Control Click to Change Tab Order

Question

I know there are new ways to move the field names around to change form fields, but I miss the ability to change tab order by control clicking on the field. I like the new ones, but would like to have the old way also.

Answer 1

You can get the coordinates of the mouse "drop" relative to the scene in the onDragDropped handler with
event.getSceneX() and event.getSceneY().
You can get the location of the top left of a node relative to the scene with
private Point2D getSceneLocation(Node node) {
     if (node.getScene() == null) {
          return new Point2D(0,0);
     double x = 0 ;
     double y = 0 ;
     for (Node n = node ; n != null; n=n.getParent()) {
          Bounds boundsInParent = n.getBoundsInParent();
          x += boundsInParent.getMinX();
          y += boundsInParent.getMinY();
     return new Point2D(x, y);
(and you can get the other corners of the node simply by adding the width and/or height from node.getBoundsInLocal() to the result of that if you need.)
So if you ensure every tab has a graphic, you can iterate through the tabs and do something like
int dropIndex = 0 ;
for (Tab tab : tabPane.getTabs()) {
     Point2D tabLocationInScene = getSceneLocation(tab.getGraphic());
     if (tabLocationInScene.getX() > event.getSceneX()) {
          break ;
     } else {
          dropIndex++ ;
tabPane.getTabs().add(dropIndex, tabToBeAdded);
Ensuring every tab has a graphic probably just means setting the text to an empty string and setting the graphic to a Label containing the text; or I guess you could just use a zero width and height Rectangle, or some such.
