what about setReadOnly(bool) in QComboBox

it would be nice for some applications to have a setReadOnly() functionality in QComboBox, as it is available in QLineEdit,

i.e. if the QComboBox is set read-only, it is no longer possible to change it's contents, but it is not drawn disabled.

I attatched a quick and dirty solution I came up with. It basically swallows all events (mouse wheel, key presses, popup) that would cause a change of the displayed value.

It would be nice to also deacivate the drawing of the drop-down indicator when in read-only mode.
