This is the central component in WPTools, the editor. It hosts the 'RTF-Engine' which is defined in class TWPRTFEnginePaint and available through the property Memo.
The property RTFText is used to store text in any supported format. It is not a reference to the engine, just more or less a container.
Most functionality of the RTFEngine is published by the editor through properties and methods, but especially for the dynamic creation of text it might be useful to use the reference to the active text or the cursor class TextCursor.
The TWPRTFDataCollection which is used by the editor can be referenced by Memo.RTFData. The page size is stored in Header. Different layout modes can be selected in property LayoutMode.

To change the load and save format the properties TextSaveFormat and TextLoadFormat can be modified. But the methods to load and save also can receive an optional parameter specifying the format. Possible format strings are 'RTF', 'ANSI', 'HTML' and 'WPTOOLS'.
The class TWPRichText also has the property CurrAttr to modify the current text attributes. Automatically the current writing attributes or the attributes of the selected text are change. This is useful if you do not want to use the provided GUI controls (TWPToolBar or the standard actions) and want to synchronize your tool buttons. At a lower level, also in TWPCustomRTFedit, the interfaces WritingAttr and SelectedTextAttr are provided. In contrast to CurrAttr this interfaces use Set and Get methods to work with attributes to make it possible to check weather a property is defined. CurrAttr uses standard properties, they are easier to use but less powerful.
