Ok, I will just post it again here, because the page I created has
been deleted...

After the 1.0 release I started to download the SDK, the NetBeans
plugins and wanted to begin developing. As or main applications deals
with graph based interfaces, I wanted to test how hard it would be to
implement drag'n'drop (in one window, so no transfer objects or what
so
ever). I remembered from my first try outs with JavaFX that there was
this very handy JavaFX Pad. So I have downloaded it
(http://download.java.net/general/openjfx/demos/javafxpad.jnlp) and
there was already the first Node with dragging and moving around
support. Ok, that was cool! So I took a look into the code and checked
out the lines where the magic happens:

var x = 0
var y = 0


onMouseDragged: operation(e) {
        // updating x and y will move the group
        // since a translation transform is bound to them
        x += e.localDragTranslation.x;
        y += e.localDragTranslation.y;

}

Ok, quite easy. Copied that into NetBeans and the only thing that I
got
were errors. After looking around I have found other similar examples
and I have found the type of e, that is CanvasMouseEvent. Ok, added
that
and nothing. After searching the whole internet  ;)  I have found some
comments, that the API has changed. So the classes in the package
javafx.ui.* have been moved or replaced. The CanvasMouseEvent was one
of
the classes that have been replaced and not available anymore. So how
could I do that now? Again after, some hours of google I have found
this
very up to date official tutorial:
http://javafx.com/samples/DragAndDrop/index.html

public-init var maxX = 200;
public-init var maxY = 200;
var startX = 0.0;
var startY = 0.0;

override var onMousePressed = function(e:MouseEvent):Void {
    startX = e.sceneX-translateX;
    startY = e.sceneY-translateY;
}

override var onMouseDragged = function(e:MouseEvent):Void {
    var tx = e.sceneX-startX;
    if(tx < 0) { tx = 0; }
    if(tx > maxX-image.width) { tx = maxX-image.width; }
    translateX = tx;

    var ty = e.sceneY-startY;
    if(ty < 0) { ty = 0; }
    if(ty > maxY-image.height) { ty = maxY-image.height; }
    translateY = ty;
}


So from the quite elegant methode above I have to change my code to
look like this. The very handy field
localDragTranslation is gone. Why? Did I miss something? I mean, I am
really willing to try JavaFX out and
even use it. But the first experience is anything else than a success.
