This documentation is for an older version of ZK. For the latest one, please click here.
| self | org.zkoss.zk.ui.Component | The component itself. |
| spaceOwner | org.zkoss.zk.ui.IdSpace | The space owner of this component. It is the same as self.spaceOwner. |
| page | org.zkoss.zk.ui.Page | The page. It is the same as self.page. |
| desktop | org.zkoss.zk.ui.Desktop | The desktop. It is the same as self.desktop. |
| execution | org.zkoss.zk.ui.Execution | The current execution. |
| session | org.zkoss.zk.ui.Session | The session. |
| application | org.zkoss.zk.ui.WebApp | The Web application. |
| componentScope | java.util.Map | A map of attributes defined in the component. It is the same as the getAttributes method in the org.zkoss.zk.ui.Component interface. |
| spaceScope | java.util.Map | A map of attributes defined in the ID space containing this component. |
| pageScope | java.util.Map | A map of attributes defined in the page. It is the same as the getAttributes method in the org.zkoss.zk.ui.Page interface. |
| desktopScope | java.util.Map | A map of attributes defined in the desktop. It is the same as the getAttributes method in the org.zkoss.zk.ui.Desktop interface. |
| sessionScope | java.util.Map | A map of attributes defined in the session. It is the same as the getAttributes method in the org.zkoss.zk.ui.Session interface. |
| applicationScope | java.util.Map | A map of attributes defined in the web application. It is the same as the getAttributes method in the org.zkoss.zk.ui.WebApp interface. |
| requestScope | java.util.Map | A map of attributes defined in the request. It is the same as the getAttributes method in the org.zkoss.zk.ui.Execution interface. |
| param | java.util.Map | A map of attributes passed by the query string. Please refer to section Pass Values to the Included Page for example. |
| arg | java.util.Map | The arg argument passed to the createComponents method in the org.zkoss.zk.ui.Executions class. It is never null.
It is the same as self.desktop.execution.arg. Notice that arg is available only when creating the components for the included page (the first argument of createComponents). On the other hand, all events, including onCreate, are processed later. Thus, if you want to access arg in the onCreate's listener, use the getArg method of the org.zkoss.zk.ui.event.CreateEvent class.
|
| each | java.lang.Object | The current item of the collection being iterated, when ZK evaluates an iterative element. An iterative element is an element with the forEach attribute. |
| forEachStatus | org.zkoss.zk.ui.util.ForEachStatus | The status of an iteration. ZK exposes the information relative to the iteration taking place when evaluating the iterative element. |
| event | org.zkoss.zk.ui.event.Event or derived | The current event. Available for the event listener only. |
