65 Structure of a document:-
66-
67 DOCUMENT :== FRAME_CONTENTS-
68 FRAME :== START_OF_FRAME FRAME_CONTENTS END_OF_FRAME-
69 FRAME_CONTENTS = LIST_OF_BLOCKS ((FRAME | TABLE) LIST_OF_BLOCKS)*-
70 TABLE :== (START_OF_FRAME TABLE_CELL)+ END_OF_FRAME-
71 TABLE_CELL = FRAME_CONTENTS-
72 LIST_OF_BLOCKS :== (BLOCK END_OF_PARA)* BLOCK-
73 BLOCK :== (FRAGMENT)*-
74 FRAGMENT :== String of characters-
75-
76 END_OF_PARA :== 0x2029 # Paragraph separator in Unicode-
77 START_OF_FRAME :== 0xfdd0-
78 END_OF_FRAME := 0xfdd1-
79-
80 Note also that LIST_OF_BLOCKS can be empty. Nevertheless, there is-
81 at least one valid cursor position there where you could start-
82 typing. The block format is in this case determined by the last-
83 END_OF_PARA/START_OF_FRAME/END_OF_FRAME (see below).-
84-
85 Lists are not in here, as they are treated specially. A list is just-
86 a collection of (not necessarily connected) blocks, that share the-
87 same objectIndex() in the format that refers to the list format and-
88 object.-
89-
90 The above does not clearly note where formats are. Here's-
91 how it looks currently:-
92-
93 FRAGMENT: one charFormat associated-
94-
95 END_OF_PARA: one charFormat, and a blockFormat for the _next_ block.-
96-
97 START_OF_FRAME: one char format, and a blockFormat (for the next-
98 block). The format associated with the objectIndex() of the-
99 charFormat decides whether this is a frame or table and its-
100 properties-
101-
102 END_OF_FRAME: one charFormat and a blockFormat (for the next-
103 block). The object() of the charFormat is the same as for the-
104 corresponding START_OF_BLOCK.-
105-
106-
107 The document is independent of the layout with certain restrictions:-
108-
109 * Cursor movement (esp. up and down) depend on the layout.-
110 * You cannot have more than one layout, as the layout data of QTextObjects-
111 is stored in the text object itself.-
