PyQt4按鈕，但只有一個作品。爲什麼？

Question

我已經使用pyqt4做了一個應用程序。

它有七個按鈕。六個完全一樣，但最後一個工作。 另一個是退出按鈕

每個按鈕都運行一個腳本，用於在某些ESRI SHP文件中轉換csv文件。

錯誤在哪裏？

Answer 1

也許這個作品：

class importo_script_py (QtGui.QDialog): 
    def __init__(self, parent=None): 
     QtGui.QWidget.__init__(self, parent) 
     self.ui = Ui_Dialog() 
     self.ui.setupUi(self) 
     QtCore.QObject.connect(self.ui.pushButtonxxxx01, QtCore.SIGNAL ('clicked()') ,self.xxxx01) 
     QtCore.QObject.connect(self.ui.pushButtonxxxx02, QtCore.SIGNAL ('clicked()') ,self.xxxx02) 
     QtCore.QObject.connect(self.ui.pushButtonxxxx03, QtCore.SIGNAL ('clicked()') ,self.xxxx03) 
     QtCore.QObject.connect(self.ui.pushButtonT3, QtCore.SIGNAL ('clicked()') ,self.boyaT3) 
     QtCore.QObject.connect(self.ui.pushButtonTOSCA12, QtCore.SIGNAL ('clicked()') ,self.boyaTOSCA12) 
     QtCore.QObject.connect(self.ui.pushButtonT14, QtCore.SIGNAL ('clicked()') 

    etc.... 

哦，etc...並不意味着更多的inits;它意味着你的其他類的方法。

__init__是一個類的python構造函數。它將在創建類時執行一次。你在這裏做的是多次聲明__init__，所以你實際上覆蓋了你以前的__init__的。只有最後一個被執行，這將是正在工作的按鈕。

哦，請看this Python風格指南，因爲你的（類）命名是可怕的。

Answer 2

每個班只能有一個__init__。每當口譯人員看到一個__init__它正在用新的定義替換定義，即。只有最後的__init__會做點什麼
