    • drawHandles

      public void drawHandles(GraphicsRef gr, K2DTransform t, Style s)
      Description copied from class: K2DElement
      This method draws handles around the element. The position of the handles is implementation dependent. These handles are typically used to modify the geometry of the element.
      Specified by:
      drawHandles in class K2DElement
      Parameters:
      gr - the Graphics object to draw on.
      t - the transformation to apply to the element.
      s - the style of the element.

    • getDisplayBounds

      public Rectangle getDisplayBounds(K2DTransform t, Style s)
      Description copied from class: K2DElement
      Determines the bounding box of the displayed element in DC. The bounding box is the smallest possible rectangle in which the displayed element fits entirely.
      Specified by:
      getDisplayBounds in class K2DElement
      Parameters:
      t - the transformation used to calculate the display bounds of the element.
      s - the style used to calculate the display bounds of the element.
      Returns:
      the bounding box of the displayed element

    • getGeometry

      Returns:
      The geometry object associated with the element.

    • setGeometry

      public void setGeometry(Geometry geometry)
      Description copied from class: K2DElement
      Sets the geometry object associated with the element.
      Specified by:
      setGeometry in class K2DElement
      Parameters:
      geometry - the geometry

    • touches

      public boolean touches(Point dcCoord, K2DTransform t, Style s)
      Description copied from class: K2DElement
      Determines if the specified device coordinate touches the displayed element. A point touches the element if it overlaps the graphical representation of the element. The style of the element influences the result.
      Specified by:
      touches in class K2DElement
      Parameters:
      dcCoord - the device coordinate
      t - the transformation used to display the element
      s - the style used to display the element
      Returns:
      true if the element contains the point, false otherwise
      See Also:

    • getElements

      public K2DElement[] getElements()

    • setElements

      public void setElements(K2DElement[] elements)

    • getType

      public int getType()
      Description copied from class: K2DElement
      Return the current element type.
      Specified by:
      getType in class K2DElement
      Returns:
      the element type.
      See Also:

    • setSelected

      public void setSelected(boolean selected)
      Description copied from class: K2DElement
      Sets the selection state of the element.
      Overrides:
      setSelected in class K2DElement
      Parameters:
      selected - if true, the element will be selected else it will be unselected

    • getDisplayBoundsWc

      public Rectangle getDisplayBoundsWc(ViewState vs, Style s)
      Determines the bounding box including the style of element in WC (World Coordinates). The bounding box is the smallest possible rectangle in which the displayed element fits entirely. This method offers a basic implementation by transforming the DC getDisplayBounds method result in WC. To optimize performance, each K2DElement should override this method with its own implementation. See existing implementations (K2DPolygon, K2DPoint, K2DPolyline, etc.) for examples.
      Overrides:
      getDisplayBoundsWc in class K2DElement
      Parameters:
      vs - the view state that provides context information to calculate the display bounds of the element.
      s - the style used used to calculate the display bounds of the element.
      Returns:
      the bounding box of the displayed element in WC
