getSVGElementAt

public static List<org.w3c.dom.svg.SVGElement> getSVGElementAt(VectorCanvas canvas,
                                                               Shape shape,

Return List of Selectable SVGElement. It does not return null instead it return empty List. It search from bottom to top because the bottom is the front on the canvas (SVG z-order).

Parameters:

canvas - the VectorCanvas

shape - selection shape

direct - true for direct selection

Returns:

List of Selectable SVGElement

getSVGElementAt

Return List of Selectable SVGElement. It does not return null instead it return empty List It search from bottom to top because the bottom is the front on the canvas (SVG z-order).

Parameters:

canvas - VectorCanvas

point - selection point

direct - true for direct selection

Returns:

List of Selectable SVGElement

getGraphicsElement

public static List<org.w3c.dom.svg.SVGElement> getGraphicsElement(List<org.w3c.dom.svg.SVGElement> source)

This methods traverse the givent Element list, to find the child which is selectable Graphics Element. If nothings found, it return empty list instead of null

Parameters:

getSVGTextElementAt

public static org.w3c.dom.svg.SVGTextElement getSVGTextElementAt(VectorCanvas canvas,
                                                                 Point2D point)

Return SVGTextElement the most front or the most bottom (SVG z-order).

Parameters:

canvas - VectorCanvas

point - Point2D

Returns:

SVGTextElement or null
