@Deprecated public final class KeyStroke extends Object implements Comparable
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.
