    String class generates standard string gadgets with
    all editing facilities (clear, undo, etc.) enabled.
String.mui/MUIA_String_Accept

    NAME
    MUIA_String_Accept -- [ISG], STRPTR

    FUNCTION
    A string containing characters allowed as input
    for the string gadget. Whenever the user hits a
    character not found in MUIA_String_Accept, he
    will hear a beep and gadgets contents won't have
    changed.

    EXAMPLE
    StringObject,
       MUIA_String_Accept, "0123456789-",
       End,

    SEE ALSO
    MUIA_String_Reject
String.mui/MUIA_String_Acknowledge

    NAME
    MUIA_String_Acknowledge -- [..G], STRPTR

    FUNCTION
    This attribute will be set to the contents of the
    string whenever the user hits return in the gadget.
    An application can listen with notification and take
    the appropriate action.

    Using the TAB key or a mouse click to deactivate the
    gadget will not trigger MUIA_String_Acknowledge.

    EXAMPLE
    /* two string gadgets str1 and str2, the second should
    /* become active after a return in the first: */

    DoMethod(str1,MUIM_Notify,
       MUIA_String_Acknowledge, MUIV_EveryTime,
       windowobj, 3, MUIM_Set, MUIA_Window_ActiveObject, str2);

String.mui/MUIA_String_AttachedList

    NAME
    MUIA_String_AttachedList -- [I..], Object *

    FUNCTION
    This special attribute can be set to point to
    a valid MUI object of List or Listview class.
    This enables controlling the lists cursor
    from within the string gadget, all cursor key
    events will be forwarded.

    SEE ALSO
    MUIA_String_Contents, MUIA_List_Active
String.mui/MUIA_String_BufferPos

    NAME
    MUIA_String_BufferPos -- [.SG], LONG

    FUNCTION
    MUIA_String_BufferPos can be used to get and set the
    position of the cursor in the string gadget.
    This attribute is probably not very interesting.

    SEE ALSO
    MUIA_String_Contents, MUIA_String_DisplayPos
String.mui/MUIA_String_Contents

    NAME
    MUIA_String_Contents -- [ISG], STRPTR

    FUNCTION
    Get and set a string gadgets contents. You may not
    modify the returned string.

    MUIA_String_Contents gets updated every time when
    the contents of the string gadget change. When you
    set up a notification on this attribute, you will
    hear about every keystroke.

    EXAMPLE

    /* The given hook will be called after every change */
    /* in the string gadget. It receives a pointer to   */
    /* a pointer to the current contents in register a1 */
    /* (see MUIM_CallHook for details)                  */

    DoMethod(str,MUIM_Notify,
       MUIA_String_Contents, MUIV_EveryTime,
       str, 3, MUIM_CallHook, &hook, MUIV_TriggerValue);

    SEE ALSO
    MUIA_String_Accept, MUIA_String_Reject, MUIA_String_MaxLen
String.mui/MUIA_String_DisplayPos

    NAME
    MUIA_String_DisplayPos -- [.SG], LONG

    FUNCTION
    MUIA_String_DisplayPos can be used to get and set the
    number of the first character of the string to be
    displayed. This attribute is probably not very
    interesting.

String.mui/MUIA_String_Format

    NAME
    MUIA_String_Format -- [I.G], LONG

    SPECIAL INPUTS
    MUIV_String_Format_Left
    MUIV_String_Format_Center
    MUIV_String_Format_Right

    FUNCTION
    Used to adjust the alignment of the input string.

    MUIA_String_BufferPos, MUIA_String_DispPos, MUIA_String_Contents
String.mui/MUIA_String_Integer

    NAME
    MUIA_String_Integer -- [ISG], ULONG

    FUNCTION
    Useful for turning a string gadget into an integer
    gadget. Setting this attribute puts the value
    with "%ld" into the gadget, getting it returns
    a longword containing the string gadgets contents
    as number.

    You should set MUIA_String_Accept to "0123456789"
    or something like that to avoid wrong characters.

    EXAMPLE
    StringObject,
       MUIA_String_Accept , "0123456879",
       MUIA_String_Integer, 42,
       End;
String.mui/MUIA_String_MaxLen

    FUNCTION
    Setup the maximum length for the string gadget.

    Default maximum length is 80.

    NOTE: The maximum length includes the 0-byte at the end
          of the string. To let the user enter e.g. 10 characters,
          you would have to specify a maxlen of 11.
