How to remove Scroll bar of QCombo Box

[Lykurg]

Hm, is this task homework you have to do?

And you won't find an easy solution, because removing the "drop down" from a combobox is nonsense (like having a button without a click-able area). So no build in solution for that, but you can subclass the style and change the drawing there. Or use a proxy style.

Perhaps you really want a QLineEdit, QCompleter and QValidator.
