Is it possible to make a transparent window?

schmidt

I'm making a simple draw sketch, but i wan't to be able to paint on the windows/apps that are beneath processing. Similar to a transparent layer in photoshop. I've tried the ghost library, but it only makes a screenshot on whats beneath

Any ideas? :-)

MenteCode

There are two options that I've found. One is not as clean, code-wise, but the other is incompatible with Java 6.

1) More likely to work.

import com.sun.awt.AWTUtilities;

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

2) Cleaner code.

void setup() {
  frame.removeNotify();
  frame.setUndecorated(true);
  frame.setOpacity(0.5f);
  frame.addNotify();
}

Just have the lines of your choice written in your setup() function, and you'll be good to go. ;)

Thanks guys, tried mentecode's version and it worked the best.

PhiLho, thanks. The topic "transparent window with solid graphics" look really interesting, but the link you posted there was broken. Do you mind sharing it again? :-)

Thanks
