How to make a button the default?

[jdent]

I have this code:

    QPushButton* closeButton = new QPushButton(tr("&Close"));
    QPushButton* revertButton = new QPushButton(tr("&Revert"));
    QPushButton* submitButton = new QPushButton(tr("&Submit"));

    closeButton->setDefault(true);

    connect(closeButton, &QPushButton::clicked, this, &PasswordDetailsDlg::close);
    connect(revertButton, &QPushButton::clicked, this, &PasswordDetailsDlg::revert);
    connect(submitButton, &QPushButton::clicked, this, &PasswordDetailsDlg::submit);

    QDialogButtonBox* buttonBox = new QDialogButtonBox;
    buttonBox->addButton(submitButton, QDialogButtonBox::ResetRole);
    buttonBox->addButton(revertButton, QDialogButtonBox::ResetRole);
    buttonBox->addButton(closeButton, QDialogButtonBox::RejectRole);

    return buttonBox;

The close button should be the default and have the focus but it isn't!! Why??

@SGaist I finally solved the issue like this:

submitButton->setAutoDefault(false);
revertButton->setAutoDefault(false);
closeButton->setDefault(true);

Thank you all!!

Hi,

What if you set autoDefault as well ?

If you want a specific button to be default you need to call QPushButton::setDefault() on it yourself. However, if there is no default button set and to preserve which button is the default button across platforms when using the QPushButton::autoDefault property, the first push button with the accept role is made the default button when the QDialogButtonBox is shown,

As @SGaist says and the accepted solution at https://stackoverflow.com/questions/24556831/qbuttonbox-set-default-button. Perhaps especially if you are under Windows?

@SGaist I also tried it with no change!!

@jdent you don't have any button with the accept role. Why is that ?

@SGaist I finally solved the issue like this:

submitButton->setAutoDefault(false);
revertButton->setAutoDefault(false);
closeButton->setDefault(true);

Thank you all!!
