qpushbutton setfocus signal

[jacek]

when i press the enter in the doublespinbox, the okButton get the focus and automatically it is clicked.

Only "default" buttons react to return/enter and they disregard the focus in that matter.

Try this:

...
   connect(testButton, SIGNAL(clicked()), SLOT(testButtonPressed()));
   connect(spinBox, SIGNAL(editingFinished()), SLOT(testing()));
   connect(emitButton, SIGNAL(clicked()), SLOT(messageLaunch()));
 
   emitButton->installEventFilter( this );
   emitButton->setAutoDefault( false );
   emitButton->setDefault( false );
 
   testButton->installEventFilter( this );
   testButton->setAutoDefault( false );
   testButton->setDefault( false );
}
 
bool TestDlg::eventFilter( QObject * o, QEvent * e )
{
   QPushButton * b = qobject_cast< QPushButton * >( o );
   if( b != 0 && e->type() == QEvent::KeyPress ) {
      QKeyEvent * ke = static_cast< QKeyEvent * >( e );
      if( ke->key() == Qt::Key_Enter || ke->key() == Qt::Key_Return ) {
         b->animateClick();
         return true;
      }
   }
   return false;
}

...
   connect(testButton, SIGNAL(clicked()), SLOT(testButtonPressed()));
   connect(spinBox, SIGNAL(editingFinished()), SLOT(testing()));
   connect(emitButton, SIGNAL(clicked()), SLOT(messageLaunch()));

   emitButton->installEventFilter( this );
   emitButton->setAutoDefault( false );
   emitButton->setDefault( false );

   testButton->installEventFilter( this );
   testButton->setAutoDefault( false );
   testButton->setDefault( false );
}

bool TestDlg::eventFilter( QObject * o, QEvent * e )
{
   QPushButton * b = qobject_cast< QPushButton * >( o );
   if( b != 0 && e->type() == QEvent::KeyPress ) {
      QKeyEvent * ke = static_cast< QKeyEvent * >( e );
      if( ke->key() == Qt::Key_Enter || ke->key() == Qt::Key_Return ) {
         b->animateClick();
         return true;
      }
   }
   return false;
}
