FUNCTION
To provide gadget simular to the gadtools.library it's string and
integer gadget kinds. Objects from this class sends out the following
attribute pairs in their notification events:
GA_ID - Gadget object ID.
STRINGA_TextVal - Gadget object string contents (string objects).
STRINGA_LongVal - Gadget object integer contents (integer objects).
stringclass/Methods stringclass/Methods
NEW METHODS
SM_FORMAT_STRING -- This method may be used to set a formatted string
in a string object. The formatted string may also contain any
locale.library compatible formatting codes. This method uses
the following custom message structure:
struct smFormatString {
ULONG MethodID; /* SM_FORMAT_STRING */
struct GadgetInfo *smfs_GInfo; /* GadgetInfo */
UBYTE *smfs_FStr; /* Format string */
ULONG smfs_Arg1; /* Format arg */
/* ULONG smfs_Arg2; */
/* ... */
};
smfs_GInfo -- This must point to a valid GadgetInfo structure
if the change must also be shown visually on screen.
The BGUI_DoGadgetMethod() call will automatically
construct this for you.
smfs_FStr -- This must point to a 0-terminated string which
contains the formatting codes. Also all locale.library
it's FormatString() formatting codes are supported
when the locale.library is available.
amfs_Arg1 -- This must be the first argument that the string
expects. This can be followed by as much arguments as
are expected by the specified formatting string.
NOTE: This method will only work on string objects. Not on
integer objects.
Returns TRUE uppon success and FALSE uppon failure.
CHANGED METHODS
None.

NOTE
All system strgclass attributes are also supported by this class.
Please refere to the documentation on the strgclass for more
information on these attributes.
NAME
STRINGA_MinCharsVisible -- ( ULONG ) ** V39 **
FUNCTION
To make it possible to determine the minimum amount of characters
which should always stay visible.
Default is 2. Applicability is (I).
NAME
STRINGA_IntegerMin, STRINGA_IntegerMax -- ( ULONG ) ** V39 **
FUNCTION
To set the minimum and maximum value which the integer object can
hold. When a STRINGA_LongVal is set which is out of this range the
value is adjusted to be inside these boundaries. Also when the user
enters a value outside these boundaries the screen will flash and the
entered value is adjusted and not accepted.
Defaults are 0xEFFFFFFF minimum and 0x0FFFFFFF maximum. Applicability
is (ISU).
