QPushButton, QTabOrder and return key

Hello,
I have created two buttons:

Code:

---

cancelButton = new QPushButton("Cancel");
  layout->addWidget(cancelButton, 2, 0);
  submitButton = new QPushButton("Submit");
  layout->addWidget(submitButton, 2, 1);

---

and connected them like this

Code:

---

connect(cancelButton, SIGNAL(clicked()), this, SLOT(cancel()));
  connect(submitButton, SIGNAL(clicked()), this, SLOT(checkLogin()));

---

then, I specified some tabordering

Code:

---

setTabOrder(usernameLine, passwordLine);
  setTabOrder(passwordLine, submitButton);
  setTabOrder(submitButton, cancelButton);

---

once the password is entered and I press tab, the submitButton is highlighted but pressing the return key on my mac does not trigger anything. If I click the button with the mouse, it works fine. I am using Qt 4.2.0-rc1.
Thanks for any help

AFAIR return key activates the default button, while space activates the button with focus.

I think you should specify the submit button as "autodefault" or "default".
