This is a pretty simple example how to add an UserControl to an existing Report. But since the documentation isn’t talking a lot about here’s the code:
public boolean fetch() { ReportSection reportSection; ReportTextControl textControl; ; reportSection = element.design().autoDesignSpecs().addProgrammableSection(0); textControl= reportSection.addTextControl("Hello World"); textControl.fontSize(20); //do something with your UserControl reportSection.executeSection(); reportSection.delete(); //since we don't want to persist this section... return true; //true since the execution of the report should continue }
Everything you need to do is to create a new report and overwrite the method fetch() with the code above.
Have a look at the links I added to the source-code for further information.
