Eventi d’azione del dragamine

C’è un modo per rendere determinate azioni degli eventi specifiche per i clic del mouse sinistro e destro?

Sto creando un gui dragamine, quindi quando un quadrato viene fatto clic con il tasto sinistro verrà scoperto, e quando viene fatto clic con il tasto destro verrà contrassegnato.

Non ero sicuro di come verificare sintatticamente questo aspetto e non riuscivo a trovarlo sul tut.

Grazie per l’aiuto!

Ho deciso di provarlo, per provare a creare una semplice applicazione Mine Sweeper, una senza timer o reset (ancora), ma che è funzionale e utilizza sia una class di celle GUI che una class di modello non-GUI (che puo ‘ essere copiati e usati per i compiti da intro a Java).

Modifica 1: ora ha funzionalità di ripristino:

MineSweeper.java: contiene il metodo principale e avvia JFrame

import java.awt.event.*; import javax.swing.*; @SuppressWarnings("serial") public class MineSweeper { private JPanel mainPanel = new JPanel(); private MineCellGrid mineCellGrid; private JButton resetButton = new JButton("Reset"); public MineSweeper(int rows, int cols, int mineTotal) { mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.PAGE_AXIS)); mineCellGrid = new MineCellGrid(rows, cols, mineTotal); resetButton.setMnemonic(KeyEvent.VK_R); resetButton.addActionListener(new ActionListener() { public void actionPerformsd(ActionEvent e) { mineCellGrid.reset(); } }); mainPanel.add(mineCellGrid); mainPanel.add(new JSeparator()); mainPanel.add(new JPanel(){{add(resetButton);}}); } private JPanel getMainPanel() { return mainPanel; } private static void createAndShowUI() { JFrame frame = new JFrame("MineSweeper"); //frame.getContentPane().add(new MineSweeper(20, 20, 44).getMainPanel()); frame.getContentPane().add(new MineSweeper(12, 12, 13).getMainPanel()); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } public static void main(String[] args) { java.awt.EventQueue.invokeLater(new Runnable() { public void run() { createAndShowUI(); } }); } } 

MineCellGrid.java: la class che visualizza la griglia delle celle della mia e le analizza tutte insieme.

 import java.awt.GridLayout; import java.util.ArrayList; import java.util.List; import javax.swing.JPanel; @SuppressWarnings("serial") public class MineCellGrid extends JPanel { private MineCellGridModel model; private List mineCells = new ArrayList(); public MineCellGrid(final int maxRows, final int maxCols, int mineNumber) { model = new MineCellGridModel(maxRows, maxCols, mineNumber); setLayout(new GridLayout(maxRows, maxCols)); for (int row = 0; row < maxRows; row++) { for (int col = 0; col < maxCols; col++) { MineCell mineCell = new MineCell(row, col); add(mineCell); mineCells.add(mineCell); model.add(mineCell.getModel(), row, col); } } reset(); } public void reset() { model.reset(); for (MineCell mineCell : mineCells) { mineCell.reset(); } } } 

MineCellGridModel.java: il modello non GUI per MineCellGrid

 import java.beans.PropertyChangeEvent; import java.beans.PropertyChangeListener; import java.util.ArrayList; import java.util.Collections; import java.util.List; import javax.swing.JOptionPane; public class MineCellGridModel { private MineCellModel[][] cellModelGrid; private List mineList = new ArrayList(); private CellModelPropertyChangeListener cellModelPropChangeListener = new CellModelPropertyChangeListener(); private int maxRows; private int maxCols; private int mineNumber; private int buttonsRemaining; public MineCellGridModel(final int maxRows, final int maxCols, int mineNumber) { this.maxRows = maxRows; this.maxCols = maxCols; this.mineNumber = mineNumber; for (int i = 0; i < maxRows * maxCols; i++) { mineList.add((i < mineNumber) ? true : false); } cellModelGrid = new MineCellModel[maxRows][maxCols]; buttonsRemaining = (maxRows * maxCols) - mineNumber; } public void add(MineCellModel model, int row, int col) { cellModelGrid[row][col] = model; model.addPropertyChangeListener(cellModelPropChangeListener); } public void reset() { buttonsRemaining = (maxRows * maxCols) - mineNumber; // randomize the mine location Collections.shuffle(mineList); // reset the model grid and set mines for (int r = 0; r < cellModelGrid.length; r++) { for (int c = 0; c < cellModelGrid[r].length; c++) { cellModelGrid[r][c].reset(); cellModelGrid[r][c].setMined(mineList.get(r * cellModelGrid[r].length + c)); } } // advance value property of all neighbors of a mined cell for (int r = 0; r < cellModelGrid.length; r++) { for (int c = 0; c < cellModelGrid[r].length; c++) { if (cellModelGrid[r][c].isMined()) { int rMin = Math.max(r - 1, 0); int cMin = Math.max(c - 1, 0); int rMax = Math.min(r + 1, cellModelGrid.length - 1); int cMax = Math.min(c + 1, cellModelGrid[r].length - 1); for (int row2 = rMin; row2 <= rMax; row2++) { for (int col2 = cMin; col2 <= cMax; col2++) { cellModelGrid[row2][col2].incrementValue(); } } } } } } private class CellModelPropertyChangeListener implements PropertyChangeListener { public void propertyChange(PropertyChangeEvent evt) { MineCellModel model = (MineCellModel) evt.getSource(); int row = model.getRow(); int col = model.getCol(); if (evt.getPropertyName().equals(MineCellModel.BUTTON_PRESSED)) { if (cellModelGrid[row][col].isMineBlown()) { mineBlown(); } else { buttonsRemaining--; if (buttonsRemaining <= 0) { JOptionPane.showMessageDialog(null, "You've Won!!!", "Congratulations", JOptionPane.PLAIN_MESSAGE); } if (cellModelGrid[row][col].getValue() == 0) { zeroValuePress(row, col); } } } } private void mineBlown() { for (int r = 0; r < cellModelGrid.length; r++) { for (int c = 0; c < cellModelGrid[r].length; c++) { MineCellModel model = cellModelGrid[r][c]; if (model.isMined()) { model.setMineBlown(true); } } } } private void zeroValuePress(int row, int col) { int rMin = Math.max(row - 1, 0); int cMin = Math.max(col - 1, 0); int rMax = Math.min(row + 1, cellModelGrid.length - 1); int cMax = Math.min(col + 1, cellModelGrid[row].length - 1); for (int row2 = rMin; row2 <= rMax; row2++) { for (int col2 = cMin; col2 <= cMax; col2++) { cellModelGrid[row2][col2].pressedAction(); } } } } } 

MineCell.java: la class su cui ho iniziato. Utilizza la class del modello come nucleo non GUI.

Se stai usando swing allora

C’è un modo per rendere determinate azioni degli eventi specifiche per i clic del mouse sinistro e destro?

Implementare un MouseListener senza componenti. Quindi nel metodo implementato hai un object MouseEvent che ha un metodo getButton() che ti dice quale mouse è stato premuto.

L’OP ha posto la seguente domanda, ma ora l’ha rimossa.

Questo è guidato nell’altro in un evento d’azione, quando game_lost diventa vero?

È ansible aprire un JDialog per questo.

Potresti essere interessato alla class MouseEvent di java.awt.event. Qui
