Provides support for bindings between commands and keys.
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.
KeySequence is a
TriggerSequence that has
KeyStroke instances as triggers. A
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.
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).
SWTKeySupport 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.
Interface Summary Interface Description IKeyLookupA facilitiy for converting the formal representation for key strokes (i.e., used in persistence) into real key stroke instances.
Class Summary Class Description KeyBindingA keyboard shortcut. KeyLookupFactoryA factory class for
KeySequenceis defined as a list of zero or more
KeyStrokes, with the stipulation that all
KeyStrokeobjects must be complete, save for the last one, whose completeness is optional.
KeySequenceTextA wrapper around the SWT text widget that traps literal key presses and converts them into key sequences for display. KeyStrokeA
KeyStrokeis defined as an optional set of modifier keys followed optionally by a natural key.
SWTKeyLookupA look-up table for the formal grammar for keys, and the integer values they represent. SWTKeySupportA utility class for converting SWT events into key strokes.
