Mouse Event Handlers
The following standard event handlers of the CView class are involved in providing feedback.
*OnLButtonDown()
*OnLButtonUp()
*OnMouseMove()
*OnTimer()
If you override these functions in your view class derived from SRGraphView, call the base class function to preserve user interaction functionality.
NOTE >> The features described in this section are supported by all of the Objective Chart view classes. For brevity, the term ‘SRGraphView’ may be used to refer to any of these classes.
