swing桌面应用程序内部某个区域的java路线图？
我尝试创建Java Swing桌面应用程序，在JFrame中显示某个区域的路线图。 但电脑没有连接到互联网，它将在局域网内。 地图应该是这样的，如果我们滚动鼠标，我们从地图的高度往下走。比如放大这个区域
我试图通过谷歌找到我得到的很多论坛链接，但每一个都显示了我
- 我必须做网络应用
- 谷歌不支持“没有互联网”的地图功能
- 我应该使用很多JPG，它们存储在文件夹中，用于显示不同高度的地图，这样我们在Google Earth应用程序中看到任何地图时都会像这样
我找到了goworldwind。但目前还不清楚
你知道我该怎么做吗
您好，我们使用下面的程序在jxbrowser中显示地图
package dummy;
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.WindowConstants;
import com.teamdev.jxbrowser.chromium.Browser;
import com.teamdev.jxbrowser.chromium.BrowserFactory;
public class GoogleMapDemo {
public static final int MIN_ZOOM = 0;
public static final int MAX_ZOOM = 21;
private static int zoomValue = 4;
public static void main(String[] args) {
final Browser browser = BrowserFactory.create();
JButton zoomInButton = new JButton("Zoom In");
zoomInButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (zoomValue < MAX_ZOOM) {
browser.executeJavaScript("map.setZoom(" + ++zoomValue + ")");
}
}
});
JButton zoomOutButton = new JButton("Zoom Out");
zoomOutButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (zoomValue > MIN_ZOOM) {
browser.executeJavaScript("map.setZoom(" + --zoomValue + ")");
}
}
});
JPanel toolBar = new JPanel();
toolBar.add(zoomInButton);
toolBar.add(zoomOutButton);
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(browser.getView().getComponent(), BorderLayout.CENTER);
frame.add(toolBar, BorderLayout.NORTH);
frame.setSize(700, 500);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
browser.loadURL("/home/StaticMapDemo/map.html");
//browser.loadURL("http://www.google.com");
}
}
I have map.html file

};
map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
