--- Comment #3 from Thomas Fischer <fischer@unix-ag.uni-kl.de> ---
For future reference:
The problem as observed in the first KComboBox in my example is due to the fact
that lineEdit() on a KComboBox returns QLineEdit* although internally it is a
KLineEdit*. Calling setReadOnly(..) on this return value calls QLineEdit's
implementation, but not the one of KLineEdit.
The solution is to (dynamic|qobject)_cast the QLineEdit* to a KLineEdit*.
Calling setReadOnly on the cast's result uses KLineEdit's setReadOnly
implementation which performs proper layouting of the clear button.

KLineEdit *internalLineEdit = dynamic_cast<KLineEdit*>(comboBox->lineEdit());
if (internalLineEdit != NULL)
    internalLineEdit->setReadOnly(true);
