Problem in the QFileDialog

[wysota]

What is "parent" in the above code?

[joseph]

void MyMainWindow :: saveInputDataToFile( const QString& inputName, const Q_ULLONG& inputSize , QWidget* parent )
{
-------
// Parent = MyWizard ;

QFileDialog * obj = new QFileDialog ( parent , "", true ) ;

QString destFilePath = obj->getSaveFileName( QString::null, QString::Null, parent );
-------
}

This is the parent -child flow....
+--------------------------+
| MyMainWindow |
+----------^--------------+
|
+---------------------------+
| MyWizard |
+-----------^--------------+
|
+--------------------------+
| QFileDialog |
+--------------------------+

getSaveFileName is a static method, please use it as one.

QString dest = QFileDialog::getSaveFileName(parent);

QString dest = QFileDialog::getSaveFileName(parent);

i have tried this also

void MyMainWindow :: saveInputDataToFile( const QString& inputName, const Q_ULLONG& inputSize , QWidget* parent )
{
-------
 QString destFilePath =  QFileDialog::getSaveFileName(  ..., .., ..., ..., parent );
 
-------
}

void MyMainWindow :: saveInputDataToFile( const QString& inputName, const Q_ULLONG& inputSize , QWidget* parent )
{
-------
 QString destFilePath =  QFileDialog::getSaveFileName(  ..., .., ..., ..., parent );

-------
}

To copy to clipboard, switch view to plain text mode 

But at this time also the keyboard is working in MyWizard ...and i can even close it by using TAB-KEY , without closing the FileDialog


please help me...

Are you sure "parent" is set to the wizard? Can you confirm that? (for example by using

parent->metaObject()->className()

parent->metaObject()->className()

Edit: The attached code works correctly for me (compile using qmake -project && qmake && make)

You once again missed that it is related to Qt3

So? Does it matter? The code is practically the same and works the same, here - try it.

It does not matter to you or to me. But the question is does it matter to him ?

The question was asked in "Qt programming" section, not in the "Newbie" section so I can assume that the person asking the question has some skills to modify the code so that it fits Qt3. The only changes required were modifying the includes and the file dialog line. Anyway, just to make things clear, I didn't use Qt4 code on purpose, I just didn't notice one was using Qt3.

I confirmed that , " QFileDialog's " parent is " QMyWizard " in run time.
I have debugged the code it shows ....

void MyMainWindow :: saveInputDataToFile( const QString& inputName, 
                                                                  const Q_ULLONG& inputSize , 
                                                                  QWidget* parent )
 
    {
 
      -------
      const char * Name = parent->className();
      // in run time the Name is  MyWizard.
 
     QString destFilePath =  QFileDialog::getSaveFileName(  ..., .., ..., ..., parent );
 
 
 
      -------
 
     }

void MyMainWindow :: saveInputDataToFile( const QString& inputName, 
                                                                  const Q_ULLONG& inputSize , 
                                                                  QWidget* parent )
   
    {

      -------
      const char * Name = parent->className();
      // in run time the Name is  MyWizard.
    
     QString destFilePath =  QFileDialog::getSaveFileName(  ..., .., ..., ..., parent );

       

      -------

     }

I think i have to do some thing else ...


Thank you so much for sparing your time for me

Is the wizard a QDialog subclass (note that QWizard is QDialog subclass as well)?

Try the code I attached in the previous post, it should work for you. If it doesn't you'll know you have a buggy Qt installation. If it does, maybe it'll help you correct your code.
