Implementation of links drawn with 2 orthogonal segments.
Library: ilvgrapher
Links of the IlvOneLinkImage class are made of two lines forming a right angle, as shown in the following figure:

Constructor.
Initializes a new instance of the IlvOneLinkImage class. The orientation parameter specifies the direction (horizontal or vertical) the link takes upon leaving the from node.
| display | The display connection that handles the drawing of this object. |
| orientation | The orientation for the link. |
| oriented | A Boolean indicating whether an arrowhead is to be drawn at the end of the link. |
| from | The IlvGraphic object representing the start node of the link. |
| to | The IlvGraphic object representing the end node of the link. |
| palette | The palette used to draw the link. |
|

Returns the points defining the shape of the link.
Returns an array of points defining the shape of the link when it is drawn with the transformer t. The size of the resulting array of points is returned in the nPoints parameter. The array is stored in an IlPoolOf(IlvPoint) and should not be deleted or modified.
This method is internally used by the methods draw, contains, and boundingBox. It is meant to replace various methods defined in subclasses in previous releases of Rogue Wave Views; like the obsolete IlvOneLinkImage::getPoints.
This function is overloaded by subclasses defining a specific shape for links. The default implementation returns an array of two points computed with the IlvLinkImage::computePoints method.
| nPoints | The number of points in the returned array. |
| t | The transformer applied to the link. |
Reimplemented from IlvLinkImage.
Reimplemented in IlvOneSplineLinkImage.
| IlvLinkOrientation IlvOneLinkImage::getOrientation | ( | ) | const |
Returns the orientation of the link.
IlvHorizontalLink or IlvVerticalLink). | void IlvOneLinkImage::setOrientation | ( | IlvLinkOrientation | orient | ) |
Changes the orientation of the link.
Sets the orientation of the link (IlvHorizontalLink or IlvVerticalLink).
| orient | The new orientation. |
