    <p>Depends on <em>what</em> you want to inherit. I find that if I use the JavaScript prototype for object “definitions” I get the static methods of Java objects only:</p> <pre><code>function test() { this.hello = function() { for(var i in this) { println(i); } }; } test.prototype= com.acme.app.TestClass; // use your class with static methods // see the inheritance in action: var testInstance=new test(); test.hello(); </code></pre> <p>However, JavaScript allows you to do prototype assignments on object instances as well, so you could use a function like this, and get a more Java-like inheritance behaviour:</p> <pre><code>function test(baseInstance) { var obj = new function() { this.hello=function() { for(var i in this) { println(i); } }; }; obj.prototype=baseInstance; // inherit from baseInstance. } // see the thing in action: var testInstance=test(new com.acme.TestClass()); // provide your base type testInstance.hello(); </code></pre> <p>Or use a function (e.g. <code>init</code>) similar to the above function in the object itself:</p> <pre><code>function test() { this.init=function(baseInstance) { this.prototype=baseInstance; }; this.hello=function() { for(var i in this) { println(i); } }; } var testInstance=new test(); println(typeof(testInstance.prototype)); // is null or undefined testInstance.init(new com.acme.TestClass()); // inherit from base object // see it in action: println(typeof(testInstance.prototype)); // is now com.acme.TestClass testInstance.hello(); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
