中文摘要: 详细介绍了基于嵌入式Linux和Qtopia的矩阵键盘输入实现方法。通过重载Qt的事件过滤器，结合信号和槽机制，利用两级状态处理及有效输入的界定，来简化输入过程， 减少按键次数，提高输入效率。同时利用Qtopia的图形显示，使输入界面清晰，更适用于嵌入式终端设备。
Abstract:This paper introduces an input method in detail based on embedded Linux and Qtopia matrix keyboard. By reimplementing the Qt event filter, combined with signal and slot mechanism to deal with the use of two-tier status, it is possible to use the definition of the effective input to simplify the input process, reduce the number of pressing button, and enhance the efficiency of input. At the same time, with the use of Qtopia graphical display, the input interface is clearer and more applicable to the embedded device.
