I want to be able to create a second window. The problem is I want the user to be able to close the second window, but doing so closes both the second and main frame. Is there a way I can prevent this? PWindow win; public void settings() { size(320, 240); } void setup() { win = new PWindow()…

This did the trick for me: PWindow win; public void settings() { size(320, 240); } void setup() { surface.setLocation(20,20); win = new PWindow(); } void draw() { background(255, 0, 0); fill(255); rect(10, 10, frameCount, 10); } void mousePressed() { println("mousePressed in pri…

Above link gives the example SetDefaultCloseEvent sketch, which uses jogamp.newt.Window.setDefaultCloseOperation() to set a default close policy.

Actually, what is passed to setDefaultCloseOperation() is either the enums from com.jogamp.nativewindow.WindowClosingProtocol.WindowClosingMode: http://JogAmp.org/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/nativewindow/WindowClosingProtocol.WindowClosingMode.html Or the constants from …

Wouldn’t that prevent the user from closing the second window?

Ah, I get it now. It makes the window invisible, and pauses the sketch but it can be made visible again easily. OP is essentially running two PApplets on the same JVM. My method terminates the secondary sketch but keeps the JVM open so the primary one can stay running. So OP has the choice - eithe…

For my application hiding the second window is preferred to terminating it, thanks guys I’m also running into an issue where I want to apply a shader filter to both windows. Both are set to use P2D. The second window sporadically crashes with errors when trying to do things like filter(blur) usin…

That PWindow::exit() method is never called back. Instead, move that exit() to the main sketch PApplet in order to avoid that “ThreadDeath”: @Override void exit() { win.dispose(); super.exit(); }
