Pyside6加载QMessageBox时报错

Question

ui转换为py文件后，在进行初始化没有问题，但是加载QMessageBox时报错。

from PySide6.QtWidgets import QApplication,QMessageBox,QMainWindow
from ui.patinfo_search import *
import sys


class UI(QMainWindow,Ui_Form):
    def __init__(self,parent = None):
        super(UI,self).__init__(parent)
        # 子类继承了父类的所有属性和方法，父类属性自然会用父类方法来进行初始化
        self.ui = Ui_Form() # 来自 patinfo_search.py 中的类。
        self.ui.setupUi(self)
        self.ui.button1.clicked.connect(self.yahoo)
        self.ui.button2.clicked.connect(self.copy)

    def yahoo(self):
        print('button1 was be knocked')
        QMessageBox.about(self.ui,'反馈结果','hello hello hello')

    def copy(self):
        print('button1 was be knocked')
        info = self.ui.textedit1.toPlainText()
        QMessageBox.about(self.ui,'复制结果',f'{info}')

if __name__ == '__main__':
    app = QApplication(sys.argv)
    uiui = UI()
    uiui.show()
    sys.exit(app.exec_())

py文件

Answer 1

这可能是因为您在初始化QMessageBox时使用了不正确的参数。请确保在初始化QMessageBox时传递正确的参数，例如：QMessageBox.about(self.ui,'反馈结果','hello hello hello', QMessageBox.Yes | QMessageBox.No)这将使QMessageBox显示“是”或“否”选项，而不是默认的“确定”和“取消”选项
