17 Data structures
18 ===============
19
20 Data is represented by a hierarchy of objects, all derived from
21 wxRichTextObject.
22
23 The top of the hierarchy is the buffer, a kind of wxRichTextParagraphLayoutBox.
24 These boxes will allow flexible placement of text boxes on a page, but
25 for now there is a single box representing the document, and this box is
26 a wxRichTextParagraphLayoutBox which contains further wxRichTextParagraph
27 objects, each of which can include text and images.
28
29 Each object maintains a range (start and end position) measured
30 from the start of the main parent box.
31 A paragraph object knows its range, and a text fragment knows its range
32 too. So, a character or image in a page has a position relative to the
33 start of the document, and a character in an embedded text box has
34 a position relative to that text box. For now, we will not be dealing with
35 embedded objects but it's something to bear in mind for later.
36
37 Note that internally, a range (5,5) represents a range of one character.
38 In the public wx[Rich]TextCtrl API, this would be passed to e.g. SetSelection
39 as (5,6). A paragraph with one character might have an internal range of (0, 1)
40 since the end of the paragraph takes up one position.
41
42 Layout
43 ======
44
45 When Layout is called on an object, it is given a size which the object
46 must limit itself to, or one or more flexible directions (vertical
47 or horizontal). So for example a centered paragraph is given the page
48 width to play with (minus any margins), but can extend indefinitely
49 in the vertical direction. The implementation of Layout can then
50 cache the calculated size and position within the parent.

3478 @class wxRichTextField
3479
3480 This class implements the general concept of a field, an object that represents
3481 additional functionality such as a footnote, a bookmark, a page number, a table
3482 of contents, and so on. Extra information (such as a bookmark name) can be stored
3483 in the object properties.
3484
3485 Drawing, layout, and property editing is delegated to classes derived
3486 from wxRichTextFieldType, such as instances of wxRichTextFieldTypeStandard; this makes
3487 the use of fields an efficient method of introducing extra functionality, since
3488 most of the information required to draw a field (such as a bitmap) is kept centrally
3489 in a single field type definition.
3490
3491 The FieldType property, accessed by SetFieldType/GetFieldType, is used to retrieve
3492 the field type definition. So be careful not to overwrite this property.
3493
3494 wxRichTextField is derived from wxRichTextParagraphLayoutBox, which means that it
3495 can contain its own read-only content, refreshed when the application calls the UpdateField
3496 function. Whether a field is treated as a composite or a single graphic is determined
3497 by the field type definition. If using wxRichTextFieldTypeStandard, passing the display
3498 type wxRICHTEXT_FIELD_STYLE_COMPOSITE to the field type definition causes the field
3499 to behave like a composite; the other display styles display a simple graphic.
3500 When implementing a composite field, you will still need to derive from wxRichTextFieldTypeStandard
3501 or wxRichTextFieldType, if only to implement UpdateField to refresh the field content
3502 appropriately. wxRichTextFieldTypeStandard is only one possible implementation, but
3503 covers common needs especially for simple, static fields using text or a bitmap.
3504
3505 Register field types on application initialisation with the static function
3506 wxRichTextParagraphLayoutBox::AddFieldType. They will be deleted automatically
3507 on application exit.
3508
3509 An application can write a field to a control with wxRichTextCtrl::WriteField,
3510 taking a field type, the properties for the field, and optional attributes.
