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