this is an english speaking board, so for the best chance to get an answer try to ask in english

whoops, that's definately embarrassing, I changed it ;-)

Hm, I assume it uses Reflections...

        mSliders[si] = mControlP5.addSlider("mDotSize", 0, 10, left, top + posY + 0, len, 15);
        mSliders[si].setLabel("dotSize");
        mSliders[si++].plugTo("mDotSize");

The method plugTo isn't found, I've included the controlP5.jar library in my project (in a Maven repository), do I have to include anything else?

Maybe it would be great to get away from reflections in a future release since they are of orders slower than regular static or instance methods, but I assume it would break the API completely :(

plugTo has only been included since 0.5.4, the parameter required for the plugTo method is of type Object, in your case i believe it would be a reference to your Swing GUI instead of String "mDotSize" ( plugTo example).

Seems I've had another version.

Hm, currently it seems I'm too stupid, maybe it should be a reference to the PApplet?

1.     /**
        * Constructor.
        *
        * @param paramParentApplet
        *            Parent processing applet.
        * @param paramController
        *            The controller.
        */
       private SunburstGUI(final PApplet paramParentApplet,
           final SunburstController<? extends AbsModel, ? extends AbsView> paramController) {
           mParent = paramParentApplet;
           mController = paramController;
       }
   
       /**
        * Factory method (Singleton).
        *
        * @param paramParentApplet
        *            Parent processing applet.
        * @param paramController
        *            The controller.
        * @return a GUI singleton.
        */
       static SunburstGUI createGUI(final PApplet paramParentApplet,
           final SunburstController<? extends AbsModel, ? extends AbsView> paramController) {
           if (mGUI == null) {
               mGUI = new SunburstGUI(paramParentApplet, paramController);
           }
           return mGUI;
       }

But it seems

        mSliders[si] = mControlP5.addSlider("mDotSize", 0, 10, left, top + posY + 0, len, 15);
        mSliders[si].setLabel("dotSize");
        mSliders[si++].plugTo(mParent);

doesn't work. Well, I'm a bit confused ;-) My embedded processing application invokes in setup() the factory singleton method createGUI(...) and then calls setupGUI() where these sliders are setup.

if  mDotSize belongs to your SunburstGUI, then your slider should plugTo mGUI instead of mParent.

We are getting closer I think ;-)

I use plugTo(this);

and get the following warning:

Nov 9, 2010 4:01:16 PM controlP5.ControllerPlug set
WARNING:  plug() failed.java.lang.NoSuchMethodException: com.treetank.gui.view.sunburst.SunburstGUI.controlEvent(controlP5.ControlEvent)

Well, the method exists:

    /**
     * Called on every change of the GUI.
     *
     * @param paramControlEvent
     *            The {@link ControlEvent}, which is happening.
     */
    @SuppressWarnings("unchecked")
    void controlEvent(final ControlEvent paramControlEvent) {
       ...
    }

Maybe it has to be public? Will check it.

Well, that's it ;-)

Now what's remaining is, that the initial values aren't corresponding to the variable values I globally set (transient float mDotSize = 3f;)

It seems with the appropriate parameter it's working:

mSliders[si] = mControlP5.addSlider("mDotSize", 0, 10, mDotSize, left, top + posY + 0, len, 15);

In Processing it also works without the mDotSize parameter (not the String value, the fourth parameter). Nontheless, now I'm quiet happy, looks better than Swing GUI elements ;-) Well, now I have to debug my Sunburst application, haha, but that's another story ;-)

Thanks for responding so quickly and helping out.

regards,
Johannes

ok, maybe this one helps

Thanks Andreas, but it seems it's also working with the approach described in my posting above. I just wondered why processing figures out that it has to use the dotSize default value even though it's not specified.

In processing this works:
sliders[si++] = controlP5.addSlider("dotSize",0,10,left,top+posY+0,len,15);

In Java I have to provide dotSize as the fourth parameter for the default value. I'm just wondering what's the difference, maybe that my dotSize is package private instead of public, but I don't think this makes any difference.

Well, everything's fine now ;-)
