信号/在PyQT5槽不工作，因为阵列不是功能

可见我有3个文件：Gui.py，IPG_weld.py，Reading.py信号/在PyQT5槽不工作，因为阵列不是功能

Gui.py是：

import sys 
    from PyQt5 import QtCore, QtGui, QtWidgets 
    from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QMainWindow 
    from PyQt5.QtGui import QIcon 
    from PyQt5 import QtGui

    class Test(Ui_IPG_weld):

     super().__init__() 
     self.widget = QMainWindow() 
     self.setupUi(self.widget) 
     ... 
     self.widget.show() 

    if __name__ == '__main__': 
    app = QApplication(sys.argv) 
    main = Test() 
    sys.exit(app.exec_())

Ipg_Weld.py是：

     self.label_19.setText(_translate("IPG_weld", "Текущее ")) 
     self.label_20.setText(_translate("IPG_weld", "Новое"))

而且Reading.py是：

import sys 
import os 
import re 
import re 
def reading(): 
    with open ('Setup_Weld.src') as f: 
     stripped=[row.strip() for row in f] 
     setup_weld_num = [re.search(r'\[(.*?)\]',i).group(1) for i in stripped if re.search(r'\[(.*?)\]',i)] 
     print(setup_weld_num) 

reading()

所以我想要做的是将两个按钮（IPG_weld.py（Read_Button和Save_Button）中创建的两个按钮）连接到我的事件中：当Read_Button单击时，reading.py中的reading（）应该在数组Setup_weld_num将被填充，并且PlainTextEdit_18到PlainTextEdit_28从setup_weld_num数组接收元素。换句话说，我想从文件中读取：

&ACCESS RVP1 
&REL 3 
&PARAM DISKPATH = KRC:\R1\Program\new 
DEF SETUP_WELD() 
;call LASER_EN(); 

$out[27]=false; START=OFF 
$out[26]=false; STROBE=OFF 
$out[25]=false; SELECT 8=OFF 
$out[24]=false; SELECT 7 =OFF 
$out[23]=false; SELECT 6 =OFF 
$out[22]=false; SELECT 5 =OFF 
$out[21]=false; SELECT 4 =OFF 
$out[20]=false; SELECT 3 =OFF 
$out[19]=false; SELECT 2 =OFF 
$out[18]=false; SELECT 1 =OFF 
$out[17]=false; SELECT 0 =OFF 
$out[28]=true; ENABLE=ON 

END

和翻译的输出，以Plain_TextEdit_18号 - plainTextEdit_25，因此用户将能够看到他们在桂中的文本框中。

如何正确地做到这一点？

UPD：你可以看到我说：

first_text=self.Read_Button.Clicked.Connect(reading())

，并试图first_edit的第1个要素转移数组PlainTextEdit_18：

self.plainTextEdit_18.setPlainText(first_edit[1])

但其不工作，因为数组第一_edit对于retranslate_UI函数不可见。

仅供参考：https：//stackoverflow.com/help/mcve –

作为关于Ipg_weld.py状态顶部的注释，将任何代码添加到此文件是没用的，因为它将被Qt UI编译器重写。考虑在Gui.py中为您的课程Test添加点击处理函数。例如：

import sys 
from PyQt5 import QtCore, QtGui, QtWidgets 
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QMainWindow 
from PyQt5.QtGui import QIcon 
from PyQt5 import QtGui 
from Ipg_weld import Ui_IPG_weld 
import Reading 


class Test(Ui_IPG_weld): 
    def __init__(self): 
     super().__init__() 
     self.widget = QMainWindow() 
     self.setupUi(self.widget) 
     # ... 
     self.widget.show() 

    def read_file(self): 
     file_values = Reading.reading() 
     print("Got values:", file_values) 
     # change this accordingly 
     self.plainTextEdit.setPlainText(file_values[0]) 
     self.plainTextEdit_2.setPlainText(file_values[1]) 
     # ... 


if __name__ == '__main__': 
    app = QApplication(sys.argv) 
    main = Test() 
    sys.exit(app.exec_())

然后你有处理函数，连接按钮信号它。请注意0有信号clicked（案件事宜）和信号有方法connect（more about signals and slots in pyqt）。

在你的榜样线first_text=self.Read_Button.Clicked.Connect(reading())实际上调用reading（注意括号），但同时连接信号和槽，你必须提供一个可以调用到connect方法（考虑像你指定的函数的名称，而不是调用它）。

总结说起来，增加连接到你的的__init__类测试：

class Test(Ui_IPG_weld): def __init__(self): super().__init__() self.widget = QMainWindow() self.setupUi(self.widget) # ... # connecting button. Note that you should not call # self.read_file here. self.Read_Button.clicked.connect(self.read_file) self.widget.show()

现在你应该看到file_values打印的同时单击按钮。
