eclipse开发视图

打开eclipse 或者myeclipse 选中任意位置 new puginproject 输入工程名称 其他默认 选择向导里面的一项 plugin in with a view 右边的框中 有一项 我们看到右边的拓展点 是 我们来开发一个播放MP3和视频的视图插件 我们先到 pugin.xml里面 添加拓展 <extension 拓展点就是 eclipse加载的时候 要判断加载的是视图还是其他的东西 同时也是要说明操作这些拓展时 要做什么操作 操作就由类去完成 视图操作类 必须继承ViewPart类 播放视频的视图类 package media.views; import java.io.File; import org.eclipse.jface.action.IMenuListener; /** public class MediaView extends ViewPart { /** /** container = new Composite(parent, SWT.NULL); Button button1 = null; @Override try { // 呼叫function URL()並且傳入參數 catch (MalformedURLException urlE) { } }); container.getShell().getDisplay().asyncExec(new Runnable() { } // 取得windows media player之後將視窗嵌入應用程式 oleCtrlSite.setVisible(true); // 建立操作ocx內部方法與變數的實體 // 這個我也還沒查出來><"，有看到的話在上來補槍 return automation; public void setPostion(int s) @Override 播放歌曲的类 package media.views; import java.io.File; import org.eclipse.swt.SWT; /** public class SongView extends ViewPart { /** container = new Composite(parent, SWT.NULL); public void mouseDoubleClick(MouseEvent arg0) { public void mouseDown(MouseEvent arg0) { public void mouseUp(MouseEvent arg0) { @Override }); { @Override }); oleCtrlSite.setVisible(true); // 建立操作ocx內部方法與變數的實體 } try { // 呼叫function URL()並且傳入參數
