Reparent X11 window on a JFrame or a JPanel?

Question

In order to embed a C/C++ X11 application into another Java application, is it possible to reparent the X11 top level widget in:

a JFrame or a JWindow (catching the X11 window ids of their X11 peers using package sun.awt.x11)?
or a JPanel?

I would prefer reparent with a JPanel but I'm not sure it's possible.

Hello, I don't understand why I get a -1 vote. What is the problem with my question? — paranoia25, Aug 07 '12 at 11:46
First question: can you embed the C++ application in the JVM using JNI, or do they have to remain as separate applications? It's easier to do this if you have the apps linked together. — Ernest Friedman-Hill, Aug 14 '12 at 12:35
Never tried this, but maybe this method will help: http://javasourcecode.org/html/open-source/jdk/jdk-6u23/sun/awt/X11/XPanelPeer.html#xembed(long) — Konstantin V. Salikhov, Aug 15 '12 at 08:07
First question: no they have to remain as separate applications. Second question: no OpenGL involved. — paranoia25, Aug 15 '12 at 09:59

I searched and found:

A recursive function that will search (starting from the root window) for a window with the desired name

Window windowWithName(Display *dpy, Window top, char *name)
{
        Window *children, dummy;
        unsigned int nchildren;
        unsigned int i;
        Window w = 0;
        char *window_name;

        if (XFetchName(dpy, top, &window_name) && !strcmp(window_name, name))
                return (top);

        if (!XQueryTree(dpy, top, &dummy, &dummy, &children, &nchildren))
                return (0);

        for (i = 0; i < nchildren; i++)
        {
                w = windowWithName(dpy, children[i], name);
                if (w)
                        break;
        }
        if (children)
                XFree((char *) children);
        return (w);
}

You can always open a java.net.Socket to port 6000 or so and speak X11 yourself.
code that might help

reference, hope this help
NOTE: package sun.awt.x11 is no more in jdk7

Thanks! I'm going to try your solution. Keep inform. – paranoia25 Sep 03 '12 at 14:27 — paranoia25, Sep 03 '12 at 14:27
