• PyQt4 HardwareManager


    #                            PyQt4 HardwareManager
    # 声明:
    #     本软件主要是由于朋友说想要一个产品缺陷记录软件,主要用于记录产品缺陷,
    # 通过产品序列号进行插入、查询,本来想用VC++ 6.0做,但是每次打开开发环境就
    # 奔溃了,所以只能换一个开发环境,于是尝试用PyQt4进行原型开发,在开发过程中
    # 发现,这确实是一个很好的思路,该软件可以换一种思路用于其他环境下,但就
    # 目前而已,这仅仅是一个原型。

            4. 所有的.pyw文件是python程序文件;
            5. hardwaremanager.ui文件是qt Designer生成的文件,通过pyuic4.bat将ui文件转成ui_hardwaremanager.pyw;
            6. logo.ico是程序的ico文件。
        二、程序运行说明:
