fireEvent

protected void fireEvent(int type,
                         int index0,
                         int index1)

Fires a ListDataEvent for all registered listener (thru addListDataListener(org.zkoss.zul.event.ListDataListener).

Note: you can invoke this method only in an event listener.

addListDataListener

public void addListDataListener(ListDataListener l)

Description copied from interface: ListModel

Adds a listener to the list that's notified each time a change to the data model occurs.

Specified by:

addListDataListener in interface ListModel<E>

removeListDataListener

public void removeListDataListener(ListDataListener l)

Description copied from interface: ListModel

Removes a listener from the list that's notified each time a change to the data model occurs.

Specified by:

removeListDataListener in interface ListModel<E>

getSelection

public java.util.Set<E> getSelection()

Description copied from interface: Selectable

Returns current selection.

Specified by:

getSelection in interface Selectable<E>

Returns:

current selection.

addSelection

public void addSelection(E obj)

Description copied from interface: Selectable

Add the specified object into selection.

Notice that this method is designed to be called by a component (such as Listbox). If it is called by an application, the component's selection status won't be changed.

Specified by:

addSelection in interface Selectable<E>

obj - the object to be as selection.

removeSelection

public void removeSelection(java.lang.Object obj)

Description copied from interface: Selectable

Remove the specified object from selection.

Notice that this method is designed to be called by a component (such as Listbox). If it is called by an application, the component's selection status won't be changed.

Specified by:

removeSelection in interface Selectable<E>

Parameters:

obj - the object to be remove from selection.

clearSelection

public void clearSelection()

Description copied from interface: Selectable

Clear all selection.

Notice that this method is designed to be called by a component (such as Listbox). If it is called by an application, the component's selection status won't be changed.

Specified by:

clearSelection in interface Selectable<E>

removeAllSelection

protected void removeAllSelection(java.util.Collection<?> c)

retainAllSelection

protected void retainAllSelection(java.util.Collection<?> c)
