 { get; set; }

C++

public:
static property bool CursorVisible {
    bool get ();
    void set (bool value);
}

J#

/** @property */
public static boolean get_CursorVisible ()

/** @property */
public static void set_CursorVisible
 (boolean value)

JScript

public static function get
 CursorVisible () : boolean

public static function set
 CursorVisible (value : boolean)

プロパティ値
カーソルを表示する場合は true。それ以外の場合は false。

例外

例外の種類	条件
