Hi,

I see that in http://www.eclipse.org/rap/noteworthy/1.3/news_M2.php you have said that Control#setParent()has been added to the API. I am using 1.5M2 and when I checked the source code of Control#setParent()it contains no implementation. Could you please let me know the reason for not implementing setParent() method? We use the same code for RCP on windows which uses org.eclipse.swt.win32.win32.<version>.jar and it has a proper implementation of Control#setParent().

Control#setParent() is an optional operation. The JavaDoc for says "...
if the underlying operating system supports this feature".
It is a considerable effort to implement and we decided to use the given
resources for other features.

For compatibility with SWT, we provided an empty implementation. You can
use Control#isReparentable() to check whether a control can be reparented.

If you *really* have a need for reparentable widgets, you may open an
enhancement request. As it is not on the plan for 1.5, I doubt that it
will be implemented in the near future.
