Setting default value for QcomboBox as empty

Question

I'm on python 2.7 using pyqt 4.10, I've created a QcomboBox

for items in item_all:
    self.comboBox.addItem(items)

the item_all list is working perfectly but I need it to start with the default value as Empty (note that item_all list is being called from a DB table so I can't have an empty value to use it)

Answer 1

Another solution is self.comboBox.setCurrentIndex(-1). The QCombobox is blank when it is created without adding another item in the list.

Python 3.10 and PyQt6 6.5.1

Answer 2

Added a space to the item_all list before fetching it from the DB

item_all= ['',]
for items in c.fetchall():
    item_all.append(items)
self.comboBox_2.clear()
self.comboBox_2.addItems(item_all)
