static KeyStroke |
convertAcceleratorToKeyStroke(int accelerator)
Given an SWT accelerator value, provide the corresponding key stroke.
|
static int |
convertEventToModifiedAccelerator(Event event)
Converts the given event into an SWT accelerator value -- considering the
modified character with the shift modifier.
|
static int |
convertEventToUnmodifiedAccelerator(Event event)
Converts the given event into an SWT accelerator value -- considering the
unmodified character with all modifier keys.
|
static int |
convertEventToUnmodifiedAccelerator(KeyEvent event)
Converts the given event into an SWT accelerator value -- considering the
unmodified character with all modifier keys.
|
static int |
convertEventToUnshiftedModifiedAccelerator(Event event)
Converts the given event into an SWT accelerator value -- considering the
modified character without the shift modifier.
|
static int |
convertKeyStrokeToAccelerator(KeyStroke keyStroke)
Given a key stroke, this method provides the equivalent SWT accelerator
value.
|
static IKeyFormatter |
getKeyFormatterForPlatform()
Provides an instance of
IKeyFormatter appropriate for the
current instance. |

accelerator
- The accelerator to convert; should be a valid SWT accelerator
value.null
.public static final int convertEventToModifiedAccelerator(Event event)
Converts the given event into an SWT accelerator value -- considering the modified character with the shift modifier. This is the third accelerator value that should be checked when processing incoming key events.
For example, on a standard US keyboard, "Ctrl+Shift+5" would be viewed as "Ctrl+Shift+%".
event
- The event to be converted; must not be null
.public static final int convertEventToUnmodifiedAccelerator(Event event)
Converts the given event into an SWT accelerator value -- considering the unmodified character with all modifier keys. This is the first accelerator value that should be checked when processing incoming key events. However, all alphabetic characters are considered as their uppercase equivalents.
For example, on a standard US keyboard, "Ctrl+Shift+5" would be viewed as "Ctrl+Shift+5".

- The event to be converted; must not be null
