Winter Cardinal UI - v0.457.0 / DDialogSelectListItemUpdater

Class: DDialogSelectListItemUpdater<VALUE>

The primary purpose of this class is to minimize the number of rendered items (e.g., DListItem) as low as possible and to update their positions and states. For this sake, the updater calculates the required number of items whenever their container size changes and creates items if needed.
