Qt 4.7 : error: call of overloaded ‘QString(int)’ is ambiguous

[Astronomy]

Hello,

today i tried to port my App from Qt 4.5.3 to Qt 4.7 (under ubuntu 32bit 10.04 )
I got several: error: call of overloaded ‘QString(int)’ is ambiguous

Detailed Error Message:
Astro_Diplom/ComaGui/ui_jobs.h: In member function ‘void Ui_Jobs::setupUi(QDialog*)’:

My custom widget "Form" is inherited from QWidget...
Many Form widgets are in Jobs and..
Jobs is inherited from QDialog and the compiler stops here..

ui_jobs.h

class Ui_Jobs
{
public:
    ...
    Physical *widgetJobTemperatur;
    ...
    void setupUi(QDialog *Jobs)
    {
 
       ...
 
       widgetJobTemperatur = new Form(Jobs);    //Compiler stops here..
       widgetJobTemperatur->setObjectName(QString::fromUtf8("widgetJobTemperatur"));
       widgetJobTemperatur->setGeometry(QRect(110, 197, 217, 117));
     }
 
}

class Ui_Jobs
{
public:
    ...
    Physical *widgetJobTemperatur;
    ...
    void setupUi(QDialog *Jobs)
    {

       ...

       widgetJobTemperatur = new Form(Jobs);    //Compiler stops here..
       widgetJobTemperatur->setObjectName(QString::fromUtf8("widgetJobTemperatur"));
       widgetJobTemperatur->setGeometry(QRect(110, 197, 217, 117));
     }

}

It seems that Qt4.7 is somehow more restrictive during compilation, than 4.5.3 ?
Under 4.5.3 everything is working fine..?

thank you for any hint,

Please post the constructor of the class Form.

class Form : public QWidget {

public:
    Form(QWidget *parent = 0, QString Name=0);
    ~Form();

class Form : public QWidget {

    ~Form();

Hmm...
Maybe i'd imported some false project settings from the previous build.
Now i have undefined References.. see pic..

QListData::detach(int)
QListData::detach_grow(int*,int) ???

i'll try qmake + clean all again..

OK,
i have figured it out.

it was the red Line, which caused the error:
QString Dir = G_cWorkSpace.fiModelsDirectory.absoluteFilePath();
fiCalculatingDirectory is from Type: QFileInfo, in my class WORKSPACE...

void Tab1::on_pushButtonSelectFiles_clicked()
{   
    QString Dir = G_cWorkSpace.fiModelsDirectory.absoluteFilePath(); //caused the error
    QFileDialog dialog( this,Dir,"(*.inp)");
...
}

void Tab1::on_pushButtonSelectFiles_clicked()
{   
    QString Dir = G_cWorkSpace.fiModelsDirectory.absoluteFilePath(); //caused the error
    QFileDialog dialog( this,Dir,"(*.inp)");
...
}

changing it to:

void Tab1::on_pushButtonSelectFiles_clicked()
{   
    QString Dir;
    Dir = G_cWorkSpace.fiModelsDirectory.absoluteFilePath();  // problem solved
    QFileDialog dialog( this,Dir,"(*.inp)");
...
}

void Tab1::on_pushButtonSelectFiles_clicked()
{   
    QString Dir;
    Dir = G_cWorkSpace.fiModelsDirectory.absoluteFilePath();  // problem solved
    QFileDialog dialog( this,Dir,"(*.inp)");
...
}

solved the problem
