public class Biglistbox
extends XulElement

A component to handle a huge data sets and provides the same and as many as the functionalities of Listbox including selection, sorting, keystroke navigation, ROD(rendering-on-demand), and so on.

Event:

1. SelectEvent is sent when user changes the selection.
2. ScrollEventExt for onScroll is sent when user changes the scroll position either x or y.
3. ScrollEventExt for onScrollY is sent when user changes the scroll position y.
4. ScrollEventExt for onScrollX is sent when user changes the scroll position x.
5. SortEventExt is sent when user sort the column.
6. CellClickEvent is sent when user click upon the cell field.
7. onAfterRender is sent when the model's data has been rendered.

Custom Attributes

org.zkoss.zkmax.zul.biglistbox.preloadSize

.

Specifies the number of items to preload when receiving the rendering request from the client.

Default getZclass(): z-biglistbox.

Note: This component can only support those browsers which support HTML5/CSS3 selector. Like IE8+, Firefox, Safari, Opera, and Chrome.

Since:

6.0.1
