71 Structure of a document:-
72-
73 DOCUMENT :== FRAME_CONTENTS-
74 FRAME :== START_OF_FRAME FRAME_CONTENTS END_OF_FRAME-
75 FRAME_CONTENTS = LIST_OF_BLOCKS ((FRAME | TABLE) LIST_OF_BLOCKS)*-
76 TABLE :== (START_OF_FRAME TABLE_CELL)+ END_OF_FRAME-
77 TABLE_CELL = FRAME_CONTENTS-
78 LIST_OF_BLOCKS :== (BLOCK END_OF_PARA)* BLOCK-
79 BLOCK :== (FRAGMENT)*-
80 FRAGMENT :== String of characters-
81-
82 END_OF_PARA :== 0x2029 # Paragraph separator in Unicode-
83 START_OF_FRAME :== 0xfdd0-
84 END_OF_FRAME := 0xfdd1-
85-
86 Note also that LIST_OF_BLOCKS can be empty. Nevertheless, there is-
87 at least one valid cursor position there where you could start-
88 typing. The block format is in this case determined by the last-
89 END_OF_PARA/START_OF_FRAME/END_OF_FRAME (see below).-
90-
91 Lists are not in here, as they are treated specially. A list is just-
92 a collection of (not necessarily connected) blocks, that share the-
93 same objectIndex() in the format that refers to the list format and-
94 object.-
95-
96 The above does not clearly note where formats are. Here's-
97 how it looks currently:-
98-
99 FRAGMENT: one charFormat associated-
100-
101 END_OF_PARA: one charFormat, and a blockFormat for the _next_ block.-
102-
103 START_OF_FRAME: one char format, and a blockFormat (for the next-
104 block). The format associated with the objectIndex() of the-
105 charFormat decides whether this is a frame or table and its-
106 properties-
107-
108 END_OF_FRAME: one charFormat and a blockFormat (for the next-
109 block). The object() of the charFormat is the same as for the-
110 corresponding START_OF_BLOCK.-
111-
112-
113 The document is independent of the layout with certain restrictions:-
114-
115 * Cursor movement (esp. up and down) depend on the layout.-
116 * You cannot have more than one layout, as the layout data of QTextObjects-
117 is stored in the text object itself.-
