Usage

From source file:TabSample.java

static void add(JTabbedPane tabbedPane, String label) {
    int count = tabbedPane.getTabCount();
    JButton button = new JButton(label);
    button.setBackground(colors[count]);
    tabbedPane.addTab(label, new ImageIcon("yourFile.gif"), button, label);
}

From source file:Main.java

    }/*from w  ww . j a  va  2  s. co m*/
    final ByteArrayOutputStream out = new ByteArrayOutputStream();
    final byte[] buffer = new byte[1024];
    int read;
    while ((read = in.read(buffer)) > 0) {
        out.write(buffer, 0, read);
    }
    in.close();
    return new ImageIcon(out.toByteArray());
