QTabWidget close program when i change tab

[ppitu]

Hi

My problem is that when I start the program and immediately wants to change the tab, the program closes when I do something on the first tab and then change to the next one everything is fine.

Its code when i create tabwidget:

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow),
      mTabWidget(new QTabWidget(this)),
      mSummaryPaymentWidget(new SummaryPaymentWidget(this)),
      mCategoryWidget(new CategoryWidget(this)),
      mStackedWidget(new QStackedWidget(this))
{
    ui->setupUi(this);

    SummaryPaymentModel *model = new SummaryPaymentModel(this);

    mSummaryPaymentWidget->setModel(model);

    CategoryModel *categoryModel = new CategoryModel(this);

    mCategoryWidget->setModel(categoryModel);

    mTabWidget->setUpdatesEnabled(false);
    mTabWidget->addTab(mSummaryPaymentWidget, tr("Podsuwoanie wydaktów"));
    mTabWidget->addTab(mCategoryWidget, tr("Kategorie"));
    mTabWidget->setUpdatesEnabled(true);

    //mStackedWidget->addWidget(mTabWidget);


    //setCentralWidget(mStackedWidget);

    setCentralWidget(mTabWidget);
}

@ppitu So, did you at least use debugger to see where it crashes (I assume it crashes) and to get stack trace after crash?
