Implements

OnChangeScrollInfo(IVsTextView, Int32, Int32, Int32, Int32, Int32)

Remarks

This method is called when the scroll bar information changes, typically due to the associated source file being changed. If your language service needs to adapt to a changing scroll view then you must derive a class from the ViewFilter class and override this method.

This method is an implementation of the OnChangeScrollInfo method on the IVsTextViewEvents interface.

The base method does nothing.
