Data model change notification flags.

Enumerator
CF_CALIB

◆ GetBoundingBox()

virtual i2d::CRect iview::IShape::GetBoundingBox ( ) const

pure virtual

Return bounding box in client window coordinates.

You can store this bounding box for optimization, because about every change of transformation you will be informed by calling OnDisplayChanged(int) method.

Implemented in iview::CShapeBase.
