How to add items to a combobox in PyQt

Question

I need some help adding some items to a QComboBox. So I have two comboboxes, and one populates the other depending on the item selected.

My question is

Answer 1

I had to populate the comboBox using the names from a textfile

Here's the code:

    names = self.classes_names()
    self.comboBox.addItems(names)

    def classes_names(self):
        coconames = CURRENT_DIR + os.sep + 'yolo-coco' + os.sep + 'coco.names'
        with open(coconames) as reader:
            return reader.readlines()

I hope it will help someone in the future.
