Example 4 with ComponentRenderer

use of org.olat.core.gui.components.ComponentRenderer in project OpenOLAT by OpenOLAT.

the class Renderer method renderBodyOnLoadJSFunctionCall.

/**
 * renders the HTMLHeader-Part which this component comp needs. e.g. the
 * richtext component needs some css and javascript libraries an
 * velocity-container is a special case: it should collect the information
 * from all the children that are visible since all could be renderer. since
 * the actual rendering of a component depends on the page and is not know
 * beforehand, we could include some css/js which turns out not to be needed
 * in this request, but it is cached by the browser anyway, so it should not
 * matter to much. a little advice if you want to do it perfectly : program
 * the controller in such a way that they make a component invisible if not
 * needed
 *
 * @param sb
 * @param source
 * @see org.olat.core.gui.render.ui.ComponentRenderer
