872 \class QTextCursor-
873 \reentrant-
874 \inmodule QtGui-
875-
876 \brief The QTextCursor class offers an API to access and modify QTextDocuments.-
877-
878 \ingroup richtext-processing-
879 \ingroup shared-
880-
881 Text cursors are objects that are used to access and modify the-
882 contents and underlying structure of text documents via a-
883 programming interface that mimics the behavior of a cursor in a-
884 text editor. QTextCursor contains information about both the-
885 cursor's position within a QTextDocument and any selection that it-
886 has made.-
887-
888 QTextCursor is modeled on the way a text cursor behaves in a text-
889 editor, providing a programmatic means of performing standard-
890 actions through the user interface. A document can be thought of-
891 as a single string of characters. The cursor's current position()-
892 then is always either \e between two consecutive characters in the-
893 string, or else \e before the very first character or \e after the-
894 very last character in the string. Documents can also contain-
895 tables, lists, images, and other objects in addition to text but,-
896 from the developer's point of view, the document can be treated as-
897 one long string. Some portions of that string can be considered-
898 to lie within particular blocks (e.g. paragraphs), or within a-
899 table's cell, or a list's item, or other structural elements. When-
900 we refer to "current character" we mean the character immediately-
901 \e before the cursor position() in the document. Similarly, the-
902 "current block" is the block that contains the cursor position().-
903-
904 A QTextCursor also has an anchor() position. The text that is-
905 between the anchor() and the position() is the selection. If-
906 anchor() == position() there is no selection.-
907-
908 The cursor position can be changed programmatically using-
909 setPosition() and movePosition(); the latter can also be used to-
910 select text. For selections see selectionStart(), selectionEnd(),-
911 hasSelection(), clearSelection(), and removeSelectedText().-
912-
913 If the position() is at the start of a block, atBlockStart()-
914 returns \c true; and if it is at the end of a block, atBlockEnd() returns-
915 true. The format of the current character is returned by-
916 charFormat(), and the format of the current block is returned by-
917 blockFormat().-
918-
919 Formatting can be applied to the current text document using the-
920 setCharFormat(), mergeCharFormat(), setBlockFormat() and-
921 mergeBlockFormat() functions. The 'set' functions will replace the-
922 cursor's current character or block format, while the 'merge'-
923 functions add the given format properties to the cursor's current-
924 format. If the cursor has a selection, the given format is applied-
925 to the current selection. Note that when only a part of a block is-
926 selected, the block format is applied to the entire block. The text-
927 at the current character position can be turned into a list using-
928 createList().-
929-
930 Deletions can be achieved using deleteChar(),-
931 deletePreviousChar(), and removeSelectedText().-
932-
933 Text strings can be inserted into the document with the insertText()-
934 function, blocks (representing new paragraphs) can be inserted with-
935 insertBlock().-
936-
937 Existing fragments of text can be inserted with insertFragment() but,-
938 if you want to insert pieces of text in various formats, it is usually-
939 still easier to use insertText() and supply a character format.-
940-
941 Various types of higher-level structure can also be inserted into the-
942 document with the cursor:-
943-
944 \list-
945 \li Lists are ordered sequences of block elements that are decorated with-
946 bullet points or symbols. These are inserted in a specified format-
947 with insertList().-
948 \li Tables are inserted with the insertTable() function, and can be-
949 given an optional format. These contain an array of cells that can-
950 be traversed using the cursor.-
951 \li Inline images are inserted with insertImage(). The image to be-
952 used can be specified in an image format, or by name.-
953 \li Frames are inserted by calling insertFrame() with a specified format.-
954 \endlist-
955-
956 Actions can be grouped (i.e. treated as a single action for-
957 undo/redo) using beginEditBlock() and endEditBlock().-
958-
959 Cursor movements are limited to valid cursor positions. In Latin-
960 writing this is between any two consecutive characters in the-
961 text, before the first character, or after the last character. In-
962 some other writing systems cursor movements are limited to-
963 "clusters" (e.g. a syllable in Devanagari, or a base letter plus-
964 diacritics). Functions such as movePosition() and deleteChar()-
965 limit cursor movement to these valid positions.-
