-- This menu will only be on selected items that implement the
IJavaBeanContextMenuContributor interface. In our case the selected
objects from the VE will always be gef EditParts and all of the Java
Beans Editparts will implement this interface. This interface tells us
that the object is a java bean that we can things about (see below).

-- This is your unique id for the action you are adding.

- IJavaBeanContextMenuContributors understand filters and certain
filter names, such as BEANTYPE and PROPERTY. In this case BEANTYPE says
that this action will only show on Editparts that are for an
org.eclipse.swt.widgets.Control bean.
> <filter name="PROPERTY" value="data"></filter>
- IJavaBeanContextMenuContributors understand "PROPERTY" to. This says
that it will be visible if the bean (a subclass of Control in this
example) has the property "data".
The rest below is standard popup contributor stuff.
> <action

> </objectContribution>
So this entire contributions says that this menu item will only show up
when all three below are true:
1) Selected items that implement IJavaBeanContextMenuContributor
2) The Bean that selected item represents is an instanceof (including
subclasses) of org.eclipse.swt.widgets.Control
3) The Bean that selected item represents has a property named "data".
If not all three are satisfied, then the popup will not have this action.
There are other filters available to the
IJavaBeanContextMenuContributor. Take a look at the class
org.eclipse.ve.internal.cde.core.CDEActionFilter to see what filters are
available for general beans.

Yeah, none of that has been made into an api and documented yet. :-(

The code generation part is done by someone else.

while looking at SWTLabelCreationPolicy.java and
ChangeParentShellObjectActionDelegate.java, I have tried out the
following code to do the insertion. (basically it will set the property
"data" to a string.) It seems to work, but not sure if this is the
correct way to do it.
IJavaObjectInstance model = (IJavaObjectInstance)
selectedEP.getModel(); EStructuralFeature esf =
model.eClass().getEStructuralFeature("data");
ResourceSet rs = model.eResource().getResourceSet();
IJavaObjectInstance ijoi = BeanUtilities.createString(rs,"test");
RuledCommandBuilder cb = new
RuledCommandBuilder(EditDomain.getEditDomain(selectedEP));
cb.applyAttributeSetting((EObject) model, esf, ijoi);
command = cb.getCommand();
command.execute();
Another question : After running the above code, a new expression is
inserted : for example: button.setData("test");
However, I want it to say : button.setData("id","test"); instead. I
looked at BeanUtilities and RuledCommandBuilder.applyAttributeSetting,
but I couldn't find a way to do it.
Thanks for all your help.

yep. That would be the right way to get the default behavior (property setting has a single argument). But also, Since
VE consider "data" to be a property, you can only set it once. i.e., if you try to create a sequence of
setData(key,data) calls VE will replace them. Is this a problem?

I don't know how to insert setData(key,data), and that's what my question is. Actually, I prefer VE
to replace them, so VE's behavior would be perfect in my case. Any idea how can I modify my code to
insert setData(key,data) instead of setData(data)? Thanks.
