# 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。 # # 2015-10-23 晴 深圳 南山平山村 曾剑锋 \\\\\\\\\\\\\-*- 目录 -*-//////////// | 一、cat main.pyw | 二、cat HardwareDialog.pyw | 三、cat Ui_HardwareManager.pyw | 四、cat hardwaremanager.ui | 五、cat autorun.bat | 六、cat readme.txt ------------------------------------ 一、cat main.pyw #coding=utf-8 # 参考文章： # 1. pyqt 使用 Qt Designer 设计的ui文件 # http://blog.csdn.net/lainegates/article/details/8656145 # 2.

六、cat readme.txt 一、文件说明： 1. managerFile目录主要是程序生成的信息文件，不要去动它； 2. pyhon2.7目录包含了python2.7、pyqt4的安装文件； 3. autorun.bat是windows的批处理文件，双击运行，会自动main.pyw文件; 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： 1. 可以通过双击main.pyw文件运行； 2. 可以通过双击autorun.bat文件运行。
