Name an unknown number of widgets with a name followed by an integer

[N1coc4colA]

Hello,
I search on the web since 3 days, and I can't find the answer...
I have an unknown number, with this integer, I create the right number of widgets using a loop and the integer. But I send data to the widget, the last widget send data and it create a bug: the first element created store the last element's data. I want to solve it by using something like an array (std::vector / std::array) or x = setObjectName("y" + QString::number(i); but after, I have some problems: I don't know how to use or it give some access problems. Have someone a simple solution or a template to help me?
Thank you for every reading or answer, my code is available at: https://github.com/N1coc4colA/Mails , the problem is in the mainwindow.cpp. Please note the fact that MailButton don't works as it should.

sorry for my ignorance but after I had a look into your git I couldn't find the code that you speaking about... can you post it here, please. and let us know when you get the error on the creation or when you use it??

Look at the file "mainwindow.cpp", "mainwindow.h" and "mailbutton.*" At the root of the git. I can't past the code now, I havent my pc.
https://github.com/N1coc4colA/Mails/blob/master/mainwindow.cpp
Look at the end of the file, in the function "ChilkatSample()"

Hi
Do you mean the

 int numEmails = bundle->get_MessageCount();
while (i < numEmails) {

loop `?

[arsinte_andrei]

qDebug() << "Opening Mailbox (inbox) was successfull";

is not doing anything - is after return

mail->setObjectName(magik);

1. this has to be exactly after the creation of the object - is the NAME of the object you created -
2. you create to many objects with the very same name - names have to be unique
3. use something like

mail->setObjectName(magik.append(QString::number(i)));

hope that helped

[N1coc4colA]

Yes, but after, to access it with a pointer, I have to use what? magik.append(QString::number(i)))->.... ?

Hi
That only sets the object name.
If you need pointers to the widgets, you should keep a list around
or build one on demand with
FindChildren.

[N1coc4colA]

OK, thank you. I think I'll use the second one, Do a list is hard, prefer the second, due to the unknown number of widgets and the fact that I need to use connect(), it'll be better for me.Thanks for your help, Master of Qt, who's on every chats, I'll maybe ask you for help in the future. ;)

It's not that hard... but you have to ensure, that everything is cleaned up correctly.
Maybe a vector / list of QSharedPointers.

connect(this->findChildren<MailButton *>("mail" + QString::number(i)), SIGNAL(Processed(QString)), this, SLOT(MessageFallBack(QString)));
I can use it, so?

No, this can't work.
You have to call connect for every button. You can do this in a loop.

[N1coc4colA]

@jsulm, I have my loop, all the code is already in a loop. I have a loop of the number of mails, it create the MailButton I talked about. I had to change the name in depending of the no. and to use some pointers and some connect(), now it's fix. You said that I have to put it the loop, so it's right. But, as I said it should work, right?

@N1coc4colA

You can not loop over this. You have to use an object with an index.

For example:

QVector <MyButtons*> m_buttons;

for (int i = 0; i < 10; i++)
{
    m_buttons.pushback(new MyButton ());
    connect (m_buttons.at(i), &MyButton::clicked, dest, &MyDestination::DoSomething);
}

OK, thank you for the answer
