If its just a simple bitmap animation, with a low framerate (say, below 15 fps or so), just letting a timer update the state (increase frame number) and call DrawNow() should be enough.

CPeriodic is a very easy-to-use animation timer.

Create a static callback:

TInt CMyClass::MyTimerCB(TAny* aArg)
{
 CMyClass* self = (CMyClass*)aArg; // to be able to access members, since statics functions can't use "this" ptr

  return ETrue; //Return false to stop timer.
}

and create and start a CPeriodic member:

 iTimer = CPeriodic::NewL(CActive::EPriorityStandard);
 iTimer->Start(KFrameIntervalInMicroSeconds, KFrameIntervalInMicroSeconds, TCallBack(MyTimerCB, this));

Hi,

I would like to implement bitmap animtion...i went through the various Classes(CBitmapAnimClientData) present in symbian to achieve this....But in my case my application is a single window application....so i felt that these classes might create a new window for just the animation(which i dont prefer)....
I would like to know three things:
