canImport

public boolean canImport(JComponent component,
                         DataFlavor[] flavors)

Only allows importing data if the enclosing library is not read-only.

createTransferable

protected Transferable createTransferable(JComponent c)

Overrides the parent method to set the dragging flag and replaces the selection group with its children if autoboxing is turned on.

Parameters:

c - The component to perform the opeation in.

exportDone

protected void exportDone(JComponent source,
                          Transferable data,
                          int action)

Overrides the parent method to reset the dragging flag in order to accept external drops.

handleExternalDrop

protected void handleExternalDrop(org.jgraph.JGraph graph,
                                  Object[] cells,
                                  Map nested,
                                  org.jgraph.graph.ConnectionSet cs,

                                  double dx,
                                  double dy)

Overrides the parent method to add a group to the dropped cells if autoboxing is turned on.

Parameters:

graph - The graph to perform the operation in.

cells - The cells to be inserted into the library.

nested - The attributes to be assigned to the cells.

cs - The connections to be established between the cells.

pm - The parent map that describes the parent-child relations.
