Java Game Development(2)- Restoring Screen Size

import java.awt.*;

public class Screen {

private GraphicsDevice vc; → 這對象把圖形到屏幕

public Screen(){

GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();

vc = env.getDefaultScreenDevice(); → 把所有圖形元素到屏幕上

if(dm != null && vc.isDisplayChangeSupported()){ → 使屏幕能夠更改

try{

vc.setDisplayMode(dm);

}catch(Exception e){}

}

}

public void setFullScreen(DisplayMode dm,Frame window){ → dm=設置屏幕

window.setUndecorated(true); → 簡單的Frame（沒有滾動條...）

window.setResizable(false);

vc.setFullScreenWindow(window); → 設置全屏顯示

}

public Window getFullScreenWindow(){ → 全屏顯示

return vc.getFullScreenWindow();

}

public void restoreScreen(){ → 重置屏幕顯示

Window w = vc.getFullScreenWindow();

if(w != null){

w.dispose(); → 釋放內存，並重新設置

}

vc.setFullScreenWindow(null);

}

}
