Eclipse活动不起作用

Question

I am trying to hide elements in the UI by means of activities like this

<plugin>

   <extension
         point="org.eclipse.ui.startup">
      <startup
            class="StartUp">
      </startup>
   </extension>  

   <extension point="org.eclipse.ui.activities">  
<activity id="com.lowcoupling.actitivities.unwantedActionSet1" name="Unwanted Search ActionSet">  </activity>
<activityPatternBinding
      activityId="com.lowcoupling.actitivities.unwantedActionSet1"
      isEqualityPattern="true"
      pattern="org.eclipse.papyrus.infra.discovery.ui.menu.toolbars.discoveryCommand">
</activityPatternBinding>
 </extension>

</plugin>

but when I run this plugin as another EClipse application the button is still there. What am I doing wrong?

Answer 1

The pattern value for activityPatternBinding takes the format:

contributing plug-in id / local id

so you have to work out which plug-in contributes the menu item. Looking at the Eclipse Papyrus download the plug-in appears to be org.eclipse.papyrus.infra.discovery.ui.menu so the pattern is probably:

  pattern="org.eclipse.papyrus.infra.discovery.ui.menu/org.eclipse.papyrus.infra.discovery.ui.menu.toolbars.discoveryCommand">

(assuming isEqualityPattern="true", all the . characters need escaping for the regular expression version)
