I have to fill transparent circles.

On the one hand the class DirectGraphics does not have any method for drawing arcs. On the other hand, their is no possibility to draw transparent shapes with the Graphics class methods.
I tried combining both.
Using setARGBColor from DirectGraphics and drawing with fillArc from Graphics. But this does not work. The arcs are filled non-transparent then.

What do I have to do?

I am using Series_60_MIDP_SDK_for_SYMBIAN_OS_v_1_0

Thanks for your help.
