public class SelectionRerouteEdge

extends SelectionEdgeClarifiers

A general class for rerouting edges, achieved by delegating the re-routing logic to the graphmodels; extends functionality in SelectionEdgeClarifiers.

If a gragphmodel does not override canChangeConnectedNode() then rerouting is not possible and argo should behave as if rerouting had never been implemented.

Since:

0.13.2

Constructor Detail

SelectionRerouteEdge

public SelectionRerouteEdge(FigEdgeModelElement feme)

Creates a new instance of SelectionRerouteEdge

Method Detail

mousePressed

public void mousePressed(java.awt.event.MouseEvent me)

set up for re-routing.

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent me)

need to 'arm' the rerouting capability with mouseDragged().

don't arm if the edtior's current mode is a figedge create mode, because once a new edge has been created it is not deselected, therefore on the next create an unwanted reroute is performed.

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent me)

perform re-routing if src/dest nodes have changed.

this method needs to be 'armed' by a previous mouseDragged() to avoid the situation where the user just clicks on the message then clicks on some unrelated Fig, without moving the association...

TODO: improve the fig finding algorithm to find the top most fig in the layer. will be useful for nested states in a statechart.
