私は、矢印とノードを含むグラフ魔女を描かなければならなかったプロジェクトで働いています! JPanel矢印とノードを拡張するクラスをJSplitPane 作成し、左にメニュー、右にグラフを作成するクラスを作成しました。両方のパネルを追加すると、そのうちの 1 つだけが表示されます。

矢印パネル クラス:

public class ArrowPanel extends JPanel{
int barb;
double phi;
double x1;
double y1;
double x2;
double y2;
double xcentre;
double ycentre;
double x3;
double y3;
double x4;
double y4;

public ArrowPanel(double x1,double y1,double x2, double y2 ,double x3,double y3 ,double x4 ,double y4){
    barb = 30;                   // barb length
    phi = Math.PI/6;             // 30 degrees barb angle
    this.x1=x1;
    this.y1=y1;
    this.x2=x2;
    this.y2=y2;
    this.x3=x3;
    this.y3=y3;
    this.x4=x4;
    this.y4=y4;
    this.setVisible(true);
    this.setOpaque(false)   ;     
        this.setLayout(new GridBagLayout());
        System.out.println(" c est marché");} protected void paintComponent(Graphics g){
    super.paintComponent(g);
    Graphics2D g2 = (Graphics2D)g;
    Graphics2D g3 = (Graphics2D)g;
    g2.setStroke(new BasicStroke(7));
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                        RenderingHints.VALUE_ANTIALIAS_ON);
    g3.setStroke(new BasicStroke(7));
    g3.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);
    int w = getWidth();
    int h = getHeight();
    double theta, x, y;
    double a = 0;
        double b = 0;
        xcentre=(x1 + x2)/2 ;
        ycentre=(y1 + y2)/2 ;
        double z3 = x1;
        double k3 = y1;
        k3=a*z3+b;
        a=(y2-y1)/(x2-x1);
        b=y1-a*x1;
        System.out.println( "a="+ a);
    System.out.println( "b="+ b);
    double a1 = -1/a;
    double b1 = ycentre-a1*xcentre;


    g2.setPaint(Color.RED);
    g3.setPaint(Color.RED);
    g3.draw(new Line2D.Double(x3, y3, x4, y4));
    g2.draw(new Line2D.Double(x1, y1, x2, y2));
    theta = Math.atan2(y2 - y1, x2 - x1);
    double theta2=Math.atan2(y4 - y3, x4 - x3);
    drawArrow(g2, theta, x2, y2);
    drawArrow(g3, theta2, x4, y4);
    g2.setPaint(Color.GREEN);
    g2.draw(new Line2D.Double(xcentre - 5, a*(xcentre - 5)+ b, xcentre+5, a*(xcentre+5)+b));
    g2.drawString("rad1", getX(), getY());
    g2.draw(new Line2D.Double(xcentre - 7, a1*(xcentre - 7)+ b1, xcentre+7, a1*(xcentre+7)+b1));
    xcentre=(x3 + x4)/2 ;
    ycentre=(y3 + y4)/2 ;

         z3 = x3;
         k3 = y3;
        k3=a*z3+b;
        a=(y4-y3)/(x4-x3);
        b=y3-a*x3;
        System.out.println( "a="+ a);
    System.out.println( "b="+ b);
    a1 = -1/a;
    b1 = ycentre-a1*xcentre;
    g3.draw(new Line2D.Double(xcentre - 5, a*(xcentre - 5)+ b, xcentre+5, a*(xcentre+5)+b));
    g3.draw(new Line2D.Double(xcentre - 7, a1*(xcentre - 7)+ b1, xcentre+7, a1*(xcentre+7)+b1));
        System.out.println("bahamas");

}
private void drawArrow(Graphics2D g2, double theta, double x0, double y0)
{
    double x = x0 - barb * Math.cos(theta + phi);
    double y = y0 - barb * Math.sin(theta + phi);
    g2.draw(new Line2D.Double(x0, y0, x, y));
    x = x0 - barb * Math.cos(theta - phi);
    y = y0 - barb * Math.sin(theta - phi);
    g2.draw(new Line2D.Double(x0, y0, x, y));
}}`

