QAbstractSpinBox Subclass exhibits wierd behavour

[sunil.thaha]

Hi,

Does anyone know why this simple class exihits a wierd behavior ?

class Test : public QAbstractSpinBox {
Q_OBJECT
public:
    Test( QWidget *parent =0 ) 
        :QAbstractSpinBox(parent){
        lineEdit()->setText( "Hello " );
    }
 
    void setText( const QString &txt){
        lineEdit()->setText( txt );
    }
};

class Test : public QAbstractSpinBox {
Q_OBJECT
public:
    Test( QWidget *parent =0 ) 
        :QAbstractSpinBox(parent){
        lineEdit()->setText( "Hello " );
    }
    
    void setText( const QString &txt){
        lineEdit()->setText( txt );
    }
};

To copy to clipboard, switch view to plain text mode 

I have subclassed a QAbstractSpinBox and in the constructor I have set the SpinBox's lineedit's text to "Hello" So In the code below I expect to see the text "Hello " inside the LineEdit but It remains blank

Test t;
t.show();

Test t;
t.show();

To copy to clipboard, switch view to plain text mode 

Now I tried this, note that the setText() call after the show works, but not before it ?

Test t;
t.setText( "Before show");                // Will not work, to test it comment the setText below show
 t.show();
t.setText( "Hi Hi ");                          // Calls to setText works after show ??

Test t;
t.setText( "Before show");                // Will not work, to test it comment the setText below show
 t.show();
t.setText( "Hi Hi ");                          // Calls to setText works after show ??

To copy to clipboard, switch view to plain text mode 

Any clue why this happens?
