View Geometry

A view is responsible for the drawing and event handling in a rectangular area of a window. In order to specify that rectangle of responsibility, you define its location as an origin point and size using a coordinate system. This chapter describes the coordinate system used by views, how a view's location and size is specified, and how the size of a view interacts with its content.
