Get data from a QLineEdit, inside a Qt Designer for class

[aguleo]

I have a QMainWindow (w) thal creates an instance of a myDialog at a certain moment.
In the action used to manipulate this case i have:

myDialog dialog;
dialog.exec();
info = dialog.?????????

myDialog dialog;
dialog.exec();
info = dialog.?????????

To copy to clipboard, switch view to plain text mode 

I suppose that a get function is not needed to fetch some text from a lineEdit in the ui!
This is a Qt Designer Form Class (myDialog.h + myDialog.cpp + myDialog.ui).
How do i get there?
