"The frame is decorated" error message

rumlac

Hello,

I am using processing 2.2.1, when I try and run an example script, the following error message is appearing:

Exception in thread "AWT-EventQueue-0" java.awt.IllegalComponentStateException: The frame is decorated

I have tried adding

  frame.removeNotify();
  frame.setUndecorated(true);
  frame.addNotify();   

to the set up but with no luck.

Hopefully someone can point me in the right direction.

Thanks!

Does that happen with all example scripts? Maybe the screen capture frame is the culprit.

Got this old example working in Processing 2.2.1: >-)

void setup() {

void draw() {

  fill(#FF0000);
  text(frameCount, width - 100, 40);

  fill(#0000FF);
  translate(frameCount % width, height >> 1);

String removeFrameBorder(String gfx) {
  if (!isGL()) {
    frame.removeNotify();
    frame.setUndecorated(true);
    frame.addNotify();
  }

  return gfx;
}

Hi, no it only happens when using examples from the screenCapturer lib (http://www.onformative.com/lab/screencapturer/) I assume this was built for a previous version of processing / java. I'll give that a go ^ Thanks

Hi, just played around with that but still no luck, I think it has something to do with the fact that it is not opening a translucent window like it should. The script for the sketch is:

import com.onformative.screencapturer.*;

ScreenCapturer capturer;
void setup() {
  size(600, 600);
  capturer = new ScreenCapturer(width, height, 30);
}

void draw() {
  image(capturer.getImage(), 0, 0);
}

I thought about using the following but was unable to get a result

import com.sun.awt.AWTUtilities;

void setup() {
  size(500,500);
  frame.removeNotify();
  frame.setUndecorated(true);
  AWTUtilities.setWindowOpacity(frame,0.5f);
  frame.addNotify();
}

Thanks again.
