[RCP] WorkbenchAdvisor vs plugin.xml (menus) [message #256590]

I'm starting to learn RCP and wondered whether declaring things in plugin.xml is
equivalent to creating them in my subclass of WorkbenchAdvisor. In particular,
I'd prefer to declare all my menus using actionSets extension point instead of
overriding fillActionBars method. However, it seems that if I don't create my
menu there it won't appear in the workbench. Here is a part of my plugin.xml
file (suppose fillActionBars is not overriden):

<extension
point="org.eclipse.ui.actionSets">
<actionSet
label="%actionSet"
id="actionSet">
<menu
label="%fileMenu"
id="file">
<groupMarker name="fileStart"/>
<separator name="fileEnd"/>
</menu>
<action
label="%quitAction"
class="org.eclipse.ui.internal.QuitAction"
menubarPath="file/fileEnd"
id="quitAction"/>
</actionSet>
</extension>

Note also that the same plugin declares extensions to
org.eclipse.core.runtime.applications and org.eclipse.core.runtime.products (if
this makes any difference).

Any help would be appreciated

They are equivalent but not interchangeable. Looking at your extract, the
QuitAction class your example wishes to contribute doesn't appear to
implement IWorkbenchWindowActionDelegate as expected by the <action> tag
(ergo "ClassCastException"). Take a look at IDEWorkbenchAdvisor. It
creates the standard menus and has a lot of the code you can emulate for
your own menus and those contributed by Eclipse plug-ins that you may wish
to reuse (e.g., text editor plug-in assumes you've created the standard Edit
pulldown).

You're absolutely right. I missed that (however no exceptions were thrown during
workbench startup). The point is that I'd like to reuse some common actions
(like Quit) but declare them in plugin.xml file if possible. It seems that I
could wrap org.eclipse.ui.internal.QuitAction instance with a class that
implements IWorkbenchWindowActionDelegate, I'll try that.

I will. Thanks for help.
