Clock -Overview

Architectural relationships

The animation -of the clocks is performed by an animation DLL that plugs-in to the Window -Server. The key classes in this API are client-side animation classes, derived -from the animation client-side class RAnim.

Description

The API has three key concepts: clock -base classes, analogue clock, and digital clock.

Clock base classes

A -number of base classes provide shared functionality for the clocks, including -basic display control, and time setting. They derive ultimately from RAnim, -and are, in inheritance order, RAnimWithUtils, RTimeDevice, -and RClock.

Analogue clock

Derived -from RClock, the class RAnalogClock provides -an analogue clock with configurable color, size, position, and number of hands.

How -a hand is drawn is specified by a TAnalogDisplayHand object. -The settings for displaying an AM/PM indicator is provided by SAnalogDisplayAmPm.

Digital -clock

Derived from RClock, the class RDigitalClock provides -a digital clock with configurable color, size, position, and font. What time -information is displayed is configured through one or more TDigitalDisplayTextSection objects.
