Unexplained Segmentation Fault with QDialog::show() and QDialog::exec()

[mcosta]

Thank you for your ideas.

1) & 4) The reason I emit a signal on accept() is because I need to get the index of the spinbox that was selected. If there's a better way to do this, let me know!

2) Why would this be a bad thing? I need to free the memory before the dialog ceases to exist, right?

2) When a QObject are destroyed, it delete all children. You have not need to delete them explicitly

For the 1) I suggest you to define a difficulty() public methods that returns m_difficulty and call it after exec from calling code

// For modal Dialog (exec()) you can use a stack variable
GenerateNewDialog dlg(this);
 
if (QDialog::Accepted == generateNewDialog.exec()) {
    difficulty = dlg.difficulty();
}

// For modal Dialog (exec()) you can use a stack variable
GenerateNewDialog dlg(this);

if (QDialog::Accepted == generateNewDialog.exec()) {
    difficulty = dlg.difficulty();
}
