	IVsTextView view


Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextView

[in] An IVsTextView object representing the view that has received the focus.



If your language service needs to respond to a view gaining focus, then you must derive a class from the ViewFilter class and override this method.

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

The base method calls the OnSetFocus method on the CodeWindowManager object passed to the ViewFilter class constructor (which means you can override the CodeWindowManager class's version of the method if you otherwise do not need to override any method in the ViewFilter class). The base method then calls the OnActiveViewChanged method.
