P2D/P3D and Opengl render not working

[joaodafonseca]

The library doesn't work in any of the above renders, any way to make this working?

Just ran into this bug which left me pretty confused. Happy to have found this message and can confirm that in Processing 3.1.1 it also failed to allow drag + drop when using P3D render.

[clankill3r]

+1 for processing 3.1.2

[markusand]

The same for 3.2.1.
I don't know what are the changes in this library from the original one, but I was hoping this would work correctly in P2D at least. I think it's a really needed feature.

+1

Same for 3.3.6 and 3.3.7

A quasi workaround is to create a 2nd window applet for the drag+drop function using default renderer:

// DRAG + DROP
import drop.*;
SDrop drop;
MyDropListener m;

PImage img;
String imgPath = "";

// second window
SecondApplet sa;
boolean saInit = true;

void settings() {
  size(512, 512, P3D);
}

void setup() {
  surface.setResizable(true);

  String[] args = {"blah"};
  sa = new SecondApplet();
  PApplet.runSketch(args, sa);
}

void draw() {
  background(0);
  if (img != null) {
    image(img, 0, 0);
  }
}

// a custom DropListener class.
class MyDropListener extends DropListener {
  int myC = 0;

  MyDropListener() {
    setTargetRect(0, 0, sa.width, sa.height);
  }

  void draw() {
    sa.noStroke();
    sa.fill(0, 255, 0, myC);
    sa.rect(0, 0, sa.width, sa.height);
    sa.stroke(0);
  }
  void dropEnter() {
    myC = 100;
  }
  void dropLeave() {
    myC = 0;
  }

  void dropEvent(DropEvent theEvent) {
    img = null;
    imgPath = theEvent.toString();
    println("imgPath: " + imgPath);
    img = loadImage(imgPath);
  }
}

public class SecondApplet extends PApplet {
  public void settings() {
    size(200, 200);
  }
  public void setup() {
    surface.setTitle("dragImage");
    drop = new SDrop(this);
    m = new MyDropListener();
    drop.addDropListener(m);
  }
  public void draw() {
    if (saInit) {
      surface.setLocation(0, 0);
      saInit= false;
    }
    background(255);
    m.draw();
    frame.setLocation(200, 200);
  }
}

sorry people,
I didn't even used that library much when I ported it. It was a early version of 3.
If somebody could make a pull-request, or fork it that would be great.

Maybe Andreas Schlegel version is also still flying around somewhere to have a look at that...

I might take a look at this. Which renderers does it work with at the moment? Just the default and FX2D?

[transfluxus]

yeah the default should go

@micycle1 did you happen to look into it?
Or does anyone else know a workaround to get drag in drop of 3D objects without a second window?

[micycle1]

@Devostated I looked into it but wasn't able to find an obvious solution.

This is the original code for setup with a JOGL (P2D/P3D) surface:

surfaceType = SurfaceType.JOGL;
setup(((PSurfaceJOGL) surface).getComponent(), applet);

First problem is .getComponent() (which returns a NewtCanvasAWT) returns a null value when the surface has not been initialized off-screen. I tried creating a canvas from the surface's GLWindow (to create a non-null NewtCanvasAWT), as per below, but that didn't fix anything.

surfaceType = SurfaceType.JOGL;
PSurfaceJOGL joglSurface = (PSurfaceJOGL) surface;
GLWindow window = (GLWindow) joglSurface.getNative();
NewtCanvasAWT canvas = new NewtCanvasAWT(window);
setup(canvas, applet);

Also, drop doesn't work with the FX2D renderer either and that's because it doesn't have an AWT canvas object whatsoever... The drag-and-drop feature for JavaFX will need to be completely rebuilt.
