鼠标单击无效

Question

每当点击方块时，我都会尝试从黑到白，从白到黑的方形更改颜色。我使用mouseClicked函数来执行此操作，但问题是mouseClicked未正确单击。当我点击一个方格的底部时，按下它下方的方形。

这是我的mouseClicked代码：

addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                mouseX = e.getX();
                mouseY = e.getY();
                System.out.println(mouseX + ", " + mouseY + ", " + (screenW / squares));
                colorFlip();
            }
        });

我的colorFlip代码：

private void colorFlip() {
    for (int i = 0; i < cells.size(); i++) {
        Cell cell = cells.get(i);
        int x = cell.getX();
        int y = cell.getY();
        int side = cell.getSide();
        if (mouseX >= x && mouseX < x + side && mouseY >= y && mouseY < y + side) {
            if (cell.getR() == 0) {
                cell.setRGB(255, 255, 255);
            } else if (cell.getR() == 255) {
                cell.setRGB(0, 0, 0);
            }
        }
    }
    mouseX = -1;
    mouseY = -1;
}

我的单元格初始化代码：

   Cell(double xVal, double yVal, double sideVal) {
    x = xVal;
    y = yVal;
    side = sideVal;
}

谢谢， Pranav
