QLineEdit text() crash - Qt3

[user_mail07]

Hi,

I am getting a crash while trying to get text() from QLineEdit. I am setting a text on lineEdit in connected slot. However when I tried to get back that text I am getting crash.
I am using Qt3 setText() method of QlineEdit to set the text to the lineEdit.

Here's the code snippet:

I created two classes Class CMain1 and Class CTestApp

class CMain1 
{
 
Q_OBJECT:
----
public:
 
 
QString SaveFileName( ) { return strFileTest or m_pLineEdit->text() ;}
 
public slots:
 
void ChooseFile();
 
private:
 
QPushButton * m_pPushButton;
QLineEdit * m_pLineEdit;
QString strFileTest;
};
 
//I m connecting a push button clicked signal to ChooseFile slot :-
 
connect(m_pPushButton, SIGNAL(clicked()), SLOT(ChooseFile());
 
void CMain1::ChosseFile()
{
  strFileTest = "SomeValue";
   m_pLineEdit->setText(strFileTest);
 
//Applications behaves as expected here ..sets the desired text to the line edit.
}
 
Class CTestApp
{
	Q_OBJECT:
 
	public:
 
	void GetAppName( ) ;
}
 
void CTestApp::GetAppName()
{
     CMain1 pMain;
 
   QString str = pMain.SaveFileName();
 
  // The problem is application crashed at SaveFileName() call.
}

class CMain1 
{

Q_OBJECT:
----
public:


QString SaveFileName( ) { return strFileTest or m_pLineEdit->text() ;}

public slots:

void ChooseFile();

private:

QPushButton * m_pPushButton;
QLineEdit * m_pLineEdit;
QString strFileTest;
};

//I m connecting a push button clicked signal to ChooseFile slot :-

connect(m_pPushButton, SIGNAL(clicked()), SLOT(ChooseFile());

void CMain1::ChosseFile()
{
  strFileTest = "SomeValue";
   m_pLineEdit->setText(strFileTest);

//Applications behaves as expected here ..sets the desired text to the line edit.
}

Class CTestApp
{
	Q_OBJECT:
	
	public:
	
	void GetAppName( ) ;
}

void CTestApp::GetAppName()
{
     CMain1 pMain;

   QString str = pMain.SaveFileName();

  // The problem is application crashed at SaveFileName() call.
}
