Alternate Color On Group Rows (BIRT)

< To: Report Developer Examples (BIRT)
This example is Bugzilla ID 212627. If you would like to contribute an example see the example contribution guidelines.

Introduction

This illustrates using highlight rules to alternate the backgroundColor of the row that displays header data. In some reports, there is no detail information. All of the information is contained in the group headers. For clarity, it is nice to have the group headers alternate colors. This example shows how to do that.

BIRT Version Compatibility

This example was built and tested with BIRT 2.2.1.1.

Description

In order to make this work, you need to alternate the value of a global variable. This is best done in the OnCreate method of the table row that is showing the Group information.

if (reportContext.getGlobalVariable("alt_grp") == false)
    reportContext.setGlobalVariable("alt_grp", true);
else
    reportContext.setGlobalVariable("alt_grp", false);

Then all you need to do is add a highlight rule on the row. In the If following condition field enter

reportContext.getGlobalVariable("alt_grp")

And in the condition drop-down select "is true". Then just apply the format rules you would like for the alternate groups.
