RichUl : A new U1 component library based on J2ME

With the popularity of mobile phone, the function of the mobile phone has extended from communication tool to other areas, such as amusement, game, Web browsing, and so on. Most of the mobile manufactures have provided some toolkits in their products for developing such kinds of tools. However, different toolkits provided by different mobile phone manufacturers are quite different, mainly on screen size, screen color, way of key-press responsing and unicode character displaying, etc. One must develop the software for particular kind of mobile phones, and it is not easy to transplant the software from one kind of mobile phones to another kind, which bothers the developers quite well. To solve above problems, we have developed a wireless component library, RichUI. By using RichUI, developers can only concentrate on the development of business function without considering the details of different toolkit implementations, and the software developed based on RichUI can be used in different kinds of mobile phones.
