By default the Browser control embeds a natively-available
browser renderer, so these capabilities are determined by what the user
has installed (eg.- their IE or Safari version, etc.). For a list
of the supported native browser renderers see http://www.eclipse.org/swt/faq.php#browserplatforms
.
If you want to guarantee a consistent set of capabilities
then you can ship a XULRunner (Mozilla's renderer) with your app and create
your Browser instances with style SWT.MOZILLA. For info on this see:
