[FIXED] JavaFX setting window Always on top with JNA lib, windows os

Issue

I have to put my application transparent window over the top of every application//not just within application < Im aware that i can set modality on stage and put it on top bud thats not what i look for >// (same functionality as swing's setAlwaysOnTop(true)),bud since this is JavaFX application i dont have this option yet.So i decided to go native, i have JNA class

public interface Kernel32 extends StdCallLibrary {

    public static class WinOnTop extends Structure {

        public HWND  hWnd;
        public HWND  hWndInsertAfter;
        public int X;
        public int Y;
        public int cx;
        public int cy;
        public int uFlags;

        @Override
        protected List getFieldOrder() {
            return Arrays.asList(new String[]{"hWnd", "hWndInsertAfter", "X", "Y", "cx", "cy", "uFlags"});
        }

    }

    boolean SetWindowPos(HWND hWnd, HWND hWndInsertAfter, int X, int Y, int cx,
            int cy, int uFlags);

}

And resource i use to create it is

http://msdn.microsoft.com/en-us/library/windows/desktop/ms633545%28v=vs.85%29.aspx

In my main i create object as:

 public static Kernel32 kernel;

    static{
        kernel=(Kernel32)Native.loadLibrary("Kernel32", Kernel32.class);
    }

This is my first time that i try to add some native functionality into my application.

My question is how do i preceed? How can i say that THIS IS THE STAGE THAT I WANT TO APPLY THIS FUNCTIONALITY TO , i really need to point to the right direction as i dont know what im doing atm with JNA

I have seen some tutotial on how to acess time bud its only working with simple variable,How can i connect thos function with my Transparent Stage?

Solution

Don't use JNA, use Java8u20 or any other subsequent version, which has a JavaFX always on top feature.

stage.setAlwaysOnTop(true);

There is a nice blog post by Carl Dea on always on top.
