PyQt5 - How to delete all the items in ComboBox?

To delete all the items in a QComboBox in PyQt5, you can use the clear() method.

Here's a simple example to demonstrate:

import sys from PyQt5.QtWidgets import QApplication, QWidget, QComboBox, QVBoxLayout, QPushButton class App(QWidget): def __init__(self): super().__init__() self.initUI() def initUI(self): layout = QVBoxLayout() self.comboBox = QComboBox(self) self.comboBox.addItems(['Item 1', 'Item 2', 'Item 3', 'Item 4']) self.clearButton = QPushButton('Clear ComboBox', self) self.clearButton.clicked.connect(self.clearItems) layout.addWidget(self.comboBox) layout.addWidget(self.clearButton) self.setLayout(layout) self.setWindowTitle('Clear ComboBox Example') self.show() def clearItems(self): self.comboBox.clear() if __name__ == '__main__': app = QApplication(sys.argv) ex = App() sys.exit(app.exec_())

In the example above, there's a QComboBox filled with some items and a QPushButton. When you click on the button, the clearItems method gets called, which in turn calls the clear() method on the QComboBox, effectively removing all its items.
