Problem in the QFileDialog

Hai guys,


Version : Qt 3.3.4
Problem : Problem in the MODEL property of a QFileDialog



I have the following windows or objects in screen:-

1. MyMainWindow
2. MyWizard ( textBox, BrowseButton , CancelButton.. )
3. QFileDialog

The parent-child realation is setted in the same order as above.

While Applicaitons loads the following will be the senario.....
1. MyMainWindow comes
2. while clicking one menu , MyWizad comes with a BROWSE-BUTTON
3. While clicking on BROWSE-BUTTON , the below method <code> saveInputDataToFile ( const QString& inputName, const Q_ULLONG& inputSize, QWidget* parent ) </code> will be invoked to popup a QFileDilog

Code:

---

void MyMainWindow :: saveInputDataToFile( const QString& inputName, const Q_ULLONG& inputSize , QWidget* parent )
{
-------
// parent = MyWizard object
QFileDialog * obj = new QFileDialog (  parent , "", true) ;
 
QString destFilePath = obj->getSaveFileName( QString::null, QString::Null, parent );
-------
}

---

My problem is that .....

1 .While showing the " QFileDialog ", if am clicking on the MyMainWindow ,
2. then the MyWizard's ( shows in between MyMainWindow and QFileDialog ) window highlighted , cursor will be in the wizard ( in a textBox near to BrowseButton )
3. and we can access BUTTONS using tab Key. Even we can CLOSE that Wizard using KEYBOARD, At the same time we can see the QFileDialog in the screen with out MyWizard


I want to restrict this KEYBORD access in MyWizard...please help me


Thank You.

What is "parent" in the above code?

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 );
-------
}

[HTML]
This is the parent -child flow....
+--------------------------+
| MyMainWindow |
+----------^--------------+
|
+---------------------------+
| MyWizard |
+-----------^--------------+
|
+--------------------------+
| QFileDialog |
+--------------------------+
[/HTML]

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

Code:

---

QString dest = QFileDialog::getSaveFileName(parent);

---

i have tried this also

Code:

---

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

---

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

Code:

---

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

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

Code:

---

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

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

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.

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.
