QWizard - value from previous page into next page?

[Anagha_T]

Hello Team,

I am developing a Wizard using QWizard. I have a QListWidget areaList on first page of the wizard. Per QWizardPage documentation, I have registered the widget:

registerField("areaIndex", areaList);

However, when I try to get the field "areaIndex" in the subsequent page, it gives me the row number in the QListWidget. I am interested in getting the QListWidgetItem->text() on the next page.

How do I get this text value from previous page into next page?

Please let me know.

Thank you!
Anagha

areaList->currentItem()->text();

Thank you for your reply Daniil.

However, the areaList is not visible in the next page.
Besides, I am wondering if the mehtods register() field() can be enhanced for transmitting the "areaList->currentItem()->text()" to the subsequent Wizard Pages.

However, the areaList is not visible in the next page.

Are you sure?

As seen below, the "QListWidget *areaList" is in IntroPage & hence not seen in the Survey page:



class MyWizard : public QWizard
{
Q_OBJECT

public:
enum { Page_Intro, Page_Survey, Page_Conclusion };
MyWizard(QWidget *parent = 0);

private slots:
void showHelp();
};

class IntroPage : public QWizardPage
{
Q_OBJECT

public:
IntroPage(QWidget *parent = 0);
QListWidget *areaList;
:
:
};

class SurveyPage : public QWizardPage
{
Q_OBJECT

public:
SurveyPage(QWidget *parent = 0);

:
:
};

You can move areaList to QWizard class making it accessible for all pages.

When I move the areaList to QWizard:

----------------------------------------------------------------------------------
class MyWizard : public QWizard
{
Q_OBJECT

public:
enum { Page_Intro, Page_Survey, Page_Conclusion };
MyWizard(QWidget *parent = 0);
QListWidget *areaList;
private slots:
void showHelp();
};

----------------------------------------------------------------------------------
And try to access it in other pages like:


IntroPage::IntroPage(QWidget *parent)
: QWizardPage(parent)
{
setTitle(tr("Step 1: Select an Area"));
setSubTitle(tr("..."));

MyWizard::areaList = new QListWidget;
:
:
}



I get the following compilation error:

MyWizard.h: In constructor ‘IntroPage::IntroPage(QWidget*)’:
MyWizard.h:30: error: object missing in reference to ‘MyWizard::areaList’
MyWizard.cpp:127: error: from this location

----------------------------------------------------------------------------------

Am I missing something?
How can I declare the areaList so that it's accessible to all the pages of MyWizard?

Thank you!

IntroPage::IntroPage(QWidget *parent)
     : QWizardPage(parent)
{
     setTitle(tr("Step 1: Select an Area"));
     setSubTitle(tr("..."));

     MyWizard *wizard = qobject_cast<MyWizard *>(wizard());
     wizard->areaList = new QListWidget;
}

And note you store pointer to list in MyWizard, while it's created, belongs and destroyed by IntroPage. This is design flaw and potential source of bugs.
