JPanel revalidate and repaint not working properly (Java Swing)
I am creating a Sudoku game. The game has some buttons such as new game, re-start, solve, etc.
public void inicio() {
JPanel panel = new JPanel();
panel.setLayout(null);
panel.setPreferredSize(new Dimension(735, 620));
...
button2 = new JButton("New Game"); //Other buttons like this one
...
JPanel sudoku = PanelSudoku();
sudoku.setBounds(228, 90, 470, 470);
...
//Botón nuevo juego
button2.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
///AQUÍ CÓDIGO
setGame();
panel.remove(sudoku);
JPanel sudokuNuevo = PanelSudoku();
sudokuNuevo.setBounds(228, 90, 470, 470);
panel.add(sudokuNuevo);
panel.revalidate();
panel.repaint();
///
}
});
//Botón reiniciar juego
button3.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
///AQUÍ CÓDIGO
panel.remove(sudoku);
JPanel sudokuNuevo = PanelSudoku();
sudokuNuevo.setBounds(228, 90, 470, 470);
panel.add(sudokuNuevo);
panel.revalidate();
panel.repaint();
///
}
});
//Botón Comprobar
button4.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
///AQUÍ CÓDIGO
SwingUtilities.invokeLater(new Runnable() {
public void run() {
VentanaKeepTrying ejecutable = new VentanaKeepTrying();
//VentanaWinner ejecutable = new VentanaWinner();
ejecutable.setVisible(true);
}
});
///
}
});
//Botón resolver
button5.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
///AQUÍ CÓDIGO
SwingUtilities.invokeLater(new Runnable() {
public void run() {
panel.remove(sudoku);
JPanel sudokuNuevo = PanelSudokuResuelto();
sudokuNuevo.setBounds(228, 90, 470, 470);
panel.add(sudokuNuevo);
panel.revalidate();
panel.repaint();
}
});
///
}
...
//Agregar elementos al panel
panel.add(imagenSudoku);
panel.add(imagenMenu);
panel.add(combo1);
panel.add(button2);
panel.add(button3);
panel.add(button4);
panel.add(button5);
panel.add(button6);
panel.add(button7);
panel.add(button8);

//panelSudoku.setBackground(Color.WHITE);
//Espacio en el borde
panelSudoku.setBorder(BorderFactory.createEmptyBorder(8, 8, 8, 8));
//Número de filas, columnas, espacio horizontal, espacio vertical.

//Llenar Sudoku con Array del Nível

});
}

//Poner el número
textPane.setText((b1.get(i)));

if (i == 0 || i == 1 || i == 2 || i == 9 || i == 10 || i == 11 || i == 18 || i == 19 || i == 20 || i == 6 || i == 7 || i == 8 || i == 15 || i == 16 || i == 17 || i == 24 || i == 25 || i == 26 || i == 30 || i == 31 || i == 32 || i == 39 || i == 40 || i == 41 || i == 48 || i == 49 || i == 50 || i == 54 || i == 55 || i == 56 || i == 63 || i == 64 || i == 65 || i == 72 || i == 73 || i == 74 || i == 60 || i == 61 || i == 62 || i == 69 || i == 70 || i == 71 || i == 78 || i == 79 || i == 80) {
Color colore = new Color(224, 235, 250);
textPane.setBackground(colore);
}
//Estilos - Centrar y Colores de letra
StyledDocument doc = textPane.getStyledDocument();
SimpleAttributeSet center = new SimpleAttributeSet();
StyleConstants.setAlignment(center, StyleConstants.ALIGN_CENTER);
StyleConstants.setForeground(center, Color.darkGray);
doc.setParagraphAttributes(0, doc.getLength(), center, false);
//Agregar al panel
panelSudoku.add(textPane);
}
}
//Agregar panel
panel.add(panelSudoku);
add(panel);
//Lo regresa para poderlo útilizar
return panel;
}
The problem that I am having is that when I press, let's say the solve button and then the new game button, the new game that appears gets all funny and doesn't work as it should.
I'm just learning JavaSwing, so any help would be greatly appreciated! :)

I think it is because actually you're not removing a JPanel with previously used sudoku board, before adding another one. Try:
panel.remove(sudoku);
sudoku = PanelSudoku();
panel.add(sudoku);
panel.revalidate();
panel.repaint();
Right now you add new sudokuNuevo on a top of another.
