Question

当我通过PyQT按下按钮时，我想要一个脚本运行。这是我创建的按钮的一个例子

<Property name="ConnectionName">cn=wso2admin,ou=Users,dc=prc,dc=com</Property>

这是我想要运行的脚本然后按下按钮。这是一个自动测试，可以打开浏览器并执行某些操作。

import sys
from PyQt5.QtWidgets import QMainWindow, QPushButton, QApplication

class AutoTestWindow(QMainWindow):

    def __init__(self):
        super().__init__()

        self.initUI()


    def initUI(self):

        btn1 = QPushButton("Test № 1 ", self)
        btn1.move(30, 50)

        btn2 = QPushButton("Test № 2", self)
        btn2.move(150, 50)

        btn1.clicked.connect(self.buttonClicked)
        btn2.clicked.connect(self.buttonClicked)

        self.statusBar()

        self.setGeometry(300, 300, 290, 150)
        self.setWindowTitle('Запуск тестов')
        self.show()


    def buttonClicked(self):

        sender = self.sender()
        self.statusBar().showMessage(sender.text() + ' test started')


if __name__ == '__main__':

    app = QApplication(sys.argv)
    ex = AutoTestWindow()
    sys.exit(app.exec_())

我应该做些什么来实现它？我按下按钮时试图调用一个函数，但它没有工作

试一试：

from PyQt5.QtWidgets import QMainWindow, QPushButton, QApplication, QStatusBar

class AutoTestWindow(QMainWindow):

    def __init__(self):
        super().__init__()

        self.driver = None                      # +++         
        self.query  = "Тензор"                  # +++

        self.initUI()


    def initUI(self):

        btn1 = QPushButton("Test № 1 ", self)
        btn1.move(30, 50)

        btn2 = QPushButton("Test № 2", self)
        btn2.move(150, 50)

        #btn1.clicked.connect(self.buttonClicked)                                     # ---
        #btn2.clicked.connect(self.buttonClicked)                                     # ---
        btn1.clicked.connect(self.init_driver)                                        # +++
        btn2.clicked.connect(lambda checked : self.findelem(self.driver, self.query)) # +++

        self.statusBar().showMessage('Запуск тестов', 5000)

        self.setGeometry(300, 300, 290, 150)
        self.setWindowTitle('Запуск тестов')
        self.show()

    # ---
    #def buttonClicked(self):
    #    sender = self.sender()
    #    self.statusBar().showMessage(sender.text() + ' test started')

    # +++
    def init_driver(self):
        self.statusBar().showMessage('Test № 1  test started')
        #driver           = webdriver.Chrome("/Users/alexeynikitin/Desktop/chromedriver")
        self.driver     = webdriver.Chrome()
        self.driver.wait = WebDriverWait(self.driver, 10)
        #return self.driver

    # +++
    def findelem(self, driver, query):
        print("\ndriver=`{}`, \nquery=`{}`\n".format(driver, query))
        self.statusBar().showMessage('Test № 2  test started')
        if driver is not None:  
            driver.get("https://www.yandex.ru/")
            try:
                box = driver.wait.until(ec.presence_of_element_located(
                                        (By.ID, "text")))
                button = driver.wait.until(ec.visibility_of_element_located(
                                           (By.CLASS_NAME, "search2__button")))
                box.send_keys(query)

                try:
                    button.click()   
                except ElementNotVisibleException:
                    button = driver.wait.until(ec.visibility_of_element_located(
                                               (By.CLASS_NAME, "search2__button")))

            except TimeoutException:
                print("ничего не нашел на https://www.yandex.ru/")

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex  = AutoTestWindow()
    sys.exit(app.exec_())

如果我正确理解了您的问题，那么在初始化课程时（或在您的initUI方法中）将clickbutton事件连接到正确的函数就足够了：

def __init__(self):
    super().__init__()
    self.initUI()

    btn1.clicked.connect(init_driver)
    btn2.clicked.connect(lambda checked :findelem(value1, value2))

我更正了第二个绑定为@eyllanesc建议

调用python脚本的一种简单方法是使用os 假设您的脚本与应用程序位于同一文件夹中，则需要添加import os，然后在函数os.system('yourscriptname.py')中调用buttonClicked。

PyQT5 + Python。按下按钮时如何调用脚本？
