Swing Overlay

이런 방식이 있다는 설명으로, 실제 사용 시에는 SwingWorker를 같이 사용해야 한다!

1. GlassPane

작성한 값 Panel을 setGlassPane(buildGlass())로 넣어주고, visible로 사용하면 된다.

보여줄 내용이 있으면 적용이 다양하게 적용 가능하다.

//생성
private JPanel buildGlass() {
    glass = new JPanel(new GridBagLayout());
    glass.setOpaque(false);
    glass.setCursor(new Cursor(Cursor.WAIT_CURSOR));
    glass.addMouseListener(new java.awt.event.MouseAdapter() {}); //뒤쪽 클릭 막기

    JLabel label = new JLabel("조회 중...");
    label.setFont(new Font(Font.SANS_SERIF, Font.BOLD, 14));
    label.setOpaque(true);
    label.setBackground(new Color(50, 50, 50));
    label.setForeground(Color.WHITE);
    label.setBorder(BorderFactory.createCompoundBorder(
        BorderFactory.createLineBorder(new Color(100, 100, 100), 1),
        BorderFactory.createEmptyBorder(12, 32, 12, 32)
    ));
    glass.add(label);

    return glass;
}

//넣기
setGlassPane(buildGlass());

//사용법
glass.setVisible(true); -> 작업이 끝나면 glass.setVisible(false);
label의 값도 변경하면서 사용하면 된다.

 

2. dialog

private void buildDialog() {
    dialog = new JDialog(this, true); // modal
    dialog.setUndecorated(true); // 타이틀바 제거
    dialog.setBackground(new Color(0, 0, 0, 0)); // 투명

    JLabel lblMsg = new JLabel("조회 중...");
    lblMsg.setFont(new Font(Font.SANS_SERIF, Font.BOLD, 14));
    lblMsg.setOpaque(true);
    lblMsg.setBackground(new Color(50, 50, 50));
    lblMsg.setForeground(Color.WHITE);
    lblMsg.setBorder(BorderFactory.createCompoundBorder(
        BorderFactory.createLineBorder(new Color(100, 100, 100), 1),
        BorderFactory.createEmptyBorder(12, 32, 12, 32)
    ));

    JPanel panel = new JPanel(new GridBagLayout());
    panel.setOpaque(false); //배경 지우기
    panel.add(lblMsg);

    dialog.setContentPane(panel);
    dialog.pack();
    dialog.setLocationRelativeTo(this);
}

//생성
//사용 시
dialog.setVisible(true) -> 작업 끝나면 dialog.dispose()
