...
    bigEditor = new QTextEdit;
    bigEditor->setPlainText(QDir::currentPath ());
    bigEditor->setFont(QFont("Courier", 15, QFont::Bold));
 
    quitButton = new QPushButton(tr("&Quit"));
    quitButton->setDefault(true);
 
    moreButton = new QPushButton(tr("&More"));
    moreButton->setCheckable(true);
    moreButton->setAutoDefault(false);
 
    buttonBox = new QDialogButtonBox(Qt::Horizontal);
    buttonBox->addButton(quitButton, QDialogButtonBox::ActionRole);
    buttonBox->addButton(moreButton, QDialogButtonBox::ActionRole);
 
    connect(moreButton, SIGNAL(clicked()), this, SLOT(Visualizza()));
    connect(quitButton, SIGNAL(clicked()), this, SLOT(accept()));
 
    extension = new QWidget;
    QVBoxLayout *extensionLayout = new QVBoxLayout;
    extensionLayout->setMargin(10);
    extensionLayout->addWidget(bigEditor);
    extension->setLayout(extensionLayout);
    extension->hide();
 
    QVBoxLayout *mainLayout = new QVBoxLayout;
    mainLayout->addWidget(horizontalGroupBox);
    mainLayout->addWidget(buttonBox);
    mainLayout->addWidget(extension);
    setLayout(mainLayout);
 
....
void Dialog::Visualizza()
{
    bool stato = extension->isHidden();
    bigEditor->append( "VISUALIZZATO" );
switch (stato)
{
case true:
    extension->show();
    bigEditor->setVisible(true);
case false:
    extension->hide();

                                bigEditor->setVisible(true);
                                break;

                                printf("false the state returning:%d \n", stato);
                                extension->hide();
                                bigEditor->setVisible(false);

SOLVED, I've use a member isHidden().

with if condition.

How about just:

Code:

---

bool state = extension->isHidden();
extension->setVisible(state);
bigEditor->setVisible(state);

You don't need any conditions then.
