    • onPropertyChanged

      protected <T> void onPropertyChanged(Key<T> key, @Nullable T oldValue, @Nullable T newValue, boolean wasAdded, boolean wasRemoved)
      Description copied from class: AbstractFigure
      Overrides of this method must call super!
      Overrides:
      onPropertyChanged in class AbstractFigure
      Type Parameters:
      T - the value type of the property
      Parameters:
      key - the changed key
      oldValue - the old value
      newValue - the new value
      wasAdded - whether the value was added (hence oldValue does not matter)
      wasRemoved - whether the value was removed (hence newValue does not matter)

      Parameters:
      drawing - the drawing

    • getCssLayoutBounds

      public CssRectangle2D getCssLayoutBounds()
      Specified by:
      getCssLayoutBounds in interface Figure

    • getLayoutSubjects

      public ReadOnlySet<Figure> getLayoutSubjects()
      Returns all figures which are connected by this figure - they provide to the layout of this figure.
      Specified by:
      getLayoutSubjects in interface Figure
      Returns:
      an unmodifiable set of connected figures

    • isConnected

      public boolean isConnected()

    • isLayoutable

      public boolean isLayoutable()
      Description copied from interface: Figure
      Whether the layout method of this figure does anything.

      The default implementation returns false.

      Specified by:
      isLayoutable in interface Figure
      Returns:
      true if the layout method is not empty.

    • removeAllLayoutSubjects

      public void removeAllLayoutSubjects()
      Description copied from class: AbstractFigure
      This implementation is empty.
      Specified by:
      removeAllLayoutSubjects in interface Figure

      Parameters:
      subject - the connected figure

    • reshapeInLocal

      public void reshapeInLocal(javafx.scene.transform.Transform transform)
      Description copied from interface: Figure
      Attempts to change the local bounds of the figure.

      The figure may choose to only partially change its local bounds.

      Specified by:
      reshapeInLocal in interface Figure
      Specified by:
      reshapeInLocal in interface NonTransformableFigure
      Parameters:
      transform - the desired transformation in local coordinates

    • reshapeInLocal

      public void reshapeInLocal(CssSize x, CssSize y, CssSize width, CssSize height)
      Description copied from interface: Figure
      Attempts to change the local bounds of the figure.

      See {#link #reshapeInLocal(Transform)} for a description of this method.

      This method takes parameters as CssSizes. This can be used to avoid rounding errors when the figure is reshaped in non-pixel units.

      This method can forward a call to Figure.reshapeInLocal(Transform) using the following code: 

      
 void reshapeInLocal(CssSize x, CssSize y, CssSize width, CssSize height) {
   Transform tx = Transforms.createReshapeTransform(getCssBoundsInLocal(), x, y, width, height);
   reshapeInLocal(tx);
 }
      Specified by:
      reshapeInLocal in interface Figure
      Parameters:
      x - desired x-position in parent coordinates
      y - desired y-position in parent coordinates
      width - desired width in parent coordinates, may be negative
      height - desired height in parent coordinates, may be negative

    • updateConnectedProperty

      protected void updateConnectedProperty()

    • connectedProperty
