QDialogButtonBox ResetRole

[mero]

I have QDialogButtonBox with "Reset" "OK" and "Close"
To OK and Close I use:

QObject::connect(ui.buttonBox, SIGNAL(accepted()), this, SLOT(button_ok()));
QObject::connect(ui.buttonBox, SIGNAL(rejected()), this, SLOT(button_close()));

QObject::connect(ui.buttonBox, SIGNAL(accepted()), this, SLOT(button_ok()));
QObject::connect(ui.buttonBox, SIGNAL(rejected()), this, SLOT(button_close()));

To copy to clipboard, switch view to plain text mode 

How write code to Reset button ? I don't find any examples for ResetRole ...

See the QDialogButtonBox::clicked() signal.

something like this ?

...
QObject::connect(ui.buttonBox, SIGNAL(clicked(QAbstractButton*)), this, SLOT(buttons(QAbstractButton*)));
}
 
void class::buttons(QAbstractButton *button)
{
    if (button->text() == tr("Reset"))
        button_reset();
    else if (button->text() == tr("OK"))
        button_ok();
    else if (button->text() == tr("Close"))
        button_close();
}

...
QObject::connect(ui.buttonBox, SIGNAL(clicked(QAbstractButton*)), this, SLOT(buttons(QAbstractButton*)));
}

void class::buttons(QAbstractButton *button)
{
    if (button->text() == tr("Reset"))
        button_reset();
    else if (button->text() == tr("OK"))
        button_ok();
    else if (button->text() == tr("Close"))
        button_close();
}

Yes, but better:

if (ui.buttonBox->button(QDialogButtonBox::Help) == button)
  // Help was clicked

if (ui.buttonBox->button(QDialogButtonBox::Help) == button)
  // Help was clicked

In qt 4.7 I found that a beter solution is

if(ui->buttonBox->standardButton(button) == QDialogButtonBox::Reset)
{
   //Do Something
}

if(ui->buttonBox->standardButton(button) == QDialogButtonBox::Reset)
{
   //Do Something
}

And would you kindly elaborate, why your solution is better? It seems to me you are saying that

int i = 1 + 2;

int i = 1 + 2;

To copy to clipboard, switch view to plain text mode 

is better than

int i = 2 + 1;

int i = 2 + 1;
