Java项目之星际争霸1简单仿制（二）UI的实现
UI实现的难点在于Jcombobox和Jlist的选用，界面更好的跳转，点选后组合框弹跳功能的实现，修改分辨率为800X600
为了实现更好的界面跳转效果和功能选用采用了卡片布局.
先看一下UI总共的实现类别：
Abstractpanel：对属性进行一些基本的设置，比如颜色和字体，做为一个ParentPanel
ConsolePanel：是玩家主要的控制面板，如小地图和工作窗GameGUI：作为最顶层的Frame
GamePanel：游戏面板，也放置了一些控制方法，左右键的点击，用画笔画了控制线
MainMenuPanel：菜单面板
MapPanel：地图面板 注意画框有一个像素 画笔使用双缓冲 使用了MouseAdapter
MutilPlayerPanel:多人游戏界面
NetworkPanel：网络面板
NewGamePanel：新建游戏面板
ProgressPanel：进度条面板
SingleGamePanel：单人游戏面板
WorkPanel：建造面板
UI的实现采用了建立父类面板的方法来节省编码实践，提高编码效率。
下面阐述一下技术难点的处理方法
1.分辨率的修改
修改分辨率要用到java.awt包
使用其中的DisplayMode
调用isFullScreenSupported()方法返回的是false
new DisplayMode(1024,768,16,0);
修改显示器的分辨率依赖于硬件，在个别显示器中不一定好用
public void setResolution() {
GraphicsEnvironment environment = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice device=environment.getDefaultScreenDevice();
DisplayMode displayMode=new DisplayMode(1024,768,16,75);
device.setDisplayMode(displayMode);
}
public static void main(String args[]) {
FenBianLv fbl = new FenBianLv();
fbl.setResolution();
}
2.Jcombobox和Jlist的选用
JComboBox 只有一行，但是点击右边向下箭头后，有一列可以选择，至于一列可以显示多少个列对象，可以通过setMaximumRow方法设置。
JList是直接列出很多列对象可以选择。本身没有滚动条，可以添加JScrollPane对象绑定Jlist到滚动条。使用setVisibleRowCount()方法调节显示的选项数
swing默认的BasicComboBoxRenderer主要是为了改变默认选择每个下拉项的外观
3.点选功能键后发生界面跳转的弹跳功能实现
可以将基本组件的弹跳与QQ聊天窗口的抖动功能类比，其本质是短时间内基本组件发生了坐标位置的来回变换。
public void shake() {
new Thread() {
public void run() {
for (int i = 0; i < 5; i++) {
// 获取到的是原始位置
setLocation((int) getX(), (int) getY() - 5);
ThreadUtil.sleep(20);
setLocation((int) getX() - 5, (int) getY());
ThreadUtil.sleep(20);
setLocation((int) getX(), (int) getY() + 5);
ThreadUtil.sleep(20);
setLocation((int) getX() + 5, (int) getY());
ThreadUtil.sleep(20);
setLocation((int) getX(), (int) getY());
}
};
}.start();
}
下面放出代码：

map_panel.setLocation(10, 20);
work_panel.setLocation(10, 158);
add(map_panel);
add(work_panel);
gridMapRender.setConsolePanel(this);
}
