[platform-swt-dev] Using UpdateLayeredWindow from SWT

[Scott Kovatch <skovatch@xxxxxxxxx>]

Hey,

Does anyone on this list have experience using UpdateLayeredWindow  
from within the SWT? I see it's defined in OS.java and in the DLL but  
no matter what I do the call always fails (returns false) and  
GetLastError is always 0. And, nothing updates on the screen.

I'm using this to implement a non-rectangular splash window. I know  
about Snippet219, but that doesn't allow for images of varying alpha,  
particularly at the edges. With the image I am using, I end up with a  
band around the image.

I still need to check with VC to ensure that the Win32 call is  
actually being invoked, but I wanted to check here if there's  
something odd about the generated code  because nothing within the SWT  
uses it.
