I have created a Qt application. Now I want to make an install package and release it (using LGPL).

Can I just add the qt-license.txt file to the installation directory? or I have to show the information in my application using "About Qt" QMessagebox or some other way?

Another question, What is it meant by "Make a Qt source code copy available for customer"?

Do I have to share the source code of my Qt Application?
