NSView-based embedding on Mac OS X

[E KN]

Hi Petr,

Thank you so much for your explanation. Would be very grateful if you
could clarify one other thing though.

The SWT_AWT bridge API supports both embedding an AWT component inside
SWT as well as embedding an SWT component inside AWT. Looking at the
source code of the SWT_AWT java class and the swt_awt.c C code, it
would appear that only embedding an AWT component inside SWT is
supported in JDK7u40. But the reverse, embedding an SWT component
inside an AWT component does not appear to be supported (since the
native C code in awt_swt.c, called from the new_Shell function makes use of
the
legacy JAWT_MacOSXDrawingSurfaceInfo struct in jawt_md.h which was removed
in
Java 7).

Is this correct? Are there any plans to support this latter form of
embedding again? (I am asking because I am dependent on a third party
library which uses this same API as this latter form of embedding).

Thanks again,
Eli
