Hi,

Without any code it's essentially crystal ball guessing:

• Invalid pointer ?
• Memory Access Error ?
• Memory Leak ?
• Others ?

Did you run your application through a debugger ?

My code

@
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QObject::connect(ui->pushButton,SIGNAL(clicked()),this,SLOT(tabGenarate()));

}

void MainWindow::tabGenarate()
{

tab = new QWidget;

tabWidget->addTab(tab,"New");

ui->verticalLayout->addWidget(tabWidget);

}

Are you sure that your ui has a member verticalLayout ?
