| <p>Provides support for bindings between commands and keys.</p> |
| |
| <h2>Package Specification</h2> |
| <p> |
| This just a key-specific implementation of the generic bindings and trigger |
| support. This package provides an abstraction layer between the SWT key events |
| and key bindings within JFace. |
| </p> |
| <p> |
| <code>KeySequence</code> is a <code>TriggerSequence</code> that has |
| <code>KeyStroke</code> instances as triggers. A <code>KeyStroke</code> is |
| composed of one or more keys held down at the same time. A key stroke ends |
| when the keys are released. A key stroke can contain zero or more modifiers |
| keys, but it always contains exactly one natural key. A modifier key is one of |
| Ctrl, Shift, Alt, or Command. A natural key is anything else.</p> |
| <p> |
| Natural keys are further subdivided into special keys and character keys. |
| Character keys are keys that have an ASCII representation (e.g., Space, 'A' and |
| Backspace). Special keys are ones that do not (e.g., Arrow Up, F11, and |
| NumLock). |
| </p> |
| <p> |
| <code>SWTKeySupport</code> is a static class that provides the link between SWT |
| and these internal representations. It has methods for converting between SWT |
| key events and the internal representation, and vice versa. It also provides |
| access to the native-style key formatting facilities. |
