The implementation of Layout can then cache the calculated size and position within the parent. - Note that position and size should be calculated separately, because - for example inserting a paragraph may result in the following paragraphs - moving down, but not changing in size. - - Need to determine how objects specify their position. Absolute coordinates, - or relative to last object? May be hard to determine that. So should probably - be in absolute coordinates, in which case we'll need a Move virtual function - that allows quick movement of all elements without layout. - - Let's work through a simple example of layout. Say we're laying out - a document with the buffer as the top box, with a wxRichTextParagraphLayoutBox - inside that that consists of wxRichTextParagraph objects. - - We're in a mode whereby changes of window size change the width of the - page (useful for text editors, as opposed to word processors). The - window width is 600. - - We pass (600, -1) to the top-level Layout (i.e. restrict size in horizontal - direction only). The wxRichTextBuffer box doesn't currently have - well-defined layout behaviour so we simply assume it has one child - that fills its parent (later we can define sizer-like box layout behaviour). - So it passes the same dimensions to the child, which is a wxRichTextParagraphLayoutBox. - This then looks at each child in turn (wxRichTextParagraph) and determines - the size the paragraph will take up, setting the cached size, and - splitting the paragraph into lines. - - When the layout for one paragraph returns, the next paragraph is - fed the position of the previous, so it can position itself. - - Each time Layout is called, the cached list of lines for each paragraph - is recreated, since it can change for example if the parent object width - changes. - - Reporting size - ============== - - Each object can report its size for a given range.
