Hi ,

I have been through the Help file content of the Birt Designer ( 45 Days trial version) installed .I would like to more about scripting in birt report.

If there is any other place where i can get informnation which can help me in starting the birt scripting

1) information on basic scripting and reffering different components of report and accessing different components .

2) basic functions and classes provided by BIRt for scripting which we can make use in report

a small description to add here is ...if i have to fetch value of one colum and display on some condition .
which can be a mouse click or mouse hover .In this scenario how can i bind the required column and fetch data .

It will be helpful if a document with examples can be provided so that i can have a fair idea about BIRT scripting.

Thanks
Priya

Maybe these links will help you some:

Scripting methods in BIRT and some example script:

http://www.eclipse.org/birt/phoenix/deploy/reportScripting.php

BIRT 2.3 documentation:

http://www.birt-exchange.com/be/downloads/documentation/#actuate10docs

Also, you can always ask questions in the forums on how to do specific things if you can't find anything after a brief search!

Hope this helps.

Scripting in BIRT is best understood by learning the BIRT API's. To do most tasks in BIRT scripting you basically need to understand 2 things:

1: Report GEneration Lifecycle
2: Report Structure

You can learn a good bit about the report lifecycle by learning about the Report Engine API. There is tons of documentation about this, and if you search on the EclipseCon site for previous years there are plenty of material posted by Jason Weathersby, Michael Williams, and myself about working with the REAPI. The biggest thing to take away from this is the flow chart of the generation process because it pretty much sums up what each event is in the scripting environment and what is available.

In terms of learning about report structure, you can do research on the Design Engine API. This covers how to build or modify BIRT reports pragmatically. Again, the DevShare here on BIRT Exchange and the EclipseCon websites for previous years will be your best friends.

If your looking for good reference material, I recommend Integrating and Extending BIRT by Jason Weathersby. It will be a pretty complete reference source on the topic.

I am currently designing a report with birt 2.2 and I want to make a script for the cross tab elements that I created. The trouble is that when I click on them in the script tab it says "This element has no methods." I found <a class='bbc_url' href='http://birtworld.blogspot.com/2010/02/birt-crosstab-scripting.html'>this page</a>, but I can't seem to recreate what he has done since I can't write the script where he did. Or maybe am I looking in the wrong place? Where you you put this script?

Crosstab's did not have any scripting methods until BIRT 2.3.1. To gain access to those script areas, you'll need to upgrade.
