Creating a GUI linked to a core shared library

The gallery-core shared library is now ready. Let's see how to create the desktop GUI project. We will create a Qt Widgets application sub-project called gallery-desktop. Only the first steps differ from a classic Qt Widgets application. Right-click on the main project, and select ch04-gallery-desktop | New subproject | Application | Qt Widgets Application | Choose.

HEADERS  += MainWindow.h 
 
FORMS    += MainWindow.ui
