SWT 中嵌入Word 控件应用

利用WebOffice进行Word控件的应用，源码如下：

效果图如下：

package com.edocbase.desktop.word;

import java.io.File;
import java.util.HashMap;
import java.util.Iterator;

import org.eclipse.swt.SWTException;

import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Composite;
