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

NAME
MUIA_String_Accept -- (V4 ) [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
NAME
MUIA_String_Acknowledge -- (V4 ) [..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);

MUIA_String_Contents
NAME
MUIA_String_AdvanceOnCR -- (V11) [ISG], BOOL
FUNCTION
Set this if you want carriages returns in string gadgets
behave like the TAB key, i.e. pressing CR will activate
the next/previous gadget in the cycle chain.
SEE ALSO
Notify.mui/MUIA_CycleChain
NAME
MUIA_String_AttachedList -- (V4 ) [ISG], Object *
FUNCTION
This special attribute can be set to point to
a valid MUI object of 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, list.mui/MUIA_List_Active
NAME
MUIA_String_BufferPos -- (V4 ) [.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
NAME
MUIA_String_Contents -- (V4 ) [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.
NOTE
If you try to set contents to something larger
than MUIA_String_MaxLen (including the 0-byte!),
MUI will silently strip the additional characters.
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
NAME
MUIA_String_DisplayPos -- (V4 ) [.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.
SEE ALSO
MUIA_String_Contents, MUIA_String_BufferPos
NAME
MUIA_String_EditHook -- (V7 ) [ISG], struct Hook *
FUNCTION
When specified, MUI calls this hook as if it was a real
string edit hook in a real string gadget. It receives
a pointer to itself in A0, a pointer to a SGWork structure
in A2 and a pointer to the message in A1.
The hook will be called before MUI's private edit hook,
the result is unused.
NAME
MUIA_String_Format -- (V4 ) [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.
SEE ALSO
MUIA_String_BufferPos, MUIA_String_DisplayPos, MUIA_String_Contents
NAME
MUIA_String_Integer -- (V4 ) [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;
NAME
MUIA_String_LonelyEditHook -- (V11) [ISG], BOOL
FUNCTION
If your string object has an edit hook, you can set
this to TRUE to skip MUI's private edit hook completely.
Otherwise, your hook will be executed and the MUIs.
NAME
MUIA_String_MaxLen -- (V4 ) [I.G], LONG
FUNCTION
Setup the maximum length for the string gadget.
This attribute is only valid at object creation time.
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.
SEE ALSO
MUIA_String_Contents
NAME
MUIA_String_Reject -- (V4 ) [ISG], STRPTR
FUNCTION
A string containing characters that should not be
accepted as input for the string gadget. Whenever
the user hits such a char, he will hear a beep
and gadgets contents won't have changed.
SEE ALSO
MUIA_String_Accept
NAME
MUIA_String_Secret -- (V4 ) [I.G], BOOL
FUNCTION
This attribute causes the string gadget to display only
dots instead of the real contents. Useful for password
requesters.
