QWizard : clear focus Next Button

[fgdevel]

@mrjj

Yes, it's just the focus I want to remove.
Because I use i QWizard page, it's not simple

[mrjj]

@fgdevel
By remove focus you mean so that if user hit say enter, then nothing happens?
Or what is thee goal of what you want?

[fgdevel]

@mrjj

yes it's the goal. When the user press Enter key, nothing happens

[mrjj]

@fgdevel
but that is 100% what validatePage does.
If you return false, the Next dont work/nothing happens.
Dont matter if you hit enter or click on it.

So that is why im confused of what you really mean.

@mrjj

I want Next button works. But just focus not

[mrjj]

@fgdevel
ok so you want user to click on it.

Have a look at setFocusProxy();

http://ldc.usb.ve/docs/qt/dialogs-complexwizard.html

It seems that you can call that in a Pages constructor and then it will give focus to that widget when page is
shown.

I have used diffrent setFocus functions but none of them seems to work...

Hi
You are right. by magic it can still hit enter on Next...

I changed sample "trivialwizard" to use eventfilter.
That can eat the enter key. :)
so key changes are
class myEventFilter: public QObject // the event filer
app.installEventFilter(new myEventFilter()); // using the filter

#include <QtWidgets>
#include <QTranslator>
#include <QLocale>
#include <QLibraryInfo>
QWizard* wizardp;
QWizardPage* createIntroPage() {
  QWizardPage* page = new QWizardPage;
  page->setTitle("Introduction");

  QLabel* label = new QLabel("This wizard will help you register your copy "
                             "of Super Product Two.");
  label->setWordWrap(true);
  QLineEdit* nameLineEdit = new QLineEdit;

  QVBoxLayout* layout = new QVBoxLayout;
  layout->addWidget(label);
  layout->addWidget(nameLineEdit);
  page->setLayout(layout);


  wizardp->button(QWizard::CancelButton)-> setFocus();
  return page;
}

QWizardPage* createRegistrationPage()
{
  //! [3]
  QWizardPage* page = new QWizardPage;
  page->setTitle("Registration");
  page->setSubTitle("Please fill both fields.");

  QLabel* nameLabel = new QLabel("Name:");
  QLineEdit* nameLineEdit = new QLineEdit;

  QLabel* emailLabel = new QLabel("Email address:");
  QLineEdit* emailLineEdit = new QLineEdit;

  QGridLayout* layout = new QGridLayout;
  layout->addWidget(nameLabel, 0, 0);
  layout->addWidget(nameLineEdit, 0, 1);
  layout->addWidget(emailLabel, 1, 0);
  layout->addWidget(emailLineEdit, 1, 1);
  page->setLayout(layout);

  return page;
  //! [4]
}
//! [2] //! [4]

//! [5] //! [6]
QWizardPage* createConclusionPage()
//! [5] //! [7]
{
  //! [7]
  QWizardPage* page = new QWizardPage;
  page->setTitle("Conclusion");

  QLabel* label = new QLabel("You are now successfully registered. Have a "
                             "nice day!");
  label->setWordWrap(true);

  QVBoxLayout* layout = new QVBoxLayout;
  layout->addWidget(label);
  page->setLayout(layout);

  return page;
  //! [8]
}
//! [6] //! [8]
// this you need
class myEventFilter: public QObject {
 public:
  myEventFilter(): QObject() {}
  ~myEventFilter() {}
  bool eventFilter(QObject* object, QEvent* event) {
    if (event->type() == QEvent::KeyPress) {
      QKeyEvent* key = static_cast<QKeyEvent*>(event);
      if ( (key->key() == Qt::Key_Enter) || (key->key() == Qt::Key_Return) ) {
        event->ignore();
      } else {
        return QObject::eventFilter(object, event);
      }
    }
  }
};

//! [9] //! [10]
int main(int argc, char* argv[])
//! [9] //! [11]
{
  QApplication app(argc, argv);

#ifndef QT_NO_TRANSLATION
  QString translatorFileName = QLatin1String("qt_");
  translatorFileName += QLocale::system().name();
  QTranslator* translator = new QTranslator(&app);
  if (translator->load(translatorFileName, QLibraryInfo::location(QLibraryInfo::TranslationsPath)))
    app.installTranslator(translator);
#endif

  QWizard wizard;
  wizardp = &wizard;
  wizard.addPage(createIntroPage());
  wizard.addPage(createRegistrationPage());
  wizard.addPage(createConclusionPage());

  wizard.setWindowTitle("Trivial Wizard");
  wizard.show();
  app.installEventFilter(new myEventFilter()); // install filter
  return app.exec();
}

I've found a solution with :

this->setOptions(QWizard::NoDefaultButton);
this->setOption(QWizard::NoDefaultButton, true);

@fgdevel
