public LabelEditingGraphMousePlugin(int selectionModifiers)

create an instance with overrides

Parameters:

selectionModifiers - for primary selection

Method Detail

mouseClicked

public void mouseClicked(MouseEvent e)

For primary modifiers (default, MouseButton1): pick a single Vertex or Edge that is under the mouse pointer. If no Vertex or edge is under the pointer, unselect all picked Vertices and edges, and set up to draw a rectangle for multiple selection of contained Vertices. For additional selection (default Shift+MouseButton1): Add to the selection, a single Vertex or Edge that is under the mouse pointer. If a previously picked Vertex or Edge is under the pointer, it is un-picked. If no vertex or Edge is under the pointer, set up to draw a multiple selection rectangle (as above) but do not unpick previously picked elements.
