Passing list to class init, pyQt

robbiecooper

Hi All

I'm new to Python and pyQt. I've got a class for a QDialog, and am passing a list of strings to this class in the init;

class Remove_Source(QtWidgets.QDialog, Ui_R_Source):
    def __init__(self, items=None):
        super(Remove_Source , self).__init__()
        self.ui = Ui_R_Source()
        self.ui.setupUi(self)
        self.setWindowTitle("Remove Source Folders")
        self.items = items or []
        for i in range(self.items.count()):
            self.ui.keep_window.addItem(self.items(i))
        self.exec()

The list is inaccessible within the class. Anyone know what I'm doing wrong? Thanks

@robbiecooper said in Passing list to class init, pyQt:

inaccessible

What do you mean by "inaccessible"?
Also, how do you pass the list to the constructor?
And this is wrong:

self.items(i)

must be

self.items[i]

@robbiecooper In your code there is even more wrong:

self.items.count()

does not do what you think it does and will cause you app to crash (count() counts how often an element, which is passed as parameter, occurs in the list).
It should be

len(self.items)

Thanks @jsulm!! That sorted it!
