Method Detail

isSelected

public boolean isSelected()

Returns whether all directions are currently shown. This value is dynamically retrieved from the LinkGraphRenderer.

Specified by:

isSelected in interface ToggleAction

actionPerformed

public void actionPerformed(ActionEvent e)

Toggles the visibility of the directions of the LinkEdges. The implementation of this method actually inverts the current value of the corresponding boolean property inside the LinkGraphRenderer, so no state is kept here.

actionPerformed in interface ActionListener
