Question

我使用pyqt4制作了一个应用程序。

它有七个按钮。六个是完全相同的，但只是最后一个有效。另一个是退出按钮

每个按钮运行一个脚本，用于转换某个ESRI SHP文件中的csv文件。

错误在哪里？

import sys
from archivo import *

import datetime
import os
import pandas as pd
import shapefile as shp 
import csv  
import tkinter.filedialog

Answer 1

也许这有效：

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...并不代表更多的内容;它意味着你的其他类方法。

__init__是类的python构造函数。它将在创建类时执行一次。你在这里做的是多次声明__init__，这样你就可以有效地覆盖以前的__init__。只执行最后一个，这将是正在工作的按钮。

哦，请看一下this python样式指南，因为你的（类）命名很糟糕。

Answer 2

每个班级只能有一个__init__。每次解释器看到__init__时，它都会用新的定义替换定义，即。只有最后__init__会做某事

PyQt4按钮但只有一个工作。为什么？
