Question

Is there a way to make certain event actions specific to left and right mouse clicks?

I’m creating a minesweeper gui, so when a square is left-clicked it will be uncovered, & when it’s right-clicked it will be flagged.

I wasn’t sure how to syntactically check for this & couldn’t find it on the tut.

Thanks for the help!

Answer 1

I decided to give it a go, to try to create a simple Mine Sweeper application, one without a timer or reset (yet), but that is functional and uses both a GUI cell class and a non-GUI model class (it can’t be copied and used in for intro to Java homework).

Edit 1: now has reset capability:

MineSweeper.java: holds the main method and starts the JFrame

      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 actionPerformed(ActionEvent e) {
            mineCellGrid.reset();
         }
      });

      mainPanel.add(mineCellGrid);
      mainPanel.add(new JSeparator());

            model.add(mineCell.getModel(), row, col);
         }
      }

      reset();
   }
