/**
- @class wxRichTextLine
-
- This object represents a line in a paragraph, and stores
- offsets from the start of the paragraph representing the
- start and end positions of the line.
+ @class wxRichTextField
+
+ This class implements the general concept of a field, an object that represents
+ additional functionality such as a footnote, a bookmark, a page number, a table
+ of contents, and so on. Extra information (such as a bookmark name) can be stored
+ in the object properties.
+
+ Drawing, layout, and property editing is delegated to classes derived
+ from wxRichTextFieldType, such as instances of wxRichTextFieldTypeStandard; this makes
+ the use of fields an efficient method of introducing extra functionality, since
+ most of the information required to draw a field (such as a bitmap) is kept centrally
+ in a single field type definition.
+
+ The FieldType property, accessed by SetFieldType/GetFieldType, is used to retrieve
+ the field type definition. So be careful not to overwrite this property.
+
+ wxRichTextField is derived from wxRichTextParagraphLayoutBox, which means that it
+ can contain its own read-only content, refreshed when the application calls the UpdateField
+ function. Whether a field is treated as a composite or a single graphic is determined
+ by the field type definition. If using wxRichTextFieldTypeStandard, passing the display
+ type wxRICHTEXT_FIELD_STYLE_COMPOSITE to the field type definition causes the field
+ to behave like a composite; the other display styles display a simple graphic.
+ When implementing a composite field, you will still need to derive from wxRichTextFieldTypeStandard
+ or wxRichTextFieldType, if only to implement UpdateField to refresh the field content
+ appropriately. wxRichTextFieldTypeStandard is only one possible implementation, but
+ covers common needs especially for simple, static fields using text or a bitmap.
+
+ Register field types on application initialisation with the static function
+ wxRichTextBuffer::AddFieldType. They will be deleted automatically on
+ application exit.
+
+ An application can write a field to a control with wxRichTextCtrl::WriteField,
+ taking a field type, the properties for the field, and optional attributes.
