I have a project in which I have several components, . The problem is that when the repaint () command is executed, the JLabels are not painted. I want to make it clear that it is NOT a problem that there are graphics that are being painted on or anything. Apparently what happens is that within repaint (), when I force the JLabel to repaint, they do not paint unless you change the JLabel chain.
Initialization of the JLabel and define its parameters:
puntuacionL.setFont(new Font("Marker Felt", Font.PLAIN, 20));
puntuacionL.setBounds(710, 212, 150, 30);
puntuacionL.setOpaque(true);
puntuacionL.setBackground(Color.CYAN);
puntuacionL.setForeground(Color.white);
puntuacionL.setVisible(true);
comoJugar.setFont(new Font("Marker Felt", Font.PLAIN, 20));
comoJugar.setBounds(710, 245, 150, 30);
comoJugar.setOpaque(true);
comoJugar.setBackground(Color.CYAN);
comoJugar.setForeground(Color.white);
comoJugar.setVisible(true);
I have tried two options to force the redefinition of JLabel:
1. mietiqueta.setText("whatever").
In this option what I do is to redefine in the repaint () label string.
2.
Repaint the component: mietiqueta.paintComponent(g)
I would have uploaded a capture of the result, which would have been very useful, but you need at least 10 reputation points
Repaint() method:
@Override
public void update(Graphics g){
paint(g);
}
@Override
public void paint(Graphics g) {
if (offGraphics == null) {
offImage = createImage(900,900);
offGraphics = (Graphics2D) offImage.getGraphics();
}
puntuacionL.setText(" Puntuación: "+Integer.toString(puntuacion));
comoJugar.setText(" Pulsa H para ayuda");
Graphics2D g2d = (Graphics2D) g;
puntoIncialBala();
Image fondo = new ImageIcon(getClass().getResource("/imagenes/fondo.jpeg")).getImage();
Image img2 = new ImageIcon(getClass().getResource("/imagenes/fondoMapa.png")).getImage();
offGraphics.drawImage(img2, 30, 30, this);
int posVidaX = 710;
offGraphics.setColor(Color.CYAN);
offGraphics.fillRoundRect(710, 30, 150, 100, 10, 10);
for (int k = 0; k < vidas; k++) {
Image vida = new ImageIcon(getClass().getResource("/imagenes/vida.png")).getImage();
offGraphics.drawImage(vida, posVidaX, 50, this);
posVidaX = posVidaX + vida.getWidth(this);
}
timeLabel.paintComponents(g);
for (int k = 0; k < arrayCasilla.size(); k++) {
offGraphics.drawImage(arrayCasilla.get(k).getImg(), (int) arrayCasilla.get(k).getY(), (int) arrayCasilla.get(k).getX(), this);
}
Image img = new ImageIcon(getClass().getResource("/imagenes/BalaCanon.png")).getImage();
if (flagBala == true) {
//puntuacionL.setText(" Puntuación: "+Integer.toString(puntuacion));
if (pintarCasilla == true) {
puntuacionL.setText(" Puntuación: "+Integer.toString(puntuacion));
comoJugar.setText(" Pulsa H para ayuda");
queHayCasilla();
if (casilla[x][y].getTipo().compareTo("cangrejo") == 0) {
puntuacion = puntuacion + 1;
} else if (casilla[x][y].getTipo().compareTo("ron") == 0) {
posVidaX = 710;
//puntuacion = puntuacion + 1;
vidas--;
if (vidas == 0) {
timer.stop();
etiquetaFin.setVisible(true);
finalizar.setVisible(true);
contenedorFinal.setVisible(true);
}
offGraphics.setColor(Color.CYAN);
offGraphics.fillRoundRect(710, 30, 150, 100, 10, 10);
for (int k = 0; k < vidas; k++) {
Image vida = new ImageIcon(getClass().getResource("/imagenes/vida.png")).getImage();
offGraphics.drawImage(vida, posVidaX, 50, this);
posVidaX = posVidaX + vida.getWidth(this);
}
} else if (casilla[x][y].getTipo().compareTo("cofre") == 0) {
puntuacion = puntuacion + 2;
}
if (posY[y] < 441) {
arrayCasilla.add(casilla[x][y]);
}
for (int k = 0; k < arrayCasilla.size(); k++) {
if (posY[y] < 441) {
offGraphics.drawImage(arrayCasilla.get(k).getImg(), (int) arrayCasilla.get(k).getY(), (int) arrayCasilla.get(k).getX(), this);
}
}
animacion.stop();
if (!animacion.isRunning()) {
i = 0;
}
pintarCasilla = false;
flagBala = false;
} else {
offGraphics.drawImage(img, (int) x1, (int) x2, this);
}
}
try {
imgB = ImageIO.read(getClass().getResource("/imagenes/canon.png"));
} catch (IOException ex) {
Logger.getLogger(PanelCanon.class.getName()).log(Level.SEVERE, null, ex);
}
offGraphics.setColor(Color.gray);
offGraphics.fillRect(30, 720, 646, 122);
AffineTransform tx = AffineTransform.getRotateInstance(Math.PI / 2 - anguloRotacion, imgB.getWidth(this) / 2, imgB.getHeight(this) / 2);
AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_BILINEAR);
tx.rotate(Math.PI / 2 - anguloRotacion);
System.out.println(tx.toString());
offGraphics.drawImage(op.filter(imgB, null), 360, 740, null);
g2d.drawImage(offImage, 0, 0, this);
puntuacionL.setText(" Puntuación: "+Integer.toString(puntuacion));
comoJugar.setText(" Pulsa H para ayuda");
System.out.println("Posicion bala x" + x1);
System.out.println("Posicion bala y: " + x2);
}
I have a timer that may be interfering in some way, this timer is responsible for controlling the countdown.
Timer code:
timer = new Timer(1000, new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
if (seconds == 0 && minutes == 0) {
timer.stop();
etiquetaFin.setVisible(true);
finalizar.setVisible(true);
contenedorFinal.setVisible(true);
} else if (seconds > 0) {
seconds--;
} else if (minutes > 0) {
minutes--;
seconds = 59;
}
revalidate();
//puntuacionL.paintImmediately(710, 212, 150, 30);
//puntuacionL.setText(" Puntuación: "+Integer.toString(puntuacion));
//comoJugar.setText(" Pulsa H para ayuda");
timeLabel.setText(" "+timeFormatter.format(minutes) + ":" + timeFormatter.format(seconds));
}
});
timer.start();
And this is where the magic happens and I do not understand anything anymore. As you can see inside the event I have commented the lines:
puntuacionL.setText(" Puntuación: "+Integer.toString(puntuacion));
comoJugar.setText(" Pulsa H para ayuda");
If within the event of the Timer I redefine the Labels, with a different string from the paint () they are painted, but of course it does not work for me, since I want the string not to be modified.
I have not put the whole class because it is quite large, but if someone still needs the complete context, happy to edit the question and put all the code.
