public class JavaBean
extends AbstractFontElement
implements HyperlinkProperties

An instance of this class is an i-net Clear Reports Element that represents a Java Bean which can be rendered to a report. The Java bean must be a lightweight bean extending java.awt.Component.

Use Section.addJavaBean to create a JavaBean element.

Use the setBeanProperty methods to set a bean property to a Java Object or an i-net Clear Reports ForumulaField.

There are two methods for rendering a report. The default method paintToImage paints the view of the Java bean into a background image then draws the image to the report. If paintToImage is set to false, this class will attempt to render directly to the report (which may provide better quality, e.g when using fonts). Please note that the second method does not support components that use a Java Graphics2D object to paint themselves and currently does not support clipping.

Please note that the view (image) of the bean is taken directly after the beans' paint method returns. If the bean accesses its Graphics in threads or after the paint method the resulting view will be incorrect. The following example code creates a PDF report containing a javax.swing.JSlider component showing 75% of 100%:

 Engine engine = RDC.createEmptyEngine();
 Section section = (Section) engine.getSections().get(0);
 JavaBean javaBean = section.addJavaBean("javax.swing.JSlider", 1, 100, 3000, 315);
 javaBean.setBeanProperty("minimum", new Integer(0));
 javaBean.setBeanProperty("maximum", new Integer(100));
 javaBean.setBeanProperty("value", new Integer(75));
 engine.execute();
 FileOutputStream fos = new FileOutputStream("D:/exports/slider_bean.pdf");
 for( int i=1;i<=engine.getPageCount();i++ ) {
     fos.write(engine.getPageData(i));
 }
 fos.close();
