Delegating controls to receive events

Thread view:

I want to have a comboxbox and an elipsis ... button treated as a
single control.

If I use a JPanel + BorderLayout with a combobox using the 'Center' and
the button the 'East'

[________] [...]

For most interactions I want the events to go to the combobox. Rather
than overloading and redirecting each individual JPanel method, can I
somehow delegate the combobox to receive everthing by default.

Then I would code a few specific things for the elipsis button.

Huh? Do you write a custom component?

Sure, if you want to call treated panel+combo+button a 'custom
component'.

Putting them together simplifies the layout and interface code
significantly.

No. A custom component is something that is a (indirect) subclass of
(J)Component. To treat two components like one might be related to e. g.
instance creation only.

If *this* is the intention for your proposition, then I have to say that
there's absolutely no need for creating a custom component and I would
give the advise to forget it.
