Modifying static element in runtime

[iperdomo]

Hi all,

 

I have a template (template.jrxml) and I want to modify static element (a line) in runtime.

 

My problem: the page width is increased/decreased based on the number of columns that I want to show in my report. Everything is working fine, but the line in my header band, if the page width grows more than the line's defined width, I got a ugly blank space in the header.

 

Is possible with JasperDesign class access the line element and modify the width on runtime? If is possible how can i do it? If not, do you have a workaround?

 

Best Regards,

 

In advance,

 

Iván

I have done something like this.

 

Here is a snippet where I did something similar (I just ripped this out of some other code so not all the variables are defined but I think you can get the picture):

Code:

File sourceFile = new File(filePath);
		JasperReport jasperReport = null;
		try {
			jasperReport = (JasperReport)JRLoader.loadObject(sourceFile);
			JRFrame data_frame = (JRFrame)jasperReport.getTitle().getElementByKey("data_frame-2"«»);
			data_frame.setX(level * 10);
			}
		} catch (JRException e) {
		  log.error(e);
		}
		return jasperReport;

 

Let me know if you have any questions.

Hi lshannon,

 

You point me in the right direction.

 

I'm now using JRDesignLine and the getElementByKey() to set the width.

 

Thanks a lot!!

 

Best Regards,
