我想在Swing应用程序中嵌入第三方applet.基本上,我希望它只是另一个小组.该applet使用许多参数,例如
final String config_filename = getParameter(XXX);
解决方法
实现AppletStub&将其设置为applet实例的存根.例如.
/*
<applet code='ParamApplet' width='200' height='200'>
<param name='param' value='foo'>
</applet>
*/
import java.applet.*;
import javax.swing.*;
import java.net.URL;
import java.util.HashMap;
public class ParamApplet extends JApplet {
public void init() {
String param = getParameter("param");
System.out.println("parameter: " + param);
add(new JLabel(param));
}
public static void main(String[] args) {
ApplicationAppletStub stub = new ApplicationAppletStub();
stub.addParameter(args[0],args[1]);
ParamApplet pa = new ParamApplet();
pa.setStub(stub);
pa.init();
pa.start();
pa.setPreferredSize(new java.awt.Dimension(200,200));
JOptionPane.showMessageDialog(null,pa);
}
}
class ApplicationAppletStub implements AppletStub {
HashMap<String,String> params = new HashMap<String,String>();
public void appletResize(int width,int height) {}
public AppletContext getAppletContext() {
return null;
}
public URL getDocumentBase() {
return null;
}
public URL getCodeBase() {
return null;
}
public boolean isActive() {
return true;
}
public String getParameter(String name) {
return params.get(name);
}
public void addParameter(String name,String value) {
params.put(name,value);
}
}
典型的I / O.
prompt>java ParamApplet param "apples & oranges" parameter: apples & oranges prompt>java ParamApplet param 42 parameter: 42 prompt>
