    A KeyStroke is defined as an optional set of modifier keys followed optionally by a natural key. A KeyStroke is said to be complete if it contains a natural key. A natural key is any Unicode character (e.g., "backspace", etc.), any character belonging to a natural language (e.g., "A", "1", "[", etc.), or any special control character specific to computers (e.g., "F10", "PageUp", etc.).

    All KeyStroke objects have a formal string representation available via the toString() method. There are a number of methods to get instances of KeyStroke objects, including one which can parse this formal string representation.

    All KeyStroke objects, via the format() method, provide a version of their formal string representation translated by platform and locale, suitable for display to a user.

    KeyStroke objects are immutable. Clients are not permitted to extend this class.

        public static final String KEY_DELIMITER
        Deprecated.
        The delimiter between multiple keys in a single key strokes -- expressed in the formal key stroke grammar. This is not to be displayed to the user. It is only intended as an internal representation.

      • getInstance

        public static KeyStroke getInstance​(ModifierKey modifierKey,
                                            NaturalKey naturalKey)
        Deprecated.
        Gets an instance of KeyStroke given a single modifier key and a natural key.
        Parameters:
        modifierKey - a modifier key. Must not be null.
        naturalKey - the natural key. May be null.
        Returns:
        a key stroke. Guaranteed not to be null.
      • getInstance

                                            NaturalKey naturalKey)
        Deprecated.
        Gets an instance of KeyStroke given an array of modifier keys and a natural key.
        Parameters:
        modifierKeys - the array of modifier keys. This array may be empty, but it must not be null. If this array is not empty, it must not contain null elements.
        naturalKey - the natural key. May be null.
        Returns:
        a key stroke. Guaranteed not to be null.
      • getInstance

        public static KeyStroke getInstance​(NaturalKey naturalKey)
        Deprecated.
        Gets an instance of KeyStroke given a natural key.
        Parameters:
        naturalKey - the natural key. May be null.
        Returns:
        a key stroke. This key stroke will have no modifier keys. Guaranteed not to be null.
      • getInstance

        public static KeyStroke getInstance​(SortedSet modifierKeys,
                                            NaturalKey naturalKey)
        Deprecated.
        Gets an instance of KeyStroke given a set of modifier keys and a natural key.
        Parameters:
        modifierKeys - the set of modifier keys. This set may be empty, but it must not be null. If this set is not empty, it must only contain instances of ModifierKey.
        naturalKey - the natural key. May be null.
        Returns:
        a key stroke. Guaranteed not to be null.
      • getInstance

                                     throws ParseException
        Deprecated.
        Gets an instance of KeyStroke by parsing a given a formal string representation.
        Parameters:
        string - the formal string representation to parse.
        Returns:
        a key stroke. Guaranteed not to be null.
        Throws:
        ParseException - if the given formal string representation could not be parsed to a valid key stroke.

        Deprecated.
        Returns the set of modifier keys for this key stroke.
        Returns:
        the set of modifier keys. This set may be empty, but is guaranteed not to be null. If this set is not empty, it is guaranteed to only contain instances of ModifierKey.
