QString converts the const char * data into Unicode using the fromUtf8 () function. In all of the QString functions that take const char * parameters, the const char * is interpreted as a classic C-style '\0'-terminated string encoded in UTF-8. It is legal for the const char * parameter to be 0.static] QString QString:: fromUcs4 (const uint * unicode, int size = -1). Returns a QString initialized with the first size characters of the Unicode string unicode (ISO-10646-UCS-4 encoded). If size is -1 (default), unicode must be terminated with a 0. This function was introduced in Qt 4.2.
If your variable is of primitive type (int), it is better to use Integer.toString(int) or String.valueOf(int). But if your variable is already an instance of Integer (wrapper class of the primitive type int), it is better to just invoke it's toString() method as shown above.onvert using Integer.toString(int). The Integer class has a static method that returns a String object representing the specified int parameter. Using this is an efficient solution. Syntax. The argument i is converted and returned as a string instance.
