[Description] Sets the upper boundary of the values range returned by the slider. This is the value the vertical slider will return in its topmost position and horizontal slider will return in its rightmost position. Negative numbers are accepted. Any attempts to set the slider to the value greater than n_maxValue using the API calls will result in setting it to n_maxValue, no error message will be generated. If n_step is set then it is logical to have n_maxValue so n_maxValue - n_minValue is the multiple of n_step, otherwise the size of the last step will be different from n_step [Accepted Values] number lesser than n_minValue [Key]
