无法显示消息对话框

Posted 2021-04-21

我有一个包含一些QPushButtons的类，每当我按下一个按钮时，我希望程序显示一条消息，说明已执行该操作。到目前为止，我已经尝试创建一个QMessageBox并在它下面的按钮函数中调用它，但它不起作用。我一直收到编译器错误。这是我的代码和我的堆栈跟踪。我无法弄清楚我做错了什么。

堆栈跟踪

line 270, in data_parsed_notification
    msgBox.information(self, 'Message', 'Data Has Been Parsed!', QMessageBox.StandardButtons)
TypeError: QMessageBox.information(QWidget, str, str, QMessageBox.StandardButtons buttons=QMessageBox.Ok, QMessageBox.StandardButton defaultButton=QMessageBox.NoButton): argument 1 has unexpected type 'Ui_MainWindow'

改为self.window

self.canonicalAddressesButton.clicked.connect(self.data_parsed_notification)
    window = QtWidgets
    def data_parsed_notification(self):
        msgBox = QtWidgets.QMessageBox()
        msgBox.information(self.window, 'Message', 'Data Has Been Parsed!', QMessageBox.StandardButtons)

答案

简短解决方案

def setupUi(self, MainWindow):
    self.mainwindow = MainWindow
    [...]

def data_parsed_notification(self):
    QtWidgets.QMessageBox.information(self.mainwindow, 'Message', 'Data Has Been Parsed!', QtWidgets.QMessageBox.Ok)

简短的解决方案可以解决您当前的问题，但我认为从长远来看，您将遇到更多相同类型的问题，因此即使它易于实现，我建议使用长解决方案，因为它将避免其他问题。

长解决方案：

生成Qt Designer的类不是小部件，它是用于填充小部件的类，并且因为information()的QMessageBox方法需要QWidget正在生成该类型的错误。

建议不要修改设计，也就是说，你应该保留设计，并创建另一个负责管理逻辑的.py文件，这样你就可以再次修改你的设计，而不必重新编写任何东西。

假设您已经恢复了设计和该文件，我们可以将其称为ui_mainwindow.py：

UI_main window.朋友

class Ui_MainWindow(object):
from PyQt5 import QtCore, QtWidgets

    # Main window setup
    def setupUi(self, MainWindow):
        [...]

    # Function that sets the text on all the UI Buttons
    def retranslateUi(self, MainWindow):
        [...]

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

然后创建另一个名为main.py的文件，我们将在其中创建窗口小部件并使用设计来填充它：

from PyQt5 import QtCore, QtWidgets
from reportViewerWindow import Ui_reportViewerWindow
from ui_mainwindow import Ui_MainWindow

class ReportViewerWindow(QtWidgets.QMainWindow, Ui_reportViewerWindow):
    def __init__(self, *args, **kwargs):
        QtWidgets.QMainWindow.__init__(self, *args, **kwargs)
        self.setupUi(self)

class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self, *args, **kwargs):
        QtWidgets.QMainWindow.__init__(self, *args, **kwargs)
        self.setupUi(self)

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    w = MainWindow()
    w.show()
    sys.exit(app.exec_())

并且在这个新类中实现了你的逻辑，上面是一个简短的总结，但接下来我将放置所有代码：
