Method Detail

acceptBend

protected boolean acceptBend(Node start,
                             Node hitNode,
                             double x,
                             double y)

Apart from the default behaviour, also accept a bend if its coordinate lies within the inner region of a group node. A coordinate that lies on the border of the group node will not be accepted.

Overrides:

acceptBend in class CreateEdgeMode

Parameters:

start - the node from where edge creation started

hitNode - the node that was hit at the given location

x - the x-coordinate of the current location

y - the y-coordinate of the current location
