Add a pop-up menu item

We can use a pop-up menu extension point to add pop-up menu items to the IBM MQ Explorer.

The following code extract is taken from the plugin.xml file, which we can find in the simple plugin, and shows a basic implementation of the pop-up menu extension point:

<extension
	  id="com.ibm.mq.explorer.sample.simple.object1"
	  name="Object1"
	  point="org.eclipse.ui.popupMenus">
	<objectContribution
		  objectClass="com.ibm.mq.explorer.ui.extensions.MQExtObject"
		  id="com.ibm.mq.explorer.sample.simple.obj1">
		<visibility>
			<and>
				<pluginState
				  value="activated"
				  id="com.ibm.mq.explorer.ui">
				</pluginState>
				<objectClass
				  name="com.ibm.mq.explorer.ui.extensions.MQExtObject">
				</objectClass>
				<objectState
				  name="PluginEnabled"
				  value="com.ibm.mq.explorer.sample.simple">
				</objectState>
			</and>
		</visibility>
		<action
		  label="Simple: Sample action on any MQExtObject"
		  class="com.ibm.mq.explorer.sample.simple.MenuActions"
		  menubarPath="additions"
		  id="com.ibm.mq.explorer.sample.simple.obj.action1">
		</action>
	</objectContribution>
</extension>

We can add menu items by using the Eclipse Platform extension point org.eclipse.ui.popupMenus. The <visibility> attribute in the preceding extract contains the elements that control the conditions under which the pop-up menu item is displayed. These conditions include tests on the plug-in state, the type of object, and the state of the object. For example, a content menu item can be displayed for local queues only, or for remote queue managers only.
