An IVsHiddenRegion object representing the hidden region that has changed.

evt: HIDDEN_REGION_EVENT

Remarks

This method is called whenever a hidden region is changed. This does not include changes made to the state of the hidden region.

This is an implementation of IVsHiddenTextClient's OnHiddenRegionChange method.

The base method does nothing.
