[SOLVED] Change window settings?

I seen in some documentation that they use DislpaySettings.createWindow(Whatever here); to set the resolution, bitdetph, fullscreen mode of a window. That didn’t work with jme3 when I tried it so I read around forum and the javadoc and seen that there is not a com.jme3.settings.DisplaySettings any more, but I can’t seem to find what it is I need for changing the window settings. To try and avoid hours of searching I figured I’d ask if anyone knows how I could do this? I’m a newbie and still learning all the ins and outs of jme so you’ll have to bare with me. I’m sure to have some more obvious questions.

Thanks a ton.
