CreateEdgeMode(/*GraphCanvas*/ canvas, /*Boolean*/ routeEdges)

This is an input mode for creating edges. A CanvasDragLine is used to display the potential edge once the input mode is activated (see activate).

Parameters:

canvas - the canvas

routeEdges - route newly created edges (optional, default false)

activate

activate()

activates this instance. If the attribute startNode is not set, the instance deactivates itself immediately. Otherwise the CanvasDragLine becomes visible. It is assumed that the left mouse button is pressed. An edge is created when the user eventually releases the button while the mouse is over a node. For creating self loops, the user has to leave the start node and enter it again before releasing the button.

deactivate

deactivate()

deactivates this instance. The CanvasDragLine becomes invisible.
