow(IMenuManager) method.)
thanks,
Paul

Set the class style="pulldown". Make your action implement
IObjectActionDelegate and IMenuCreator. On the first call to
selectionChanged, call setMenuCreator on the IAction you are passed. See
org.eclipse.debug.ui.actions.ContextualLaunchAction (in
"org.eclipse.debug.ui") for an example.
cheers,
d.
