Public methods are denoted by utilizing the same color as the "publicly accessed" class in a given inheritance chain. For example, FListBoxClass is highlighted with red, so any methods colored red in the inheritance chain for FListBoxClass are publicly accessible methods for that class.Orange denotes public methods that have been overridden at some point in the inheritance chain.Grey denotes private methods (DO NOT call these methods directly).FListItemClass extends FSelectableItemClass and is basically just a class created for extension purposes. It doesn't contain any methods itself, but just uses those from FSelectableItemClass.When using FListBox, an instance of DataProviderClass is automatically created. A reference to it stored in "this.dataprovider", and the FListBox instance is assigned to the dataprovider in its "view" array (which stores a list of all views associated with the dataprovider). At any time, you can overwrite this "default" dataprovider by manually creating a dataprovider instance and calling: FListBoxInstance.setDataProvider(myDP); Generally, in FListBox, dataprovider methods are called by FSelectableListClass.FLabelClass is the generic label used for each list item. It gets attached inside of the FListItemSymbol instance.FSelectableItemClass contains all methods for individual list items. Though not shown here, FSelectableItemClass inherits from FUIComponentClass.I haven't included any methods/events for FScrollBarClass because it is another FUIComponent in and of itself, and will have it's own seperate diagram. FScrollBar extends FUIComponentClass Essentially, it is important to know that FScrollBarSymbol is attached to FScrollSelectSymbol, and when scrolling occurs, the scrollbar broadcasts the event to FScrollSelectClass which is handled by the "scrollHandler" method of that class.FSelectableListClass extends FUIComponentClass to implement management of individual list items, as well as integration with DataProviderClass. This class is where you will find most base methods that manipulate list items directly (ie., adding, removing, sorting, getting select indices).FScrollSelectListClass extends FSelectableListClass to implement all aspects of scroll handling in the listboxFListBoxClass extends FScrollSelectListClass to implement restriction of visible row number, as well as ability to select multiple list items.FUIComponentClass is of course the mother of all components. It's the base class which handles generic tasks such as focus management, enabled state, style properties/skin elements, and last, but not least, selection change handling.
