UIListController

The UIListController component manages a list of views based on a list of components.

class UIListController

extends UIRenderableController<UIContainer>

Renderable wrapper that populates an encapsulated container with components, constructed using given view adapter (e.g. preset constructor for UIListCellAdapter components); each instance of the view adapter corresponds to exactly one value from a list.

Constructor

(content?: UIContainer): UIListController

.onFocusIn() protected

(e: ComponentEvent<Component>): boolean

.onArrowDownKeyPress() protected

(): boolean

Handle ArrowDownKeyPress events, focusing the next list item.

.enableArrowKeyFocus

boolean

Set to true to enable selection (focus movement) using up/down arrow keys.

.items

ManagedList<ManagedObject>

List of objects, each object is used to construct one content component.

.firstIndex

number

Index of first item to be shown in the list (for e.g. pagination, or sliding window positioning), defaults to 0.

.maxItems

number

Maximum number of items to be shown in the list (for e.g. pagination, or sliding window positioning), defaults to undefined to show all items.

.lastFocusedIndex

number

Last focused index, if any.

.getIndexOfComponent()

(component?: Component): number

Returns the list index of given component, or of the component that it is contained in; or returns -1 if given component is not found in the list.

.restoreFocus()
