Change focus

Suzy Q

Can somebody help me!! Why this code is working with QMessageBox::information(0, "js", "no"); but without it doesn't??????
I want to set focus from lineEdit (numCard) to a pushButton (no) with pressing enter.

bool Poeni::event(QEvent *event)
{
if (event->type() == QEvent::KeyPress)
{

    QKeyEvent* pKeyEvent=static_cast<QKeyEvent*>(event);

    switch(pKeyEvent->key())
    {

    case Qt::Key_Return:
    case Qt::Key_Enter:

if(no->hasFocus())
{

           Otkazi();
            return true;
        }
       else if(numCard->hasFocus() && numCard->text().isEmpty())
       {

         QMessageBox::information(0, "js", "no");
          no->setFocus();
           return true;
       }

break;
}

 }
 return QWidget::event(event);

}

Hi,

Here is what I would try:

Use keyPressEvent(QKeyEvent* event) instead of event(QEvent* event) because it's much simpler, and you deal with what you really need to, i.e. key events.
Use

QApplication::processEvents();

instead of

QMessageBox::information(0, "js", "no");

Try to setFocus twice in a row (I encountered some weird behavior with focus before).

Also, could you use code tag in order to format your snippet? It's quite hard to read.
