Example 1 with DragSourceDropEvent

use of java.awt.dnd.DragSourceDropEvent in project freeplane by freeplane.

the class MNodeDragListener method dragGestureRecognized.

public void dragGestureRecognized(final DragGestureEvent e) {
    final MainView mainView = (MainView) e.getComponent();

    Rectangle bounds = new Rectangle(0, 0, mainView.getWidth(), mainView.getHeight());
    if (!bounds.contains(e.getDragOrigin()))
        return;
    final int dragActionType = e.getDragAction();

            if (!isLinkDragEvent(e))

    final Transferable t = ClipboardController.getController().copy(Controller.getCurrentController().getSelection());
    ((MindMapNodesSelection) t).setDropAction(dragActionName);
    try {
