Maximize table cell leads to segmentation fault

abdoemr11

I have QTableWidget that gets its data from std::vector<MyCustomWidget *mywidget>
I want to make one MyCustomWidget when double clicked to take the full size of QTableWidget and return to its default size when double clicked again.
MyCustomWidget emit this signal

emit maximizationRequested(this);

to the QTableWidget
The problem is when I try to maximize the widget with the following code

    this->setRowCount(1);
    this->setColumnCount(1);
    this->setCellWidget(0,0, maxiWidget);
    this->resizeColumnsToContents();
    this->resizeRowsToContents();

All other MyCustomWidget are destroyed So When I try to access them again It leads to segmentation fault.
I want to keep my vector of MyCustomWidget intact and I shouldn't modify MyCustomWidget what your opinions are?

Use a QStackedLayout where you show your QTableWidget and another widget where you show your data when double clicked.
