How to save settings of a window that contains widgets with same object name?

[Ylvy]

I have a QMainWindow where I create new instances of a specific .ui created on Qt Designer, each new instance the widgets contains the same object name, example:

// test.h
#pragma once
#include "stdafx.h"

QT_BEGIN_NAMESPACE
namespace Ui { class Form; };
QT_END_NAMESPACE

class Test : public QWidget 
{
    Q_OBJECT
public:
    Ui::Form* ui;
    Test(QWidget* parent = nullptr) : QWidget(parent), ui(new Ui::Form()) {
        ui->setupUi(this);
    }
};


// mainwindow
Test test = new Test(...);   // <-
Test test_2 = new Test(...); // <- all widgets from both `Test` contains same object name

There's another way to differentiate the widgets other than using their object names when saving their values to a settings.ini file?

If no, I'm looking for suggestions in how else I could achieve this, I mean, maybe appending a special character before each widget objectName?

Exactly that, you would have to e.g. append a sequence number or a number based on which new Test() you are in to each widget's objectName() if you wish to identify it uniquely across sessions.

@JonB there's any 'easy' way to iterate every widget on a ui?

parentWidget->findChild<QWidget *>()

If you really need to "save state" it's more usual to create and save some model than expect to find widgets and know what to save from them. Up to you.
