pyqt5选中item时，如何在组合框中显示item？

Question

I need to display the element in combo box's text box only when the element is selected other wise it should be blank in Pyqt5. Say I added elements like Apple, orange, grapes and mango in the pyqt5 combo box. Usually the element apple appear in combo box's text box with out selection. But I need the element to be displayed only after i select this item or any element. Is there a way to do this?

If you just want the QComboBox to be empty until an item is selected from the drop down box, you can use .setCurrentIndex(-1) .
