public interface IVsTextLayerEvents

NameDescription
System_CAPS_pubmethodOnMappingChange()

Fires to notify client to convert all of its local coordinates to base buffer coordinates.

System_CAPS_pubmethodOnMappingChangeComplete()

Fires to notify client to convert to the new local coordinates.

Sizing the window changes the word-wrap layer's mapping. The view synchronizes these events to maintain the selection. A client will generally convert all of its local coordinates to base buffer coordinates in OnMappingChange then convert to the new local coordinates in OnMappingChangeComplete. IVsTextLayerEvents are purely changes in coordinate mapping. If there is a change in the data, the layer should fire OnChangeLineText.
