inline

Snaps towards given direction from given position.

Returns snapping target and index of the object that scrolling snapped to, unless they're given as KZ_NULL. The changeTarget should be KZ_TRUE if the list box target is changed to the snapped item.

If snapping happened towards no object, index will be -1.

void kanzi::ListBoxTrajectoryPresenter< TFinalClass, TLayout, TItemClass, TScrollView >::iterateLeft ( KzuVirtualItemIterator * it )

inlineprotected

Iterates left in virtual item list.

This operation might extend presenters range of visible items if the size of an item where iterator will be pointing to could not be determined otherwise.

Parameters

it	Iterator to iterate.

template<typename TFinalClass , typename TLayout , typename TItemClass , typename TScrollView >

void kanzi::ListBoxTrajectoryPresenter< TFinalClass, TLayout, TItemClass, TScrollView >::iterateRight ( KzuVirtualItemIterator * it )

Iterates right in virtual item list.

This operation might extend presenters range of visible items if the size of an item where iterator will be pointing to could not be determined otherwise.

Parameters

it	Iterator to iterate.

Gets object's width from its size for virtual item list.

template<typename TFinalClass , typename TLayout , typename TItemClass , typename TScrollView >

void kanzi::ListBoxTrajectoryPresenter< TFinalClass, TLayout, TItemClass, TScrollView >::extendVisibleItemRangeToItem ( unsigned int index )

inlineprotected

Extends visible range of presenter to it includes specified item.

If item is already inside the visible range, then the range will remain unchanged.

Parameters

index Index of the item which should be included into the range.

template<typename TFinalClass , typename TLayout , typename TItemClass , typename TScrollView >

Vector3 kanzi::ListBoxTrajectoryPresenter< TFinalClass, TLayout, TItemClass, TScrollView >::getItemSize ( unsigned int itemIndex )

inlineprotected

Returns size of an item specified by its index.

If the item is outside of presenters range of visible items and its size could not be determined by list box, the visible range will be extended so list box can acquire the item and determine its size.

Parameters

itemIndex Index of an item whose size should be returned.

Returns: size of an item.

template<typename TFinalClass , typename TLayout , typename TItemClass , typename TScrollView >

unsigned int kanzi::ListBoxTrajectoryPresenter< TFinalClass, TLayout, TItemClass, TScrollView >::getItemCount ( )

inlineprotected

Gets number of items in presenters list box.

Returns: item count.
