 pyqt4轉ui文件爲py：

在cmd控制檯下,進入uic目錄:

cd C:\Cocos\tools\Python27\Lib\site-packages\PyQt4\uic

輸入命令

python pyuic.py ui文件路徑 -o py文件路徑

由於Qt生成的代碼得要有其它東西調用才能出來界面 
所以若是想運行出界面還需另外添加以下代碼

if __name__ == "__main__":   
    app = QtGui.QApplication(sys.argv)   
    myapp = MyForm()   #MyForm是本身的窗體類名
    myapp.show()   
    sys.exit(app.exec_())  

 在類中添加初始化：

class Ui_Dialog(QtGui.QDialog):

    def __init__(self):
        super(Ui_Dialog, self).__init__()
        self.setupUi(self)

注意，自動生成的類可能須要繼承（QtGui.QDialog）

 

爲了實現界面與底層功能代碼分離建議另外新建一個文件用來編寫底層功能代碼，如新建一個main.py:

from PyQt4 import QtGui

import sys

from GammaSpecPro3 import Ui_MainWindow

#​GammaSpecPro3爲***.ui轉換的py文件名，也就至關於模塊。

#​Ui_MainWindow爲GammaSpecPro3界面的類，打開該py文件便可看到

​

​class MyWindow(QtGui.QMainWindow):

    def __init__(self):

        super(MyWindow, self).__init__()

        self.ui = Ui_MainWindow() #這裏須要注意self.ui已經將Ui_MainWindow類實例 #化，所以繼承了該類的全部屬性，後面更改設置屬性都用self.ui「冠名」

        self.ui.setupUi(self)

=======================我是註釋========================

這個類的下面就能夠編寫（def）本身的函數，如按鈕的功能等

def。。。

​=======================註釋完畢========================

  

if __name__ == "__main__":

      app = QtGui.QApplication(sys.argv)

    w = MyWindow()

    w.show()

    sys.exit(app.exec_())

以後直接運行main.py
