I got the hunch from Netscape's progress control in the status bar. Since most of the complexity is hidden in the implementation, using this is as easy as using a normal progress bar. This control is not derived from CProgressBarctrl but from CStatic to ensure simplicity and efficiency. An imitation of Netscape status bar as well as a dialog based demo like that of CGradientProgress is included in the sample zip file. If this control is used in a dialog box, simply put a CStatic Place holder in the dialog and subclass it to CEZSnakeCtrl. Now you can customize the look & feel of the control. Various options available are:
//Get & Set The Maximum value of the progress control //0 is assumed as the minimum. int GetMax(); void SetMax(int nMax); //Get & Set the size of the snake int GetSize(); void SetSize(int nSize); //Get & Set the the Steps ->unit increment int GetStep(); void SetStep(int nStep); //Get The Head Position int GetPos(); //Get The tail position int GetTail(); //Get the direction of the snake BOOL IsReverse(); //Get & Set the Gradient begin & end colors COLORREF GetGradientEndColor(); COLORREF GetGradientStartColor(); void SetGradientFill(COLORREF clrStart,COLORREF clrEnd); //Get & Set Background color COLORREF GetBkColor(); void SetBkColor(COLORREF clrFG); //Operations<>BR int StepIt();//Move the snake. void ResetProgress();//reset the snake
I think the demo project can do rest of the explaining.
