Hi Sushant,
BIRT already has a number of events that you can override for server-side processing of the report... Are you looking to write code against a server event... or client event?

Hi Virgil,
I am actually looking at adding events in addition to the available events in BIRT which gets executed when the report is run be it from the BIRT RCP or when i deploy it on the Application server.

Thanks and Regards

Hi Sushant,

There are several places where you can call your custom Java and Javascript code. Can you give me an idea of the type of custom event you would like to create?

Since this sounds like you are trying to add Client side events, then Javascript is what you should use. For a BIRT report rendered in the browser, you can add a Text Control, select HTML for formatting, and then use a script like below.

<script language="javascript">
if (document.layers) { document.captureEvents(Event.KEYPRESS); }
document.onkeypress = getKey;
function getKey(keyStroke) {
var keyCode = (document.layers) ? keyStroke.which : event.keyCode;
var keyString = String.fromCharCode(keyCode).toLowerCase();
alert("keyCode="+keyCode+" keyString="+keyString);
}
</script>

When added to a BIRT report, this script will detect the keystroke of the user and display that they have typed.

Thanks. Now i will be able to track the key stroke events.
