QDialog problem

[Fillinger]

Hi all,

I have a QMainWindow and I need to use a QDialog (modal) but no problem for that.

I run my app on the simulator, everything works fine but when I want to build and deploy on device,
I have this error : "undefined reference to `FormZone::FormZone(QWidget*)"

I don't really understand where come from the problem because all works on simulator
Maybe I miss something so here is the code :

if(!fZone);
{
fZone = new FormZone(this); // Error for this line
connect(fZone,SIGNAL(accepted()),this,SLOT(ZoneAccepted()));
}

fZone->exec();

Thank you for help.

Hi, Fillinger

Running the application in the simulator and in the device both are different thing.
Every time it is not necessary that the application can run successfully.

Does Qt library is correctly installed in your mobile. ?
Which phone you are using ?
And what version of Qt You have ?

Best regards,
RaHuL

Hi RaHuL,

first thanks for answer.

I use a nokia 5800 and I have install Qt_installer.sis that comes with the SDK. TRK is also install. And I use Qt 4.7.0.

Before the creation of the QDialog, my app deploy and run correctly on the device.
if you need other information, tel me.

Thanks for help.

Hi,

If it works in the emulator then it should work in the device also.

Have you gone through this article : http://wiki.forum.nokia.com/index.ph...ng_with_AppTRK
Do according to this article.

Cheers,
RaHuL

Where is FormZone defined? If its in a separate library then you may need to recompile that for the phone.

Hi danhicksbyron,

formzone is defined in my QMainWindow. I check my TRK version too and it is up to date. I don't find solution until now.

I hope someone had the same problem and resolve it.

Thanks for you reply.

[divanov]

formzone is defined in my QMainWindow.

This makes no sense, however, could you please provide full log of build process. In this document page 11
http://www.forum.nokia.com/info/sw.n...ia_Qt_SDK.html

hi divanov,

here is the log of compiler :

I can send you all the build log because there is too much line (a lot of warning)

Hope you will find something.

Thank you.

I would try to clear project and rebuild it again. qmake is not perfect in identifying re-build need. Also, please, show your project file.

[Fillinger]

I try to clean and rebuilt but nothing change, always say
"undefined reference to 'FormZone::FormZone(QWidget*)'.

And I supose that is not because I try to pass a QMainwindow to my FormZone, QMainWindow inherit from QWidget isn't it ?

here the .pro file

thanks you for your time pass to help me.

[divanov]

Do you have

#include "formzone.h"

in formmain.cpp?

[Fillinger]

I have the

#include<formzone.h>

in the .h file, not in the .cpp file.

I try to put it now in cpp but no change.

[divanov]

Well, probably you should share the whole source code.
