Examples with Toolkit java.awt.Toolkit used on opensource projects

Example 1 with Toolkit

use of java.awt.Toolkit in project jdk8u_jdk by JetBrains.

the class Util method createEmbeddedFrame.

public static Frame createEmbeddedFrame(final Frame embedder) throws ClassNotFoundException, NoSuchFieldException, IllegalAccessException, NoSuchMethodException, InstantiationException, InvocationTargetException {
    Toolkit tk = Toolkit.getDefaultToolkit();
    FramePeer frame_peer = (FramePeer) embedder.getPeer();
    System.out.println("frame's peer = " + frame_peer);
    if ("sun.awt.windows.WToolkit".equals(tk.getClass().getName())) {
        Class comp_peer_class = Class.forName("sun.awt.windows.WComponentPeer");
        System.out.println("comp peer class = " + comp_peer_class);
        Field hwnd_field = comp_peer_class.getDeclaredField("hwnd");
        hwnd_field.setAccessible(true);
        System.out.println("hwnd_field =" + hwnd_field);
        long hwnd = hwnd_field.getLong(frame_peer);
        System.out.println("hwnd = " + hwnd);
        Class clazz = Class.forName("sun.awt.windows.WEmbeddedFrame");
        Constructor constructor = clazz.getConstructor(new Class[] { Long.TYPE });
        return (Frame) constructor.newInstance(new Object[] { hwnd });
    } else if ("sun.awt.X11.XToolkit".equals(tk.getClass().getName())) {
        Class x_base_window_class = Class.forName("sun.awt.X11.XBaseWindow");
        System.out.println("x_base_window_class = " + x_base_window_class);
        Method get_window = x_base_window_class.getMethod("getWindow", new Class[0]);
        System.out.println("get_window = " + get_window);
        long window = (Long) get_window.invoke(frame_peer, new Object[0]);
        System.out.println("window = " + window);
        Class clazz = Class.forName("sun.awt.X11.XEmbeddedFrame");
        Constructor constructor = clazz.getConstructor(new Class[] { Long.TYPE, Boolean.TYPE });
        return (Frame) constructor.newInstance(new Object[] { window, true });
    }
    throw new RuntimeException("Unexpected toolkit - " + tk);
}

Example 2 with Toolkit

use of java.awt.Toolkit in project jdk8u_jdk by JetBrains.

the class MultiResolutionImageTest method testImageLoaded.

static void testImageLoaded(Image image) {
    Toolkit toolkit = Toolkit.getDefaultToolkit();
    int flags = toolkit.checkImage(image, IMAGE_WIDTH, IMAGE_WIDTH, new SilentImageObserver());
    if ((flags & (ImageObserver.FRAMEBITS | ImageObserver.ALLBITS)) == 0) {
        throw new RuntimeException("Image is not loaded!");
    }
}

private static Method getScalableImageMethod(String name, Class... parameterTypes) throws Exception {
    Toolkit toolkit = Toolkit.getDefaultToolkit();
    Method method = toolkit.getClass().getDeclaredMethod(name, parameterTypes);
    method.setAccessible(true);
    return method;
}

Example 4 with Toolkit

use of java.awt.Toolkit in project jdk8u_jdk by JetBrains.
