Member Enumeration Documentation

The port's focus state

virtual void IViewPort::BeginFocus ( )

pure virtual

Called when this port becomes the target of graphic operations. This is called by the raster port arbitrator in its BeginPortFocus implementation.

virtual void IViewPort::EndFocus ( )

pure virtual

Called when this port is torn down by the raster port arbitrator. This is called by the raster port arbitrator in its EndPortFocus implementation.

virtual FocusState IViewPort::GetFocusState ( ) const

pure virtual

Returns the port's focus state

virtual IPMUnknown* IViewPort::GetOwner ( )

pure virtual

Gets the port's owner. This may be any interface

virtual void IViewPort::ResumeFocus ( )

pure virtual

Called when this port is suspended and is once again about to receive the focus

virtual void IViewPort::SetOwner ( IPMUnknown * owner )

pure virtual

Sets the port's owner. This may be any interface

Note: Internal implementations do not take ownership of owner and will not call AddRef or Release on it

Parameters

owner IN The port's owner

virtual void IViewPort::SuspendFocus ( )

pure virtual

Called when this port has the focus and another port is about to receive the focus
