Let me try with simple project as you suggested.

Thanks

Hi @ambershark,
I altered device vendor's sample gui application, comment all widgets and widget-items. Added the code available in qt documentation to test QInoutDialog:getItem.
Still same error.

Thanks

Hi @Kashif,

I got the following reply from my device vendor:

I checked on our SDK and QInputDialog is disabled from the toolchain by default in the QtExtended from qtopia, you can look at
http://doc.qt.io/archives/qt-4.8 and look for an alternative. the list of disabled elements by qtopia can be found at
/opt/toolchain/arm-unknown-linux-gnueabi/sysroot/usr/QtopiaSDK/qtopiacore/qconfig-qpe.h
in your toolchain

Can you please suggest an approach to achieve my target:

0> User have Purchase Ticket / Refund Ticket options
1> User selects purchase ticket
2> Application lists types of tickets
    a> User Selects ticket or cancel (until completion/user selection step 3 should not execute)
3> Do purchase process or exit purchase process

Thanks

Hi,

You can build your own QDialog for that purpose or depending on your application a QWizard might also be an option.

@Kashif said in 'QInputDialog' has not been declared - embadded development:

Well that makes a lot more sense. :)

Like @SGaist said, just write your own QDialog. Make it modal by calling it with myDialog->exec() and test that return code for a QDialog::Accepted in order to proceed or QDialog::Rejected in order to exit the process.

Kashif

Hi @SGaist and @ambershark,

I am planned to create custom dialog using QDialog class, in parallel I have placed a question to device vendor if I can use QDialog? or if I can use QTCore application. I hope I'll get positive reply for at least one of them.

Thanks for your time and response.

ambershark

@Kashif If you can't use QDialog, there are other ways to simulate it, getting user input from a qwidget and not allowed it to proceed until your widget is closed.

And if you can't use qwidgets, well then you don't really have a gui and none of this matters. :)

Hi @ambershark,

PreviouslyI have created secondary widget and called it but my parent widget code was also running this was the reason I moved towards QDialog.
The good new is I have created a custom sample dialog class and it is working as required. Now I have to make it similar to QInputDialog. Following is the code from my custom dialog class:

#ifndef APPSELECTIONDIALOG_H
#define APPSELECTIONDIALOG_H


#include <QtGui/QDialog>
#include <QtGui/QVBoxLayout>
#include <QtGui/QLineEdit>
#include <QtGui/QPushButton>
//#include <QtGui/QLabel>

class appSelectionDialog: public QDialog
{
    Q_OBJECT
public:
    explicit appSelectionDialog(QWidget *p = 0): QDialog(p) {
        QVBoxLayout *layout = new QVBoxLayout(this);
        lineEdit = new QLineEdit(this);
        QPushButton *button = new QPushButton("Ok", this);
        layout->addWidget(lineEdit);
        layout->addWidget(button);
        setLayout(layout);

        connect(button, SIGNAL(clicked()), SLOT(accept()));
    }

    QString getText() const {
        return lineEdit->text();
    }
private:
    QLineEdit *lineEdit;
};

#endif // APPSELECTIONDIALOG_H

Calling function:

    appSelectionDialog dialog; // dialog object exists
    (void) dialog.exec();    // dialog is visible
    DBGPRINTF(LOG_INFO, CLASS_EMV,"Text [%s]", dialog.getText().toLocal8Bit().constData() );  //This method prints the text on console in c format

If you have reference to make it similar to QInputDialog please share it :)

Thanks

Hi @ambershark,

Can you please help me how do I modify the constructor to get the parameters similar to QInputDialog::getItem

Thanks

Kashif

Hi @ambershark,

I have created the constructor successfully and it display the item in comboBox.

Thanks for your help.

ambershark

@Kashif Nice! Glad you got everything working.

Don't forget to mark the topic as solved. :)
