Calling GLWindow.setAlwaysOnTop() does not result in the GLWindow being on top of all other windows, as expected. This happens on Mac OS X (tested with 10.9.5). Works fine on Windows (10) and Ubuntu (12.04). The following code demonstrates the issue: https://github.com/codeanticode/jogl2-tests/blob/master/src/test/windows/WindowTopNEWT.java
commit 3d2765f0bb752debd7784f717eeac4c9eb500d5a: - The NSWindow level must be set at window creation - Levels are - aontop: kCGMaximumWindowLevel - aonbottom: kCGDesktopIconWindowLevel (w/ input) - normal: NSNormalWindowLevel - Hence we need to recreate the NSWindow if toggling the state, similar to opaque .. etc.
