扫雷java程序源代码 扫雷java程序详细解析

Java扫雷程序左右键同时按下的问题

改成

int onmask = e.BUTTON1_DOWN_MASK | e.BUTTON3_DOWN_MASK;

if ((e.getModifiersEx() onmask) == onmask) {

System.out.println("ok");

}

API文档：

getModifiersEx

public int getModifiersEx()

返回此事件的扩展修饰符掩码。扩展修饰符表示所有模式键的状态，例如 ALT、CTRL、META 和事件发生后那一刻的鼠标按钮

例如，如果用户在按下 button 1 后又按下 button 2，然后以相同的顺序释放这两个哪雀按钮，则会生成以下事件迹斗序列：

MOUSE_PRESSED: BUTTON1_DOWN_MASK

MOUSE_PRESSED: BUTTON1_DOWN_MASK | BUTTON2_DOWN_MASK

MOUSE_RELEASED: BUTTON2_DOWN_MASK

MOUSE_CLICKED: BUTTON2_DOWN_MASK

MOUSE_RELEASED:

MOUSE_CLICKED:

建议不使用 == 来比较此方法的返回值，因为在以后会增加新的修饰符。例如，检查 SHIFT 和 BUTTON1 已经按下而 CTRL 未按下的正确方法可以通过以下代码来演示：

int onmask = SHIFT_DOWN_MASK | BUTTON1_DOWN_MASK;

int offmask = CTRL_DOWN_MASK;

if (event.getModifiersEx() (onmask | offmask) == onmask) {

...

}

即使姿缓磨添加了新的修饰符，上述代码仍然有效。

从以下版本开始：
