Hi Aliso, I already answered you in the forum, concerning your code, but here's the fastest way to add a shadow effect: MyShape.EffectAddClass(TdtpShadowEffect); MyShape must be a TdtpEffectShape descendant. For some users the edit demo is indeed a bit complicated with that many forms and frames, so a better place to start is possibly the speechbubbles demo, or the multi demo.
