878 \class QTextCursor-
879 \reentrant-
880 \inmodule QtGui-
881-
882 \brief The QTextCursor class offers an API to access and modify QTextDocuments.-
883-
884 \ingroup richtext-processing-
885 \ingroup shared-
886-
887 Text cursors are objects that are used to access and modify the-
888 contents and underlying structure of text documents via a-
889 programming interface that mimics the behavior of a cursor in a-
890 text editor. QTextCursor contains information about both the-
891 cursor's position within a QTextDocument and any selection that it-
892 has made.-
893-
894 QTextCursor is modeled on the way a text cursor behaves in a text-
895 editor, providing a programmatic means of performing standard-
896 actions through the user interface. A document can be thought of-
897 as a single string of characters. The cursor's current position()-
898 then is always either \e between two consecutive characters in the-
899 string, or else \e before the very first character or \e after the-
900 very last character in the string. Documents can also contain-
901 tables, lists, images, and other objects in addition to text but,-
902 from the developer's point of view, the document can be treated as-
903 one long string. Some portions of that string can be considered-
904 to lie within particular blocks (e.g. paragraphs), or within a-
905 table's cell, or a list's item, or other structural elements. When-
906 we refer to "current character" we mean the character immediately-
907 \e before the cursor position() in the document. Similarly, the-
908 "current block" is the block that contains the cursor position().-
909-
910 A QTextCursor also has an anchor() position. The text that is-
911 between the anchor() and the position() is the selection. If-
912 anchor() == position() there is no selection.-
913-
914 The cursor position can be changed programmatically using-
915 setPosition() and movePosition(); the latter can also be used to-
916 select text. For selections see selectionStart(), selectionEnd(),-
917 hasSelection(), clearSelection(), and removeSelectedText().-
918-
919 If the position() is at the start of a block, atBlockStart()-
920 returns \c true; and if it is at the end of a block, atBlockEnd() returns-
921 true. The format of the current character is returned by-
922 charFormat(), and the format of the current block is returned by-
923 blockFormat().-
924-
925 Formatting can be applied to the current text document using the-
926 setCharFormat(), mergeCharFormat(), setBlockFormat() and-
927 mergeBlockFormat() functions. The 'set' functions will replace the-
928 cursor's current character or block format, while the 'merge'-
929 functions add the given format properties to the cursor's current-
930 format. If the cursor has a selection, the given format is applied-
931 to the current selection. Note that when only a part of a block is-
932 selected, the block format is applied to the entire block. The text-
933 at the current character position can be turned into a list using-
934 createList().-
935-
936 Deletions can be achieved using deleteChar(),-
937 deletePreviousChar(), and removeSelectedText().-
938-
939 Text strings can be inserted into the document with the insertText()-
940 function, blocks (representing new paragraphs) can be inserted with-
941 insertBlock().-
942-
943 Existing fragments of text can be inserted with insertFragment() but,-
944 if you want to insert pieces of text in various formats, it is usually-
945 still easier to use insertText() and supply a character format.-
946-
947 Various types of higher-level structure can also be inserted into the-
948 document with the cursor:-
949-
950 \list-
951 \li Lists are ordered sequences of block elements that are decorated with-
952 bullet points or symbols. These are inserted in a specified format-
953 with insertList().-
954 \li Tables are inserted with the insertTable() function, and can be-
955 given an optional format. These contain an array of cells that can-
956 be traversed using the cursor.-
957 \li Inline images are inserted with insertImage(). The image to be-
958 used can be specified in an image format, or by name.-
959 \li Frames are inserted by calling insertFrame() with a specified format.-
960 \endlist-
961-
962 Actions can be grouped (i.e. treated as a single action for-
963 undo/redo) using beginEditBlock() and endEditBlock().-
964-
965 Cursor movements are limited to valid cursor positions. In Latin-
966 writing this is between any two consecutive characters in the-
967 text, before the first character, or after the last character. In-
968 some other writing systems cursor movements are limited to-
969 "clusters" (e.g. a syllable in Devanagari, or a base letter plus-
970 diacritics). Functions such as movePosition() and deleteChar()-
971 limit cursor movement to these valid positions.-
