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 + wxRichTextParagraphLayoutBox::AddFieldType.
