That depends on how you are using the dialog.
If this is a modal dialog, i.e. one that you display using exec(), then simply add getter functions and call them after exec() to retrieve the values.
If it is a non-modal dialog, i.e. one that you display using show(), then add signals that are emitted then the values change or a signal that emits all the values when the dialog is closed.
