[SOLVED] JMEDesktop with scene behind : JFrame is not visible after add

Troubleshooting gui
1

Hello all,



EDIT: maybe related to http://www.jmonkeyengine.com/jmeforum/index.php?topic=6287.0 ?



I used some RubiksCube class found in the forum at http://www.jmonkeyengine.com/jmeforum/index.php?topic=6478.0.



I now try to customize it by adding a JMEDesktop on top of the window, thus showing regular Swing controls/debug infos.

This is for a thesis project and want to keep it as “clean” as possible, that is by not using fancy 3D things and still allow simple raw data display.



My problem is that i create a yellow transparent desktop, put it on top of the window, try to add a javax.swing.JFrame but it is not visible?!



Code that might cause problem :

    protected void simpleInitGame() {
// removed code for reading, see 7z file !

        // create a node for ortho gui stuff
        guiNode = new Node("gui");
        guiNode.setRenderQueueMode(Renderer.QUEUE_ORTHO);

        // move the 'default' keys (debug normals, toggle lighting, etc.) to a separated input handler
        InputHandler handlerForDefaultKeyActions = input;
        // remove the first person nested handlers
        handlerForDefaultKeyActions.removeAllFromAttachedHandlers();
        // create a new handler for our input
        input = new InputHandler();
        // add the default handler as a child
        input.addToAttachedHandlers( handlerForDefaultKeyActions );

        // Create 3D desktop and attach it to the gui node
        final JMEDesktop desktop = new JMEDesktop("desktop", 1280, 100, input);
        desktop.getLocalTranslation().set(display.getWidth() / 2, display.getHeight(), 0);
        guiNode.attachChild(desktop);

        // perform all the swing stuff in the swing thread
        // (Only access the Swing UI from the Swing event dispatch thread!
        // See SwingUtilities.invokeLater()
        // and http://java.sun.com/docs/books/tutorial/uiswing/concurrency/index.html for details.)
        SwingUtilities.invokeLater(new Runnable() {

            public void run() {
                // Set desktop style
                desktop.getJDesktop().setBackground(new Color(1, 1, 0, 0.2f));

                // Create frame and attach it
                final FrameControls controlPanel = new FrameControls();
                desktop.getJDesktop().add(controlPanel);
                controlPanel.setLocation(200, 200);
                controlPanel.setSize(1000, 1000);
                controlPanel.setVisible(true);  
            }
        });

        // don't cull the gui away
        guiNode.setCullMode(SceneElement.CULL_NEVER);
        // gui needs no lighting
        guiNode.setLightCombineMode(LightState.OFF);
        // update the render states (especially the texture state of the deskop!)
        guiNode.updateRenderState();
        // update the world vectors (needed as we have altered local translation of the desktop and it's
        //  not called in the update loop)
        guiNode.updateGeometricState(0, true);

        // finally show the system mouse cursor to allow the user to click our button
        MouseInput.get().setCursorVisible(true);
    }

Just noticed error "java.lang.IllegalArgumentException: adding a window to a container"…

I now have replaced my FrameControls by a PanelControls, error is gone but is still not visible :frowning:

Problem was that location was not correctly set. Fixed code :


        // Create 3D desktop and attach it to the gui node
        final JMEDesktop desktop = new JMEDesktop("desktop", display.getWidth(), c_desktopHeight,input);
        guiNode.attachChild(desktop);
        desktop.getLocalTranslation().set(display.getWidth() / 2, display.getHeight()-c_desktopHeight/2, 0);

        // perform all the swing stuff in the swing thread
        // (Only access the Swing UI from the Swing event dispatch thread!
        // See SwingUtilities.invokeLater()
        // and http://java.sun.com/docs/books/tutorial/uiswing/concurrency/index.html for details.)
        SwingUtilities.invokeLater(new Runnable() {

            public void run() {
                // Set desktop style
                desktop.getJDesktop().setBackground(new Color(1, 1, 0, 0.2f));

                // Create frame and attach it
                final PanelControls controlPanel = new PanelControls();
                desktop.getJDesktop().add(controlPanel);
                controlPanel.setLocation(0, 0);
                controlPanel.setSize(display.getWidth(), c_desktopHeight);
                controlPanel.setVisible(true);
            }
        });
