Hi Marius,

> embedding in Swing

You can mix and match AWT and Swing components, so if you can tolerate
ImageJ 1.x's use of AWT, you may be all set.

Alternately, the ImageJ2 project has a more flexible UI plugin system,
which includes a Swing-based UI closely modeled after the ImageJ 1.x
interface: https://github.com/imagej/imagej-ui-swing

However, ImageJ2 UIs other than the "legacy" interface have very limited
support for ImageJ 1.x plugins.

Given your requirements, it would probably be the least effort to use
ImageJ1 as an applet, and tolerate its AWT-isms.

If you use ImageJ2, there is limited support for running ImageJ1 code
headless; see:
    http://imagej.net/Headless

The ImageJ2/SciJava architecture uses an event bus for all its event
handling:

https://github.com/scijava/scijava-common/blob/scijava-common-2.35.1/src/main/java/org/scijava/event/EventService.java

But that won't help you w.r.t. ImageJ 1.x functionality.

Regards,
Curtis
