• iBar
  Type: System.Int32
  [in] The scroll bar ID: SB_VERT for the vertical bar and SB_HORZ for the horizontal bar.

• iMinUnit
  Type: System.Int32
  [in] The new minimum value for the scroll bar (typically in lines).

• iMaxUnits
  Type: System.Int32
  [in] The new maximum value for the scroll bar (typically in lines).

• iVisibleUnits
  Type: System.Int32
  [in] The new value representing the number of visible lines in the scroll bar (affects the size of the scroll thumb).

• iFirstVisibleUnit
  Type: System.Int32
  [in] The new value for the first visible line in the scroll bar (affects the position of the scroll thumb).

Implements

IVsTextViewEvents.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.
