Instantiate QTableWidget dynamically during runtime

[Lykurg]

matrixTable->setHorizontalHeaderItem(row, headerItem);
matrixTable->setVerticalHeaderItem(row, headerItem);

matrixTable->setHorizontalHeaderItem(row, headerItem);
matrixTable->setVerticalHeaderItem(row, headerItem);

To copy to clipboard, switch view to plain text mode 

And this is also buggy! if matrix.getRows() > matrix.getColums()

I believe the issue is somewhere else because if I delete all the instructions within updateTable, the application still crashes. But If the Coordinator doesn't call updateTable, the application runs ok...

Thank you so much for your help, I really appreciate...

Then how the Coordinator is calling the member function of MatrixDialog. Have you check the pointer?

I solved the issue finally ! It was not a Qt issue, but a pointer issue ...(shame on me) ^^
