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

Question

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!

How about simply clicking this together in QtDesigner? Should be rather straightforward. And yes, you could use a QGridLayout in code and simply put Appartment and City into column 1 while the single lines have columnSpan set to -1. — Robert, Jul 03 '15 at 22:26

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.

I think you should create a QWidget with get a Vertical layout with the QLabel and the QLineEdit then add the label in the QFormLayout. I don't get the time to show you an example but think about to create an ui with a QLabel-QLineEdit in a QVBoxLayout. By creating an ui you can add any widget in with the same form easily.

So you mainWindow. you main layout -> create your widget -> add vertical layout -> add your QLabel and QLineEdit to yout widget layout -> add your widget to your main layout.

I think you should show a QtCreator-QtDesigner tutorial. It will take you some time but you will get really faster after.

Thanks for reply! Unfortunately, I really can't understand what do you mean. Could you describe your solution in greater details, please? – rsht Jul 03 '15 at 19:49
It's better to use nested layout management (native Qt solution). It means that you create a separate `QFormLayout` for you right column and add it using `addRow(QLayout * layout)` to your parent layout. – dazewell Jul 04 '15 at 08:45
dazewell it's way faster to use QDesigner to do the ui and it's what you do with my solution. @Roman use QtCreator. Create a new class -> Qt -> Qt form -> Widget -> in you widget.ui create a QLabel and QLineEdit, right click -> vertical layout. return in your main class where you want to add you QLabel-QLineEdit create an objet of you custom widget class then make an layout->addWidget(yourWidget); – Gabrielle de Grimouard Jul 04 '15 at 15:47

If you want to add a label without the QLineEdit to appear, you can define a QlineEdit and hide it: (the code is in python, just to show the principle)

self._dummy = QLineEdit(self)
self._dummy.hide()
layout = QFormLayout(self)
layout.addRow("text without an edit field", self._dummy)

Here is a method I just created for my solution, this is a pseudo code version that might help someone.

    def create_gb_f(self):
        gb = QGroupBox("F") 

        ly_horiz = QHBoxLayout()

        layout = QFormLayout()
        layout.addRow( label, edit)
        ly_horiz.addLayout(layout)

        layout = QFormLayout()
        layout.addRow( label, edit)
        ly_horiz.addLayout(layout)

        ly_horiz.addWidget( button)
        gb.setLayout(ly_horiz)
        return gb
