Constructor & Destructor Documentation

IlvDoubleSplineLinkImage::IlvDoubleSplineLinkImage	(	IlvDisplay *	display,
		IlBoolean	oriented,
		IlvGraphic *	from,
		IlvGraphic *	to,
		IlvPalette *	palette = 0
	)

Constructor.

The constructor initializes a new instance of the IlvDoubleSplineLinkImage class with an automatic orientation layout.

Parameters

display	The display connection that handles the drawing of this object.
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.

IlvDoubleSplineLinkImage::IlvDoubleSplineLinkImage	(	IlvDisplay *	display,
		IlvLinkOrientation	orientation,
		IlBoolean	oriented,
		IlvGraphic *	from,
		IlvGraphic *	to,
		IlvPalette *	palette = 0
	)

Constructor.

The constructor initializes a new instance of the IlvDoubleSplineLinkImage class with an orientation fixed to orientation.

Parameters

display	The display connection that handles the drawing of this object.
orientation	The fixed 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.
