Question

我想在java中的Jframe中嵌入microsoft字。这就是为什么我有以下代码：

public class AbrirWordJFrame {
    static OleClientSite clientSite;
    static OleFrame frame;

    public static void main(String[] args) {
        final Display display = new Display();
        final Shell shell = new Shell(display);

        JFrame jframe=new JFrame("Mi jframe");
        final Canvas canvas=new Canvas();
        jframe.getContentPane().add(canvas);
        jframe.setSize(800, 600);
        jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        jframe.setVisible(true);

        System.out.println("Before Async"); 

        display.asyncExec(new Runnable() {
            public void run() {
                System.out.println("In Async method");
                Shell shell = SWT_AWT.new_Shell(display, canvas);
                shell.setSize(800, 600);

                //abrimos un word
                shell.setText("Word Example");
                shell.setLayout(new FillLayout());
                try {
                    frame = new OleFrame(shell, SWT.NONE);
                    //esto abre un documento existente
                    clientSite = new OleClientSite(frame, SWT.NULL, new File("prueba.doc"));
                    //esto abre un documento en blanco
//                  clientSite = new OleClientSite(frame, SWT.NONE, "Word.Document");
                    addFileMenu(frame);
                } catch (SWTError e) {
                    System.out.println("Unable to open activeX control");
                    display.dispose();
                    return;
                }
                //fin abrimos un word
                //abrimos un navegador
//              Browser browser = new Browser(shell, SWT.NONE);
//              browser.setLayoutData(new GridData(GridData.FILL_BOTH));
//              browser.setSize(800, 600);
//              browser.setUrl("http://www.google.com");
                //fin abrimos un navegador
                shell.open();

            }
        }); 

       // display d= new Display(new runnable);


        //el titulo
//      shell.setText("Word Example");
//      shell.setLayout(new FillLayout());
//      try {
//          frame = new OleFrame(shell, SWT.NONE);
//          //esto abre un documento existente
//          clientSite = new OleClientSite(frame, SWT.NULL, new File("prueba.doc"));
//          //esto abre un documento en blanco
////            clientSite = new OleClientSite(frame, SWT.NONE, "Word.Document");
//          addFileMenu(frame);
//      } catch (SWTError e) {
//          System.out.println("Unable to open activeX control");
//          display.dispose();
//          return;
//      }
//      shell.setSize(800, 600);
//      shell.open();
//      
        while (!shell.isDisposed()) {
            /*if (!display.readAndDispatch())
                display.sleep();*/
        }
        display.dispose();
    }

    static void addFileMenu(OleFrame frame) {
        final Shell shell = frame.getShell();
        Menu menuBar = shell.getMenuBar();
        if (menuBar == null) {
            menuBar = new Menu(shell, SWT.BAR);
            shell.setMenuBar(menuBar);
        }
        MenuItem fileMenu = new MenuItem(menuBar, SWT.CASCADE);
        fileMenu.setText("&File");
        Menu menuFile = new Menu(fileMenu);
        fileMenu.setMenu(menuFile);
        frame.setFileMenus(new MenuItem[] { fileMenu });

        MenuItem menuFileOpen = new MenuItem(menuFile, SWT.CASCADE);
        menuFileOpen.setText("Open...");
        menuFileOpen.addSelectionListener(new SelectionAdapter() {
            public void widgetSelected(SelectionEvent e) {
                fileOpen();
            }
        });
        MenuItem menuFileExit = new MenuItem(menuFile, SWT.CASCADE);
        menuFileExit.setText("Exit");
        menuFileExit.addSelectionListener(new SelectionAdapter() {
            public void widgetSelected(SelectionEvent e) {
                shell.dispose();
            }
        });
    }

    static void fileOpen() {
        FileDialog dialog = new FileDialog(clientSite.getShell(), SWT.OPEN);
        dialog.setFilterExtensions(new String[] { "*.doc" });
        String fileName = dialog.open();
        if (fileName != null) {
            clientSite.dispose();
            clientSite = new OleClientSite(frame, SWT.NONE, "Word.Document", new File(fileName));
            clientSite.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
        }
    }
}

我收到以下例外情况：

但asyncExec方法不是调用runnable类的run方法。我在互联网上搜索过很多东西，一无所获。请帮我。

您没有运行SWT事件调度循环，您必须为asyncExec（以及SWT的许多其他部分）运行此操作。

你有：

while (!shell.isDisposed()) {
    /*if (!display.readAndDispatch())
        display.sleep();*/
}

那些注释掉的行是事件调度循环。你必须致电：

while (!shell.isDisposed()) {
  if (!display.readAndDispatch())
    display.sleep();
}

但是你正在混合使用Swing和SWT - 你不应该这样做，因为很难正常工作。使用Swing或SWT但不能同时使用两者。您可以使用SWT_AWT类从SWT调用Swing代码，但这应该是最后的手段。

asyncExec方法不调用Runnable类的run方法
