How to transfer data entered in a QWizard to other classes?

[wysota]

Thanks so much for the code snippet, I didnt find this anywhere, in no example! Perhaps they considered normal people would know this..(qobject_cast). I had no clue that that must be done :< Thank you

It's there in many places, I assure you.

About ::next(), I understand you are saying to Not reimplement ::next, but reimplement ::nextId() instead. I want to do some stuff when the user clicks "next" so ::next() seems more intuitive..

No, in that case you need to reimplement QWizardPage::initializePage() on the next page you want to show.

PS: apparently if I do in myWizard constructor :
setButton(QWizard::NextButton, mybuton);
connect ( mybuton, SIGNAL(clicked()), this, SLOT(my_slot()));

my_slot() is executed AFTER the next Page's initializePage() ?!?! (is this logical?)

Yes, it's logical.


Read this article, it might help you understand how wizards work:

ok, i dont know if this is normal or not.... but apparently after casting i cannot access data members of wiz-> or even methods of wiz that themselves access members of the wizard object. I get a SIGSEGV upon running the program... (tried with static_cast too, although i have the q_object macro)

Check if wizard() doesn't return 0 or that qobject_cast doesn't return 0.

in myPage1 constructor:
 
  qDebug()<< this->wizard()    ;  // outputs  QObject(0x0)
 
  myWizard *wiz = qobject_cast<myWizard*>(     wizard()  );  //also tried  myWizard *wiz = qobject_cast<myWizard*>((myWizard*)     wizard()  ); 
 
  if(wiz) {  wiz->my_slot("testing") ;  //does not get executed  }

in myPage1 constructor:

  qDebug()<< this->wizard()    ;  // outputs  QObject(0x0)

  myWizard *wiz = qobject_cast<myWizard*>(     wizard()  );  //also tried  myWizard *wiz = qobject_cast<myWizard*>((myWizard*)     wizard()  ); 

  if(wiz) {  wiz->my_slot("testing") ;  //does not get executed  }

To copy to clipboard, switch view to plain text mode 

i set the Page in the myWizard constructor using : addPage( new myPage1( ) );

What am i screwing up?

[wysota]

Before you add the page to the wizard (which happens after the page constructor is executed) the page doesn't belong to the wizard so wizard() returns 0.

I am so ashamed of myself. I am a complete idiot. I will give up programming and go be a janitor... Qt is great though....
