how to subclass QLineEdit to have index

Question

I need to subclass a PyQt5 QLineEdit so that it has an index, such that I could access it by:

    stringvariable = LineEdit(0).text()
    stringvariable = LineEdit(1).text()
    stringvariable = LineEdit(2).text()

Is this possible?

Answer 1

Why don't you make a list of your LineEdits?

mylist = [QLineEdit(), QLineEdit(), QLineEdit()]
    
index = 0
string = mylist[index].text()
print(string)

Or, if you really need to make a subclass

class MyLineEdit(QLineEdit):
    all_instances = {}
    def __init__(self, index, *args, **kwargs):
        super(MyLineEdit, self).__init__(*args, **kwargs)  # call to superclass
        MyLineEdit.all_instances[index] = self  # add this instance to MyLineEdit.all_instances
    
def LineEdit(index):
    return MyLineEdit.all_instances[index]

To use it, you can simply do:

# Make an instance
edit = MyLineEdit(123)

string = LineEdit(123).text()
# which is equivalent to using
string = edit.text()
