<![CDATA['QInputDialog' has not been declared - embadded development]]>Hi All,

Details/Scenario:
I am developing qtopia widget application that required user selection at a point. The main target is during the user selection I want my application code afterwards should be paused until user selects or cancels the provided option.

Testing:
I tried to create widget2 and set is using setCentralWidget() resulting ui is changed but the next remaining code also executed.
Issue:
I searched and found that I should use QInputDialogue class to achieve my target. I create the code and include the header file but I am getting error : 'QInputDialog' has not been declared

If anybody can help me to solve this issue or any alternative to achieve my target scenario.

Thanks
Kashif

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

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

Thanks for your help.

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

Thanks

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

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

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.

is disabled from the toolchain by default in the QtExtended from qtopia

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.

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

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

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

Can you check permissions on the QInputDialog files in /opt/ .. those are the ones it should be using to cross compile. Make sure you have read permissions to them.

Next, let's see if maybe the qmake you are using is finding the wrong qmake or something, run qmake -query and paste results here.

I'm kind of reaching at this point though. Everything looks good so far like it should work.

Another idea is create a simple project that just has a main and a QInputDialog::getText or something and see if you can get that to build with your cross compiler toolchain. Take all the complexity from your actual project out of it.

Also you can check on your embedded device if you actually have the QInputDialog file. Most embedded devices are linux, so you should be able to use the command find /path/to/your/qt -iname "qinputdialog" and see if it actually exists in the Qt installed on your target system.

The actual build output and possibly the code file where you try to create the object would be helpful.

Also, if you could answer @SGaist 's questions from above that would help too.

Oh and sharing the build Makefile may help too, and your qbuild.pro file.

I have included using both ways:

#include <QInputDialog>
#include <QtGui/QInputDialog>

I am not using qmake but using make file to use cross compiler provided by the device vendor and it does not contains any configurations, whereas my configurations are placed inside project file (qbuild.pro).

QT += widgets

This configuration is not defined in ".pro" file but all widgets (gui) including text label, input line, command buttons are working fine in my application.

Thanks

The device builtin version is QT4.6/QT Extended 4.4 and I can not update QT version. Device platform is Linux Kernel 2.6.32 and development environment is Debian Linux 7.8.

Thanks

#include <QInputDialog>

Also, this is something you would need for any GUI, but make sure you have QT += widgets in your qmake.

What version of Qt are you using ?
On what platform ?
