Problem with QLineEdit and setText

[Elmo23x]

I have a pice of code that looks like this...

...
QLineEdit *t1;
QString str;
 
t1 = new QLineEdit();
str = "hi to everybody";
 
t1->setText(str);
...

...
QLineEdit *t1;
QString str;

t1 = new QLineEdit();
str = "hi to everybody";

t1->setText(str);
...

To copy to clipboard, switch view to plain text mode 

After the execution of "t1->setText(str);" the program breaks with a segmentation fault error.

Probably I am doing something very badly.

Thank you for your help

BTW: the code compiles without any error

The code you posted should work ok.
Are you sure it crashes on t1->setText(str) and not later?
Could you show a bit more of the code before and after the lines you posted?

The exact code is this (sorry, names are in spanish):

void WInfo::cargar_info_personal()
{
  int sexo, pais;
  int dia, mes, ano;
  QString nick;
  QString nombre;
  QString apellido;
  QString ciudad;
 
  //Get the information
  datos_leer_info_personal(estDatos, &nick, &nombre, &apellido, &ciudad,
			   &sexo, &pais, &dia, &mes, &ano);
 
  QDate fecha(ano, mes, dia);
 
  t1->setText(nick);
  t2->setText(nombre);
  t3->setText(apellido);
  c4->setCurrentIndex(sexo);
  c5->setCurrentIndex(0);
  t6->setText(ciudad);
  f7->setDate(fecha);
}

void WInfo::cargar_info_personal()
{
  int sexo, pais;
  int dia, mes, ano;
  QString nick;
  QString nombre;
  QString apellido;
  QString ciudad;

  //Get the information
  datos_leer_info_personal(estDatos, &nick, &nombre, &apellido, &ciudad,
			   &sexo, &pais, &dia, &mes, &ano);

  QDate fecha(ano, mes, dia);

  t1->setText(nick);
  t2->setText(nombre);
  t3->setText(apellido);
  c4->setCurrentIndex(sexo);
  c5->setCurrentIndex(0);
  t6->setText(ciudad);
  f7->setDate(fecha);
}

To copy to clipboard, switch view to plain text mode 

I have been debugging it with gdb, and it breaks in "t1->setText(nick);" if I comment it it breaks in "t2->setText(nombre);", byt if I write "t1->setText("string");" it works without problems.

t* are declared in the header of the class and initilialized when the class is created.

I think you have to take a look at "datos_leer_info_personal".
Test the values of "nick" etc. ...

[Elmo23x]

I checked it already, I tried to give values to the QStrings after calling datos_leer_info_personal();

and all is the same...

[jacek]

Are you sure that t1, t2 and t3 are initialized before cargar_info_personal() is invoked?

[high_flyer]

Try cleaning the project an rebuild.
See if it still crashes.
If it does:
comment out datos_leer_info_personal() and try.
Then please post the code inside datos_leer_info_personal().

I would try any other function that requires a QString as input and see if it breaks the same way. My guess is it has something to do with how your QString is initialized.

Thanks to everybody. I just reinstaled QT 4 libraries and it works now. This magic of computers
