[platform-swt-dev] Purpose of THEME_BACKGROUND

[Eric Williams <ericwill@xxxxxxxxxx>]

Hello,

I see in Widget.java we have a flag called "THEME_BACKGROUND". It seems 
to be called fairly often in the createHandle() and checkBackground() 
methods.

My question: what does this do? What is the purpose of this flag? How 
does it differ from PARENT_BACKGROUND?

AFAIK, SWT has no notion of themes, so I am curious as to the use case 
of this flag.

Thanks,
