    • getRealm

      @Deprecated public static Realm getRealm(Display display)
      Deprecated.
      please use DisplayRealm.getRealm(Display) instead.
      Returns the realm representing the UI thread for the given display.
      Parameters:
      display - the display to get realm for
      Returns:
      the realm representing the UI thread for the given display

    • observeDelayedValue

      @Deprecated public static ISWTObservableValue observeDelayedValue(int delay, ISWTObservableValue observable)
      Deprecated.
      use WidgetProperties instead
      Returns an observable which delays notification of value change events from observable until delay milliseconds have elapsed since the last change event, or until a FocusOut event is received from the underlying widget (whichever happens first). This observable helps to boost performance in situations where an observable has computationally expensive listeners (e.g. changing filters in a viewer) or many dependencies (master fields with multiple detail fields). A common use of this observable is to delay validation of user input until the user stops typing in a UI field.

      To notify about pending changes, the returned observable fires a stale event when the wrapped observable value fires a change event, and remains stale until the delay has elapsed and the value change is fired. A call to getValue() while a value change is pending will fire the value change immediately, short-circuiting the delay.

      Only updates resulting from the observed widget are delayed. Calls directly to IObservableValue.setValue(T) are not, and they cancel pending delayed values.

      Note that this observable will not forward ValueChangingEvent events from a wrapped IVetoableValue.

      Parameters:
      delay - the delay in milliseconds
      observable - the observable being delayed
      Returns:
      an observable which delays notification of value change events from observable until delay milliseconds have elapsed since the last change event.
      Since:
      1.2
