Dynamically change the fonts and color

2005-03-29 12:10

Hi,

 

I need to dynamically change the background color and font style(bold etc) of the text field depending on values returned from a List object.

 

I am using a CustomDataSource and setting the background color and font style in the xml template. I need to change some of these values dynamically.

 

Any ideas on how this can be done.

How do I obtain a handle to the JRTextField or the JRBaseTextField elements. These classes have getter and setter methods for manipulating these attributes.

 

Should I create the template design on the fly too using JasperDesign or Can this be done using scriplets?

 

Any ideas are appreciated.

 

Thanks

Check this thread. I was using iReport. But it all should apply

I'm looking for xml sample to show how styles are applied. Inline is fine. I used the following code(added the style='xx' in an attempt to overcome a SaxParse error I'm getting).:

org.xml.sax.SAXParseException: Element type "style" must be declared.

      at com.sun.org.apache.xerces.internal.impl.dtd.XMLDTDValidator.handleStartElement(XMLDTDValidator.java:1929) I've tried several variations of this with no success. Our Jasper version is 0.6.0 as we are expanding an earlier implementation. We are planning to upgrade in a separate effort.

** Code attached **Using: DOCTYPE jasperReport PUBLIC "//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">

Can we point to explicit version of the DTD? Is this necesary?
