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

Assuming list1 is a list of strings, then you can simply add them all at once using the addItems method:

self.comboBox_2.clear()
self.comboBox_2.addItems(list1)

Note that you are probably using QApplication.translate in the wrong way in your example. If you want to make it possible for the strings in list1 to be translated into a different language, you should do that when you create the the list, and use string literals.

For example:

list1 = [
    self.tr('First Item'),
    self.tr('Second Item'),
    self.tr('Third Item'),
    ]

Also note that the _fromUtf8 function is only really useful if you're using string literals containing non-ascii characters in your code - otherwise, it's basically a no-op.

EDIT

If your list contains, say, tuples of pixmaps and text, then you can use something like this:

self.comboBox_2.clear()
for pixmap, text in list1:
    self.comboBox_2.addItem(QIcon(pixmap), text)
