It helps to see the full code.  Also, it's often good to be able to 
construct objects without them actually doing things and have the 
activities in a separate method.

I'll guess you are using QDialog.exec() which blocks until the user 
closes the dialog.

http://doc.qt.io/qt-5/qdialog.html#exec

The .show() call doesn't block but you will have to get the result of 
the dialog via it's signals or the .result() method.

http://doc.qt.io/qt-5/qwidget.html#show
http://doc.qt.io/qt-5/qdialog.html#result

Or, perhaps you can just move the other code so it is before the .exec() 
call for the dialog?  It really depends what all you have going on.
