Question

我有3个文件：Gui.py，IPG_weld.py，Reading.py

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
    from Ipg_weld import Ui_IPG_weld


    class Test(Ui_IPG_weld):
    def __init__(self):

        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()

所以我当前要做的就是将在IPG_weld.py（Read_Button和Save_Button）中创建的两个按钮连接到我的事件：当单击Read_Button时，应该执行reading.py中的reading（），其中将填充数组Setup_weld_num，并且 PlainTextEdit_18到PlainTextEdit_28接收来自setup_weld_num数组的元素。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

将输出数转换为Plain_TextEdit_18 - plainTextEdit_25，这样用户就可以在Gui的文本框中看到它们。

怎么做得好？

UPD：你可以看到我添加了：

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

并尝试将 first_edit 数组的第一个元素转移到 PlainTextEdit_18 ：

self.plainTextEdit_18.setPlainText(first_edit[1])

但它不起作用，因为对于retranslate_UI函数，数组 first_edit 不可见。

Answer 1

作为对Ipg_weld.py个州顶部的评论，将任何代码添加到此文件是没用的，因为它将由Qt UI编译器重写。考虑在Test中向您的班级Gui.py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。请注意，QPushButton信号clicked（大小写很重要），信号方法connect（more about signals and slots in pyqt）。

在您的示例行first_text=self.Read_Button.Clicked.Connect(reading())实际调用 reading（请注意括号），但在连接信号和插槽时，您必须提供可调用的connect方法（考虑它就像你指定一个函数名而不是调用它）。

总结一下，添加与课程<{>> __init__的连接：

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，您应该在点击按钮时看到file_values打印。

PyQT5中的信号/插槽无法正常工作，因为数组对于函数不可见
