How to add two label-field pair as one row to QFormLayout?

So I have QFormLayout that manages my QLabel-QLineEdit pairs just fine.
Problem is, that I need to achive something like this: enter image description here

Horizontal border/tittle isn't a problem, but "Street"-"Apartment"/"Post code"-"City" pairs are.

So my question is: how to add two pairs of QLabel-QLineEdit as one row to QFromLayout?

If it's not possible with QFormLayout, do you have any suggestion about achivining the same with other layout (QGridLayout, I guess)?

Keep in mind, that labels can have different size proportions after translated to other languages.

Thanks in advance!

Solution

Thanks for all the response!

I've ended up adding QLabel as label and QHBoxLayout with QLineEdit, QLabel and QLineEdit as field to QFormLayout. Something like:

QLabel firstLabel, secondLabel;
QLineEdit fisrtEdit, secondEdit;

QHBoxLayout hBoxLayout;
hBoxLayout.addWidget(firstEdit);
hBoxLayout.addWidget(secondLabel);
hBoxLayout.addWidget(secondEdit);

QWidget container;
container.setLayout(hBoxLayout);

myFormLayout.addRow(firstLabel, container);

do the trick!

Also, if you're planing to add more than one row like this, I'll need to set all secondLabels to one fixed width. I did this by iterating over all secondLabels twice: first time for finding maximux width and second for setting this width to all of them.

A bit hacky, but I couldn't find a better way so far. Solution with QGridLayout would be even more complicated, on my opinion.
