Pyqt5 loop over class variables and change state/set values
问题
我有一个带有一定数量的类变量的类。这些变量是不同类型的，例如 QLineEdit/QCheckbox 等等。如何循环遍历类变量以设置变量值如下：
obj = FindObj()value = ['100', 'yes', 'False']i=0for variable in obj:if variable.__class__() == 'QLineEdit': # 不知道是否正确variable.setText(value[i])i=i+1elif variable.__class__() == 'QCheckBox':variable.setChecked(value[i])i=i+1import sysfrom PyQt5.QtWidgets import QApplication, QWidgetfrom PyQt5.QtGui import QIconclass FindObj():def __init__(self):super().__init__()self.l1 = QLineEdit()self.l2 = QLineEdit()self.l3 = QCheckBox()if __name__ == '__main__':app = QApplication(sys.argv)ex = FindObj()sys.exit(app.exec_())

I have a class with certain number of class variable. Variables are of different types e.g. QLineEdit/QCheckbox....etc. How can I loop over class variable to set a variable value as below:
obj = FindObj()value = ['100', 'yes', 'False']i=0for variable in obj:if variable.__class__() == 'QLineEdit': # Don't know if it's rightvariable.setText(value[i])i=i+1elif variable.__class__() == 'QCheckBox':variable.setChecked(value[i])i=i+1import sysfrom PyQt5.QtWidgets import QApplication, QWidgetfrom PyQt5.QtGui import QIconclass FindObj():def __init__(self):super().__init__()self.l1 = QLineEdit()self.l2 = QLineEdit()self.l3 = QCheckBox()if __name__ == '__main__':app = QApplication(sys.argv)ex = FindObj()sys.exit(app.exec_())

如果您也将变量放入一个列表中，您可以循环遍历这两个列表：
class FindObj():def __init__(self):self.l1 = QLineEdit()self.l2 = QLineEdit()self.l3 = QCheckBox()self.variables = [self.l1, self.l2, self.l3]
现在您可以循环遍历它们：
obj = FindObj()values = ['100', 'yes', 'False']for variable, value in zip(obj.variables, values):if variable.__class__.__name__ == 'QLineEdit':variable.setText(value)elif variable.__class__.__name__ == 'QCheckBox':variable.setChecked(value)
英文:
If you put your variables in a list as well, you can loop over both lists:
class FindObj():def __init__(self):self.l1 = QLineEdit()self.l2 = QLineEdit()self.l3 = QCheckBox()self.variables = [self.l1, self.l2, self.l3]
Now you can loop over them:
obj = FindObj()values = ['100', 'yes', 'False']for variable, value in zip(obj.variables, values):if variable.__class__.__name__ == 'QLineEdit':variable.setText(value)elif variable.__class__.__name__ == 'QCheckBox':variable.setChecked(value)
