ExGsCompositeClientDevice::update Method

Syntax
C++
virtual void update(OdGsDCRect* pUpdatedRect);
Description

This is our main change for support composition. We need separate partial update onto two steps, because invalidation data after updateExtents must be propagated into all linked devices. After that updateScreen could be called for all dependent devices in same context.
