Derived class from QLineEdit is behaving differently.

[savaliya_ambani]

hi,

i have derived a class say MyLineEdit From QLineEdit as below.

classs MyLineEdit:public QLineEdit
{
 
   setFocusPolicy(Qt::OnClickFocus);
   setInputMask("000");
   setmaxLength(5);
   setStyleSheet("color:white");
}
 
 
myLineEdit *obj1;
obj1 -> setInputMask("NNNNNN"); 
connect(obj1,SIGNAL(editingFinished()),this,SLOT( printFinish()));

classs MyLineEdit:public QLineEdit
{

   setFocusPolicy(Qt::OnClickFocus);
   setInputMask("000");
   setmaxLength(5);
   setStyleSheet("color:white");
}


myLineEdit *obj1;
obj1 -> setInputMask("NNNNNN"); 
connect(obj1,SIGNAL(editingFinished()),this,SLOT( printFinish()));

To copy to clipboard, switch view to plain text mode 

But, This never comes in a printFinish() Slot.

If i dont take use, obj1 -> setInputMask("NNNNNN"); , than the things are normal and it invokes printFinish() Slot.

what is the problem in this.
