    GalleryPanel gallery = new GalleryPanel();


    gbConstraints.gridx = 0;
    gbConstraints.gridy = 0;
    gbConstraints.weightx = 0.8;
    gbConstraints.weighty = 0.75;
    gbConstraints.fill=gbConstraints.BOTH;
    add(display,gbConstraints);

    gbConstraints.gridx = 1;
    gbConstraints.gridy = 0;
    gbConstraints.weightx = 0.2;
    gbConstraints.weighty = 0.75;
    gbConstraints.fill=gbConstraints.BOTH; …
