Pyqt5 combobox allow search but prevent add

Question

how can i make QComboBox allow search but preventing user from adding new item my code :

self.products = QtWidgets.QComboBox(self.conts[self.ind])
self.products.setEditable(True)
self.products.resize(190, 30)
self.products.move(400, 20)
self.products.setStyleSheet('background:#2c3e50')
self.products.show()

self.products.setEditable(True) is not what i need because user can type any thing

How to prevent user from adding new item , just search for currently setted items

Answer 1

As you point out you have to enable the editable property and set the insertPolicy property to QComboBox::NoInsert :

import sys

from PyQt5 import QtWidgets


if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    w = QtWidgets.QComboBox()
    
    w.addItems(["One", "Two", "Three", "Four", "Five"])
    w.show()
    sys.exit(app.exec_())
