Provides the graphical display of digital and analogue clocks. The clocks are animated to change with system time.
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.
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.
