Populate QComboBox with a list

0 votes

I'm developing a GUI dialog using PyQT4 which imports some data into a Pandas DataFrame and then plots the data to an embedded Matplotlib canvas.

I'd like to pass a list of variable from the DataFrame to the combo box. My first attempt was:

list = list(df.parameter,unique())
self.FirstComboBox = QtGui.QComboBox()
self.FirstComboBox.addItems(list)

But on running this I get

TypeError: QComboBox.addItems(QStringList): argument 1 has unexpected type 'list'

I've seen examples where a sorted list of dict keys is passed to a combo box, so I'm confused that I can't pass a list.

It looks like you're using the old v1 api. You can use the newer api, which removes the need for casting strings to QStrings (or QStringLists in this case).

import sip
# Do this before you import PyQt
sip.setapi('QString', 2)
