What is difference between OnPaint and OnDraw?

[Hemant kulkarni]

Hi, I am developing a application in which I need to draw the some text and graphics on the view. I can do this in OnPaint as well as in OnDraw. But when one should use OnPaing and when OnDraw()? What is difference between OnPaint and OnDraw? Regards, Hemant Kulkarni.

OnDraw() is ultimately called by OnPaint(), as you can find inside MFC sources:

void CView::OnPaint()
{
// standard paint routine
CPaintDC dc(this);
OnPrepareDC(&dc);
OnDraw(&dc);
}

There you can also see what happens inside OnPrepare(). :)

In the structure of MFC,OnPaint is the member function of Cwnd,OnDraw is the member function of CView Nothend

OnPaint() belongs to CWnd and handles the WM_PAINT message, while OnDraw() belongs to CView and is virtual.
