Detailed Description

template<typename TBaseClass, typename TDerivedClass, typename ListBoxTraits>
class kanzi::ListBoxConceptImpl< TBaseClass, TDerivedClass, ListBoxTraits >

ListBoxConceptImpl provides the common base implementation for the List Box nodes, such as GridListBox2D, GridListBox3D, and TrajectoryListBox3D.

Use the List Box nodes to create lists of selectable items. For example, use the List Box nodes to create contact lists, playlists in a media player, or car settings lists.

A List Box node provides an invisible hit testable area that listens to input and reacts when the user pans the area to browse the list. When the user browses the list, the List Box moves the items so that new items become visible and old items disappear. How this happens depends on the specific List Box.

To disable a List Box node, set the Node::EnabledProperty to false. A disabled List Box does not respond to input. To visually indicate the disabled state of a List Box node, create a state manager and use the Node::EffectivelyEnabledProperty as its controller property. When Kanzi disables a List Box node, it cancels the ongoing gestures and preserves the position of that List Box node.

A List Box node gets its items from an item generator. By default the List Box uses the DefaultListBoxItemGenerator which simply stores the items that are added to it. To create dynamic content for a List Box, replace the item generator with a custom implementation.

A List Box node wraps its items in container nodes that are created by an item container generator. The default item generator creates invisible nodes that do nothing.
