                   float hs)

getCp2

public com.google.gwt.dom.client.Element getCp2()

processMouseMove

public abstract void processMouseMove(org.vectomatic.dom.svg.OMSVGPoint delta,
                                      com.google.gwt.dom.client.Element target,
                                      float hs,
                                      boolean isCtrlKeyDown)

Updates the vertex, control points and tangents defining the segment

Parameters:

delta - The translation to apply

target - The vertex, control point or tangeant to update. null means the segment endpoint vertex

hs - The control point size

isCtrlKeyDown - True if the control key is pressed (spline will interpret this to preserve the angle between tangents when a tangent control point is dragged)
