Thank you for your advice.

I'll give it a try.

There you could override the data() method and "translate" strings retrieved from the database into strings you want shown in the combo box. It's one way, without too much disruption. You might write your own QAbstractProxyModel, or you might derive from QIdentityProxyModel as the starting point:

Because it does no sorting or filtering, this class is most suitable to proxy models which transform the data() of the source model

QAbstractProxyModel

Are you saying that it is possible to use the QAbstract proxy model?

@JonB said in It's a combo box question linked to the database:

and you want to change their text, one way would be to interpose a QAbstractProxyModel-derived class with your "translations".

There is no separate translation.

You have information about the row.

ex)

JJ0101= 중앙101블록

There's a list in this format.

I want to print it out in Korean.

Do you already have the translations somewhere?

I'm sorry for my poor translation.

To give you more explanation,

In the DB column,

If there are 1, 2, and 3 lines,

I'm going to put the row in QCombox.

But the language in line 1, line 2, line 3 is English

I want to print it out in Korean.

But you may mean something quite different! No idea what your "change it using the ini file" might mean.
