 The goal of this tutorial is to show how we could add a new block in the detail view of a module where we could add some special functionality that we may need.
-This is basically a two step process; first we have to add the information into the database so the application knows that it has to load a new block and what code it has to launch to fill it in, then we have to implement that class to generate the output.

 To change the database we use vtlib and add a DetailViewWidget Link using vtlib:

 The initial idea is the same as above, you need a class that you reference in the DETAILVIEWWIDGET, this class returns another class that must implement a //process()// method. What we do is that this second class extends the [[https://github.com/tsolucio/corebos/blob/master/modules/Vtiger/DeveloperWidget.php#L17|class DeveloperBlock]] which gives you a set of predefined functions to help you concentrate only on the actual logic of your requirement.
-Additionally, we have modified the DEAILVIEWWIDGET code to permit you to send more parameters into your class.

 The coreBOS Question analytical module has [[https://github.com/tsolucio/corebos/blob/master/modules/cbQuestion/cbQuestionWidget.php|an example of the usage of the Developer Block]] which makes it easy to get the execution of the question into a block. Try these steps to see the result:

+==== Show IFRAME ====
+You can show an IFRAME in a block with the **showHTMLBlock**, something like this:
+<code>
+block://showHTMLBlock:modules/Utilities/showHTMLBlock.php:op=iframe&height=400px&ex=http%3A%2F%2Fcorebos.org%3Fifcrmid%3D%24RECORD%24%26ifmodule%3D%24MODULE%24
+</code>
+where you are passing to the Develop Block these parameters:
+  * **op**  =iframe (there are curently no other options)
+  * **height** string of iframe height, optional
+  * **ex** URL Encoded string with the URL to load in iframe. you can use the meta variables
+    * $RECORD$ which will be changed to CRMID of the current record if it exists
+    * $MODULE$ which will be changed to the MODULE NAME
+==== Developer Block Template ====
+This is the starting point of any developer block (the boilerplate).
