Qt-based mobile application GUI style for smart phone operating system

On the one hand, smart phones are becoming an important means for personal and business applications, such as voice, data, e-mail, and Internet access. And on the other hand, the most current operating system for smart phones has greatly extended the application fields in the future. The current popular smart phone operating systems are quite different and there is not standard development platform for smart phone applications as yet, which cause the develop language selection confusion. Qt, as a cross-platform application and UI framework, has a significant development in recent years. Making use of the flexibilities of Qt-based applications, two algorithms, CSS style sheets and subclassing Qt style class, are described in this paper to solve this problem. Three examples are also illustrated to show the capabilities and advantages offered by this flow.
