Getting back to this rather old thread, we generally do have applet
integration working using the SWT Browser widget which works more or less
well except for two different issues:
(a) Having a Browser widget located in a certain view, I see the applet got
disposed as soon as the view lost focus and, subsequently, got restarted as
soon as the view got focused again. This, in our case, is rather painful as
loading this applet takes some time.
(b) In case of our applet (a document viewer), JavaScript commands / applet
scripting can be issued to make the applet do things, like opening
documents, saving markup, ... . Using a "simple" Browser widget however,
this kind of interaction with the applet in a view is hardly possible.
So to ask: Does anyone have any experience in doing an applet integration
"tighter" than just Browser/iframe to compensate for (or eventually even
overcome) both limitations (a) and (b)?
Thanks in advance and all the best,
Kristian

Kristian,
I haven't tested an applet with a UI, but I've been doing some experiments
with using an applet for background processing on the client. I created a
custom qooxdoo widget similar to the google maps example. Communication
between java and javascript is working. I would be happy to share some of
the code if you are interested.
I'm not sure about sizing of the applet, maybe that's why people are
suggesting an iframe. It should be pretty easy to test it out. When I get
to work tomorrow, I'll take a look and pass the code along.
