Examples with Event org.olat.core.gui.control.Event used on opensource projects

Example 61 with Event

use of org.olat.core.gui.control.Event in project openolat by klemens.

the class VelocityContainer method doDispatchRequest.

/**
 * @see org.olat.core.gui.components.Component#dispatchRequest(org.olat.core.gui.UserRequest)
 */
@Override
protected void doDispatchRequest(UserRequest ureq) {
    // called when a page-link is clicked ($r.renderCommand)
    String commandString = ureq.getParameter(COMMAND_ID);
    // WAS: set component dirty by default.
    // if you are in ajax mode, and the link resulted in a external mediaresource, then you can (in your controller) manually reset dirty to false.
    // we decided that there are only very few cases for this, and otherwise that the chance that a developers forgets to call vc.setDirty(true) is
    // much higher
    // now: normal links are created using the Link component, which takes care of setting dirty itself (everytime it is dispatched)
    // setDirty(true);
    // notify listening controllers
    fireEvent(ureq, new Event(commandString));
