本文介绍了如何使用PyQt4和Qt Designer将.ui界面文件转换为.py代码，并详细说明了转换后的.py文件如何添加额外代码以实现可视化运行。包括两种方法：直接在.py文件末尾添加代码或创建新的Main.py文件。对于Dialog窗口，还需要实现accept()和reject()函数。

1.转换ui为py

.py文件是这样生成的：

在cmd控制台下,进入uic目录:

cd C:\Users\MVTECH\Anaconda3\Lib\site-packages\PyQt4\uic

输入命令：

python pyuic.py "ui文件路径" -o "py文件路径"

完成以上操作以后会生成.py文件，以下为示例代码：

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'C:\experiment\Kezhihuang\ECGMachineLearning\ECGMachineLearning.ui'
#
# Created by: PyQt4 UI code generator 4.11.4
#
