示例1: type

break;
case B_LARGE_ICON:
bounds.Set(0, 0, 31, 31);
break;
default:
error = B_BAD_VALUE;
break;
}
// check parameters and initialization
if (error == B_OK
&& (!icon || icon->InitCheck() != B_OK || icon->Bounds() != bounds))

bool success = false;
// Ask the MIME database for the preferred application for the file type
// and whether this application has a special icon for the type.
char signature[B_MIME_TYPE_LENGTH];
