Dynamic width of a Textfied - with Parameter ??

[kolja.ehlersiconplc.com]

Is it possible to pass a Parameter to a Subreport to change the width of a textfield in the subreport dynamically? I know I could have maybe 10 Textfields: 50px, 100px, 150px .... and with a print when expression I could show one and hide the others. But is it not possible to change the width by parameter?

Thanks

Element widths cannot be changed via report parameters or other type of dynamic expressions.

The only way of doing this is to use the JasperReports API by change the element width before filling the report.  You would have to locate the specific JRElement instance in the JasperReport object and call setWidth on the element.  Note that you would have to do this before starting to fill the report/subreport.

I am facing the same problem of making a text element having dynamic width. Can you please post some code snippet for the solution that you are suggesting

See  below.

Code:

JasperDesign design = xmlLoader.loadXML(..jrxmlStream..);JRElement[] elements = design.getDetail().getElements();String elementKey = ..key of element to modify..;int newWidth = ..new element width..;for (int i = 0; i < elements.length; i++){	JRDesignElement element = (JRDesignElement) elements[i];	if (elementKey.equals(element.getKey()))	{		element.setWidth(newWidth);	}}

If you want to change the report page heitght and width see the JasperDesign.setPageWidth() and setPageHeight() methods.