これは要素クラスです:

public class ElementMenu extends JPanel {private static final long serialVersionUID = 1L;private int largeur;
private Color couleur;
private Color couleurActif;
private Color couleurNormal;
private String texte;
private String Ident;
public ElementMenu(String texte,String Ident, Color couleurNormal, Color couleurActif, int taille) {
    this.couleur=couleurNormal;
    this.couleurNormal=couleurNormal;
    this.couleurActif=couleurActif;
    this.texte=texte;
    this.Ident=Ident ;
    largeur=taille;
    this.setSize(new Dimension(largeur, largeur ));
    this.setOpaque(false);
    this.setLayout(new BorderLayout());
    ajouterListener();
}
private void ajouterListener(){
    addMouseListener(new MouseListener() {public void mouseClicked(MouseEvent e) {}

        public void mouseReleased(MouseEvent e) {}

        public void mousePressed(MouseEvent e) {}

        public void mouseExited(MouseEvent e) {
            couleur=couleurNormal;
            repaint();
        }

        public void mouseEntered(MouseEvent e) {
            couleur=couleurActif;
            setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
            repaint();
        }

    });}public void paint(Graphics arg0) {
    super.paint(arg0);
    Graphics2D g2d = (Graphics2D) arg0;
    g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setColor(couleur);
    g2d.setStroke(new BasicStroke(3));
    GradientPaint gradient = new GradientPaint(largeur / 2, 4, couleur, (largeur) / 2, 4 + largeur, new Color(255,255,255,200));
    g2d.setPaint(gradient);
    g2d.fillOval(4, 4, largeur, largeur);
    gradient = new GradientPaint(largeur / 2, 4, Color.RED, largeur / 2, 4 + largeur / 2, new Color(couleur.getRed(), couleur.getGreen(), couleur.getBlue(), 0));
    g2d.setPaint(gradient);
    g2d.fillOval(4+largeur/5, 4, 5*largeur/8, largeur/3);
    g2d.setColor(Color.WHITE);
    g2d.setFont(new Font("Calibri", Font.BOLD, 14));
    FontMetrics fm = g2d.getFontMetrics();
    int x = 10;
    int y = (fm.getAscent() + (this.getHeight() -
            (fm.getAscent() + fm.getDescent())) / 2 );
    int x0 = (this.getWidth() - fm.stringWidth(Ident)) / 4 +25;
    int y0 = (fm.getAscent() + (this.getHeight() -
            (fm.getAscent() + fm.getDescent())) / 2 -55);
    g2d.drawString(texte, x+15, y);
    g2d.drawString(Ident, x0, y0);}}`

そして、これがメインです：

public static void main(String[] args) {
    Fenetre splitPaneTest1 = new Fenetre();
    splitPaneTest1.setSize(1000,600);
    splitPaneTest1.show();
    List<ElementMenu> items = new ArrayList<ElementMenu>();
    items.add(new ElementMenu("rad1","ACTION", new Color(19, 73, 140), new Color(162, 198, 232), 150));
    items.add(new ElementMenu("rad2","GOAL",new Color(19, 73, 140), new Color(162, 198, 232), 150));
    items.add(new ElementMenu("rad3","KNOWLEDGE", new Color(19, 73, 140), new Color(162, 198, 232), 150));
    splitPaneTest1.getContentPane().add(jSplitPane1, BorderLayout.CENTER);
    jSplitPane1.setOpaque(false);
    jSplitPane1.add(new MenuCirculaire(Color.blue, 800, 600, 200, 150,items),JSplitPane.RIGHT);
    jSplitPane1.add(new ArrowPanel(363.5,335,460.5,168,540,171,635.5,335),JSplitPane.RIGHT);
    jSplitPane1.add(new MenuGauche(),JSplitPane.LEFT);
}

JSplitPaneこのようには機能しません。各分割セクションで表示できるコンポーネントは 1 つだけです。

右側のコンポーネントを両方含む別のパネルを作成する必要があります。これは次のようになります。

JPanel rightPanel = new JPanel(new GridLayout(2, 1));
rightPanel.add(monMenuCirculaire); 
rightPanel.add(monArrowPanel);
jSplitPane1.add(rightPanel, JSplitPane.RIGHT);
