22 The QStrList class provides a doubly-linked list of char*.
23 If you want a string list of QStrings use QStringList.
25 This class is a QPtrList<char> instance (a list of char*).
27 QStrList can make deep or shallow copies of the strings that are
29 inserted.
30 A deep copy means that memory is allocated for the string and then the
32 string data is copied into that memory. A shallow copy is just a copy
33 of the pointer value and not of the string data itself.
34 The disadvantage of shallow copies is that because a pointer can be
36 deleted only once, the program must put all strings in a central place
37 and know when it is safe to delete them (i.e. when the strings are no
38 longer referenced by other parts of the program). This can make the
39 program more complex. The advantage of shallow copies is that they
40 consume far less memory than deep copies. It is also much faster to
41 copy a pointer (typically 4 or 8 bytes) than to copy string data.
42 A QStrList that operates on deep copies will, by default, turn on auto-
44 deletion (see setAutoDelete()). Thus, by default QStrList will
45 deallocate any string copies it allocates.
46 The virtual compareItems() function is reimplemented and does a case-
48 sensitive string comparison. The inSort() function will insert strings
49 in sorted order. In general it is fastest to insert the strings as they
50 come and sort() at the end; inSort() is useful when you just have to
51 add a few extra strings to an already sorted list.
52 The QStrListIterator class is an iterator for QStrList.
54 See also Collection Classes, Text Related Classes, and Non-GUI Classes.
56
59 Constructs an empty list of strings. Will make deep copies of all
60 inserted strings if deepCopies is TRUE, or use shallow copies if
61 deepCopies is FALSE.
62
64 Constructs a copy of list.
65 If list has deep copies, this list will also get deep copies. Only the
67 pointers are copied (shallow copy) if the other list does not use deep
68 copies.
69
71 Destroys the list. All strings are removed.
72
74 Assigns list to this list and returns a reference to this list.
75 If list has deep copies, this list will also get deep copies. Only the
77 pointers are copied (shallow copy) if the other list does not use deep
78 copies.
