It would be very nice to embed XULRunner/Firefox into Eclipse/SWT for XUL preview and/or live editing inside Eclipse.
You can help us by voting for this Eclipse feature Allow Firefox as browser widget.

XUL WYSIWYG Editor alternatives
Using Visual Editing Framework
The Eclipse Visual Editor project is a vendor-neutral, open development platform supplying frameworks for creating GUI builders, and exemplary, extensible tool implementations for Swing/JFC and SWT/RCP.
Pros: Using this framework it is possible to (re)implement XUL (Layout/Widgets etc) to get (nearly) the same rendering result as gecko.
Cons: The rendered result will not 100% the same as gecko's layout (no real wysiwyg...). Furthermore this solution might not reflect special behaviour of different gecko version (for example canvas element supported/not supported and so on).
We may turn out to be able to use the xulcreator stuff based on SWT by RJ Keller, I think he's doing stuff that may be reusable. --AxelHecht 08:06, 25 Aug 2005 (PDT)
Just found ide4lazlo, which has some interesting screenshots.
It is (in general) possible to embed a Mozilla/Gecko Window into Eclipse/SWT on every platform supported by Mozilla and SWT.
We could build the WYSIWYG editor as Multipage editor and embed the Mozilla XUL Window as WYSIWYG Preview.
Pros: True WYSIWYG. Depending of the used Mozilla version the preview would reflect the real XUL capabilities of the used Mozilla. Relatively small amount of code for the editor.
Investigate Browser based on GtkMozembed widget (attached is a gtkembed based prototype)
Need support for Mozilla browser widget on Windows platforms - WOW - this bug has the working source attached for the mozilla-widget on windows !
Composer - SWT HTML Editor Widget - embedds Mozilla as editor control. Available for win/*nix/osx.IDE4Lazlo IBM stuff for lazlo, this may be a guide line on what is possible.
