Thank you very much for your timely response, I am able to use the drawing functions on layer. But still I am faced with one more problem. I have enabled the mouse for this layer and when I roll the mouse over the drawing it vanishes. Can you please advise what to do to make the drawing permanent on the surface? Your response will be highly appreciated.

If you want to use the windowing system, you shouldn't touch the layer's surface directly, but create windows and draw to their surfaces. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-dev mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
