Java: Creating an undecorated window with LWJGL

This system property removes the window decorations (title bar, icons, border) from LWJGL applications in window mode.

org.lwjgl.opengl.Window.undecorated=<true|false>

You can specify the property on the command line, when you start the application

java -Dorg.lwjgl.opengl.Window.undecorated=true -jar application.jar

or in your code by setting it manually.

System.setProperty(" org.lwjgl.opengl.Window.undecorated", "true");

See the LWJGL wiki for more hidden property switches.
