  • Method Details

    • convertAcceleratorToKeyStroke

      public static final KeyStroke convertAcceleratorToKeyStroke(int accelerator)
      Given an SWT accelerator value, provide the corresponding key stroke.
      Parameters:
      accelerator - The accelerator to convert; should be a valid SWT accelerator value.
      Returns:
      The equivalent key stroke; never null.
    • convertEventToModifiedAccelerator

      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+%".

      Parameters:
      event - The event to be converted; must not be null.
      Returns:
      The combination of the state mask and the unmodified character.
    • convertEventToUnmodifiedAccelerator

      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".

      Parameters:
      event - The event to be converted; must not be null.
      Returns:
      The combination of the state mask and the unmodified character.
    • convertEventToUnmodifiedAccelerator

      public static final int convertEventToUnmodifiedAccelerator(KeyEvent 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. 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+%".

      Parameters:
      event - The event to be converted; must not be null.
      Returns:
      The combination of the state mask and the unmodified character.
    • convertEventToUnshiftedModifiedAccelerator

      public static final int convertEventToUnshiftedModifiedAccelerator(Event event)
      Converts the given event into an SWT accelerator value -- considering the modified character without the shift modifier. This is the second accelerator value that should be checked when processing incoming key events. Key strokes with alphabetic natural keys are run through convertEventToUnmodifiedAccelerator.
      Parameters:
      event - The event to be converted; must not be null.
      Returns:
      The combination of the state mask without shift, and the modified character.
    • convertKeyStrokeToAccelerator

      public static final int convertKeyStrokeToAccelerator(KeyStroke keyStroke)
      Given a key stroke, this method provides the equivalent SWT accelerator value. The functional inverse of convertAcceleratorToKeyStroke.
      Parameters:
      keyStroke - The key stroke to convert; must not be null.
      Returns:
      The SWT accelerator value
    • getKeyFormatterForPlatform

      public static IKeyFormatter getKeyFormatterForPlatform()
      Provides an instance of IKeyFormatter appropriate for the current instance.
      Returns:
      an instance of IKeyFormatter appropriate for the current instance; never null.
