• 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
    Extensions Used
    org.eclipse.ui.views

    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
             point="org.eclipse.ui.views">
          <category
                name="LH娱乐图"
                id="media">
          </category>
          <view
                name="LH电影视图"
                icon="icons/sample.gif"
                category="media"
                class="media.views.MediaView"
                id="media.views.MediaView">
          </view>
          <view
                name="LH歌曲视图"
                icon="icons/sample.gif"
                category="media"
                class="media.views.SongView"
                id="media.views.SongView">
          </view>
       </extension>
       <extension
             point="org.eclipse.ui.perspectiveExtensions">
          <perspectiveExtension
                targetID="org.eclipse.ui.resourcePerspective">
             <view
                   ratio="0.5"
                   relative="org.eclipse.ui.views.TaskList"
                   relationship="right"
                   id="media.views.MediaView">
             </view>
              <view
                   ratio="0.5"
                   relative="org.eclipse.ui.views.TaskList"
                   relationship="right"
                   id="media.views.SongView">
             </view>
          </perspectiveExtension>
       </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
