How to disable NextButton in QWizard ?

Hi!

I am working in Qt 4.3 and have created four pages. In the second page, it has a start pushbutton which is used to calibrate cards. I want to make the start pushbutton enabled and the Qwizard NextButton disabled when initialized. To do this I tried to disable the button in the initializePage() or QWizard’s nextId() funtion, but both do not work.

In Qwizard::nextId():

Code:

---

button(Qwizard::NextButton)->setEnabled(false);

---

In QwizardPage::initializePage():

Code:

---

QabstractButton *btn = parentHandle->button(Qwizard::NextButton);
Btn->setEnabled(false);

---

After I called wizard->show(), I do the following:

Code:

---

wizard->button(Qwizard::NextButton)->setEnabled(false);

---

This can disable the QWizard’s NextButton, but if I call it before wizard->show(), it does not work.
If I connect the start pushbutton click signal to a slot, which is to disable the Qwizard’s NextButton, when I click the button it can disable the QWizard’s NextButton. However, I don’t want it to be disabled when I click the button, only when it is initialized.

Any suggestion will be greatly appreciate!

Take a look at the docs of QWizardPage::isComplete().

Thanks a million, It solved my problem, i did the following:

Code:

---

bool QWizardPage::isComplete()const
{
    if (startPushButton->isEnabled()) {
    return false;
    } else {
    return true;
    }
}

I am puzzled why I can't disable the QWizard's NextButton in QWizardPage::initializePage(). I did the following:

Code:

---

QAbstractButton *button = wizard()->button(QWizard::NextButton);
button->setEnabled(false);

---

If you have any suggestions why this is the case, I'd be interested to hear the reason!
Any help would be appreciated!

Maybe the button gets enabled right after you disable it?
