simple problem about customizing QComboBox

Hi,

How can I reach to non-editable text field ( sorry but I don't know the name of it) part of QComboBox?

Actually I want to make the combobox like the following. The only thing I couldn't do in this picture is the thin blue line just up the bottom border of the combobox rectangle and around drop-down.

Hi,

In case of not understanding the situation, let me explain the problem again.

For instance, we can access drop-down sub control of QComboBox via "::drop-down" and down-arrow sub-control of QComboBox via "::down-arrow"...So how can I access lineedit-label part(the part the selected item is shown) of QComboBox?

Thanks in advance...
