What is the general approach in implementing this button as a part of =

Joe,
Thank you for your kind response. It helps me move in the right direction.
In the meantime, I would like to clarify that the pop-up I am looking for is
quite generic and not related to VE per se. In my case, the property editor
is used for a regular GEF editor, and I need to be able to customize the
drop list in the property editor via a pop-up dialog.
Thanks again.

I presume you have your own JavaBean with a property where you want to
do this. The simplest way is to create a BeanInfo class and specify a
property editor, although this doesn't give you the ability to have
combo and additional editor. It is fairly straightforward however and
doesn't involve writing any Eclipse code - you just create a
java.beans.PropertyEditor for the java.beans.PropertyDescriptor and
specify whether you have tags (which creates a drop down list) or a
custom editor (in which case the ... button will appear allowing it to
be launched)
However if you want a combo and drop down provided you must write an
Eclipse plugin. There are several steps involved and we do intend to
document this property shortly, however I'll give you the rough pointers .
First - create a plugin. This will use the beaninfo.overrides extension
point and declares to the Visual Editor the location of a /overrides
folder containing information about your JavaBeans. Look at the
org.eclipse.ve.jfc (Swing plugin) to see how this is done.
Second - create a .override file for your JavaBean. This is an XMI file
that contains the delta that will be applied to your introspected
JavaBean. The format can be quite tricky to read at first, but the best
thing to do is copy an existing one (perhaps AbstractButton that has a
mnemonic property that's very similar to what you want to do) and rename
stuff and chop out what looks like it doesn't belong. The only thing
you really want in the file is a PropertyDescriptorDecorator that
specifies a cellEditorClassName.
Third - create a cellEditorClassName. This is a standard JFace cell
editor but it has to implemented a few extra interfaces. Look at the
Font one to get ideas to steal from.
I'm sorry this is such a brief reply right now, but we do intend to
write more complete documentation on how to extend the Visual Editor and
adding custom property editors is one of the examples that will be
covered. Let us know how you get on or whether you want me to expand
any of the steps in more detail.
Best regards,
Joe Winchester
