Add an application icon when inheritance comes from org.jdesktop.application.FrameView

If you are using Netbeans to generate your components and if you have the next type of constructor


public Main(SingleFrameApplication app)
{
initComponents();
}



just add the next code after calling initComponents

java.awt.Image im = java.awt.Toolkit.getDefaultToolkit().getImage(getClass().getResource("/com/.../feed-icon.png"));
getFrame().setIconImage(im);


(Of course correct the path to the file inside the package.)

Now your application should display the icon in the top of the window (only tested in Microsoft Windows)
