Introduction
This article presents a digital clock written using C# .Net 3.5 and Windows Presentation Foundation (WPF), with a version supporting styling using the RibbonStyleHandler from the Ribbon Control Library (and hence allowing styling consistent with RibbonWindow applications).
Using the Code
This is VERY simple, to create a new clock window, make a new instance of DigitalClockWindow! To add a control to an existing window, use DigitalClockControl.
About the Code
The DigitalClock class is comprised of DigitalClockDots and DigitalClockElement. The DigitalClockDots class is a UIElement representing two dots to separate hours from minutes from seconds. DigitalClockElement represents the following states: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Hence the DigitalClock is a Grid of DigitalClockElement DigitalClockElement DigitalClockDots DigitalClockElement DigitalClockElement DigitalClockDots DigitalClockElement DigitalClockElement.
The DigitalClockControl and DigitalClockWindow classes contain a thread for updating the clock when AutoUpdate is set to true, otherwise the clock may be updated via the .CurrentTime property of DigitalClockControl.
DigitalClockControl contains three properties for styling, DigitBrush the Brush used to render the digits (0 to 9), DotBrush the Brush used to render the separating dots, and ClockBackground the background of the clock. DigitalClockDots contains a single property RenderBrush for setting the brush used to render the dots. DigitalClockElement contains a similar property RenderBrush for setting the brush used to render the graphic components. Furthermore it also contains a Value property for setting the value to display (in the range 0 to 9).
Ribbon Styled Clock
In version 1.0.0.1 RibbonClockControl and RibbonClockWindow have been added which inherit from DigitalClockControl and DigitalControlWindow respectively; they add automatic styling based on the RibbonStyleChanged event, and can be seen in use in the CIRIP project (a Computational Intelligent Railway Intervention Planner).
