如何将menuListener添加到菜单中？

Question

如何将menuListener添加到由以下xml生成的菜单中，以便在焦点位于特定菜单（未点击）时我可以执行某些操作。

<extension
         point="org.eclipse.ui.editorActions">
      <editorContribution
            targetID="net.sourceforge.texlipse.TexEditor"
            id="net.sourceforge.texlipse.editor.editorContribution">
         <menu
               label="&amp;TTS Settings"
               id="net.sourceforge.texlipse.menus.tts">
            <separator name="sourceGroup"/>
            <separator name="latexGroup"/>
            <separator name="commentGroup"/>
            <separator name="spellGroup"/>
         </menu>     

          <action
                class="net.sourceforge.texlipse.actions.TTSPdfModeAction"
                icon="icons/start.png"
                id="net.sourceforge.texlipse.actions.TTSPdfModeAction"
                definitionId="net.sourceforge.texlipse.commands.PDF"
                label="&amp;PDF"
                menubarPath="net.sourceforge.texlipse.menus.tts/sourceGroup"
                style="push"
                toolbarPath="latexGroup"
                tooltip="PDF"/>                                       
           <action
                class="net.sourceforge.texlipse.actions.TTSStopAction"
                icon="icons/stop.png"
                id="net.sourceforge.texlipse.actions.TTSStopAction"
                definitionId="net.sourceforge.texlipse.commands.TTSStop"
                label="&amp;Stop"
                menubarPath="net.sourceforge.texlipse.menus.tts/sourceGroup"
                style="push"
                toolbarPath="latexGroup"
                tooltip="Stop"/>      
      </editorContribution>
   </extension>
