SQuirreL Plugin Tutorial

I have an idea for a plugin for SQuirreL SQL client and I'd like to know how to make a plugin. My plugin will be a query builder UI which needs access to the schema model including tables, columns, primary keys, foreign keys and constraints etc.

I have searched the web for SQurreL plugin information / tutorials and I can't find much. The best I can find is on Wikipedia which is quite brief.

If you have any links, tutorials, examples or any other information on creating SQuirreL plugins, please post them here.

Thanks

Solution

Here is a class for extending a Squirrel Plugin made in Java:

public class FulltextsearchPlugin extends DefaultSessionPlugin {  
private final Analyzer analyzer = new StandardAnalyzer();  
private final String path = "c:/temp/lucene/squirrel/";  
private final IndexWriter writer = createIndexWriter();  

@Override  
public String getAuthor() {  
    return "Mike Haller";  
}  

@Override  
public String getDescriptiveName() {  
    return "Full-Text Search Plugin";  
}  

@Override  
public String getInternalName() {  
    return "fulltextsearchplugin";  
}  

@Override  
public String getVersion() {  
    return "0.0.1";  
}  

@Override  
public PluginSessionCallback sessionStarted(ISession session) {  
    // Add context menu items to the object tree's view and procedure nodes.  
    IObjectTreeAPI otApi = session.getSessionInternalFrame()  
            .getObjectTreeAPI();  
    otApi.addToPopup(DatabaseObjectType.TABLE, new FulltextsearchMenu(this,  
            session));  
    return new PluginSessionCallbackAdaptor(this);  
 }  
}

That is a code snapshot from one of the best tutorials in my view, which provides a very clear discussion with steps on how to get a plugin implemented. The material provides a good template to extend it to other cases.
