我有 3 个文件：Gui.py、IPG_weld.py Reading.py
Gui.py 是：

Ipg_Weld.py是：

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()
因此，我目前要做的是将两个在IPG_weld.py(Read_Button和Save_Button(中创建的按钮连接到我的事件： 当Read_Button单击时，应该在填充数组Setup_weld_num的地方执行 reading.py 中的 reading((，并且 PlainTextEdit_18 PlainTextEdit_28从数组中接收setup_weld_num元素。换句话说，我想从文件中读取：
&ACCESS RVP1
&REL 3
&PARAM DISKPATH = KRC:R1Programnew
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
并将输出数量转换为Plain_TextEdit_18 - plainTextEdit_25，以便用户能够在 Gui 的文本框中看到它们。
如何正确操作？
UPD：如你所见，我补充说：
first_text=self.Read_Button.Clicked.Connect(reading())
并尝试将数组的第一个元素first_edit传输到PlainTextEdit_18：
self.plainTextEdit_18.setPlainText(first_edit[1])
但它不起作用，因为数组first_edit对于retranslate_UI函数不可见。
正如Ipg_weld.py状态顶部的注释，向该文件添加任何代码是没有用的，因为它将被Qt UI编译器重写。考虑在Gui.py中将单击处理程序函数添加到类Test中。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_())
然后你有处理程序功能，连接按钮信号到它。请注意，QPushButton有信号点击(案例(，信号有方法connect(更多关于 pyqt 中的信号和插槽(。
在您的示例行中first_text=self.Read_Button.Clicked.Connect(reading())实际上调用reading(请注意括号(，但在连接信号和插槽时，您必须提供可调用connect方法(将其视为指定函数名称而不是调用它(。
总结一下，为您的班级测试__init__添加连接：
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，您应该在单击按钮时看到file_values打印。
