/** * UIString is the core renderable entity for all data that is presented by the UI. UIStrings are divided into one * or more UIStringNodes, where each node corresponds to either normal text or markup data. Markup data is defined * as text that will be replaced by some data retrieved from a data store, referenced by DataStoreName:PropertyName. * Markup can change the current style: <Styles:NormalText>, can enable or disable a style attribute: * <Attributes:B> <Attributes:/B>, or it can indicate that the markup should be replaced by the value of the property * from the data store specified in the markup: <SomeDataStoreName:PropertyName>. * UIStrings dynamically generate UIStringNodes by parsing the input text. For example, passing the following string * to a UIString generates 7 tokens: * "The name specified '<SceneData:EnteredName>' is not available. Press <ButtonImages:IMG_A> to continue or <ButtonImages:IMG_B> to cancel." * The tokens generated correspond to: * (0)="The name specified '" * (1)=" <SceneData:EnteredName>" * (2)="' is not available. Press " * (3)="<ButtonImages:IMG_A>" * (4)=" to continue or " * (5)="<ButtonImages:IMG_B>" * (6)=" to cancel." * * The source text for a UIString must be specified outside of the UIString itself. There is no such thing as a * stand-alone UIString. When used in a label, for example, the property which contains the text which will be used * in the label is specified by the UILabel. This value may contain references to other data sources using markup, but * UIStrings cannot be bound to a data store by themselves. When used in a list, the element cell will be responsible * for giving the UIString its source text. * * @todo UIString is supposed to support persistence, so that designers can override the extents for individual nodes * in the string, so it should not be marked transient * * Copyright 1998-2008 Epic Games, Inc.
