示例1: init

extender()->setEmptyExtenderMessage(i18n("No Activities..."));
// don't grow too much height
extender()->setMaximumHeight(300);
if (extender()->item("Activities") == 0) {
// create the item
Plasma::ExtenderItem *item = new Plasma::ExtenderItem(extender());
// initialize the item
initExtenderItem(item);
// set item name and title
item->setName("Activities");
