如何在不退出整个应用程序的情况下,根据特定帧内JPanel上的模拟退出特定帧?
在我的主要课程中,我有一个Frame()方法
public void FightFrame(String offensemsg){
JFrame frame = new JFrame("BattleView: ");
frame.setLayout(new BorderLayout());
FightScene sc = new FightScene();
frame.add(sc);
frame.setVisible(true);
frame.setSize(652, 480);
frame.setLocationRelativeTo(null);
frame.setResizable(false);
sc.GenerateScene(offensemsg);
}
在我的FightScene课程中,我正在绘制一个fightscene,该类也有checkCollision()方法
public void checkCollisions() {
for (int i = 0; i < defense.size(); i++) {
FriendlyEntity m = (FriendlyEntity) defense.get(i);
Rectangle r1 = m.getBounds();
for (int j = 0; j<offense.size(); j++) {
Enemy a = (Enemy) offense.get(j);
Rectangle r2 = a.getBounds();
if (r1.intersects(r2)) {
m.setHealth(-1);
a.setHealth(-1);
if(a.getHealth()==0){
a.setVisible(false);
} else if(m.getHealth()==0){
m.setVisible(false);
}
}}
}
if(defense.size()==0){
System.out.println("You have lost the battle\n");
//############ How can I exit the FightFrame from here?
}else if (offense.size()==0){
System.out.println("You have won the battle\n");
//############# How can I exit the FightFrame from here?
}
}

将JFrame#setDefaultCloseOperation
设为JFrame.DISPOSE_ON_CLOSE
JFrame frame=new JFrame();//create frame
//so when we exit or dispose of Jframe it doesnt exit the entire app
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
...
frame.pack();
frame.setVisible(true);
现在关闭框架只需:
frame.dispose();//close the `JFrame` instance

我理解但是如何使用
FightScene()
触发这个(这是 一个JPanel)?
通过构造函数或 setter 将JFrame
的实例传递给JPanel
或
如果您不想在JPanel
类/方法中使用实例,请执行以下操作:
JFrame frame = (JFrame) SwingUtilities.getWindowAncestor(this);
frame.dispose();

((帧)FightScene.this.getTopLevelAncestor())处理(); // FightScene是JPanel
