Inside Macintosh: QuickDraw GX Objects /

Chapter 7 - View-Related Objects / View-Related Objects Reference

View Port Functions

This section describes the QuickDraw GX functions you use with view port objects. Using the functions described here, you can

• create and manipulate view port objects
• manipulate view port object properties
• retrieve the view devices that intersect a view port
• retrieve the view ports that intersect a shape
• measure a shape in a view port

To associate a view port object directly with a QuickDraw GX transform object, use
the GXGetTransformViewPorts and GXSetTransformViewPorts functions. To associate a view port object indirectly with a QuickDraw GX shape object, use the GXGetShapeViewPorts and GXSetShapeViewPorts functions. All four functions are described in the chapter "Transform Objects" in this book.
