I have a simple barebones Workbench window in which I added a "main" menu
and menu item by extending "actionSets" as show below. However, I would
like to get a handle on the menu item Action object so that I could
programatically enable and disable the Action.
I have seen explanations on how you can control the "enablement" of the
(actionSet) menu item through the "enablesFor" and "enablement" xml
elements of the plugin.xml. But these mechanisms only control the
enablement with relation to "selection" of something else. This is not
what I am looking for.
I would like to be able to enable or disable a menu item at will when, for
example, a button in a view is pressed or because of some other
application specific event not necessarily related to a "Selection event".
Is anyone aware of a way to do this?
... .
<extension
point="org.eclipse.ui.actionSets">
<actionSet
label="%actionset.label"
visible="true"
id="com.ibm.commerce.telesales.actionSet">
<menu
label="%menu.order"
id="telesales.order">
<separator
name="TeleSalesOrderGroup">
</separator>
<separator
name="TeleSalesOrderFindGroup">
</separator>
</menu>
<action
label="%menu.order.find"
icon="icons/search.gif"
tooltip="%menu.order.find.tooltip"
class="com.ibm.commerce.telesales.ui.actions.FindOrderAction "
menubarPath="telesales.order/TeleSalesOrderFindGroup"
id="com.ibm.commerce.telesales.ui.action.order.find">
</action>... .
Another related question is, when I use the following code to get a handle
on my menu item, item turns out to be null. It seems like the Active
Workbench Window is not aware of the menu or menu item that I added
through extension. Can someone please tell me what is the right approach
to get a handle.
IMenuManager mm =
TeleSalesUIPlugin.getPlugin().getWorkbench().getActiveWorkbe nchWindow().getActionBars().getMenuManager();
IContributionItem item =
mm.findUsingPath(" telesales.order/com.ibm.commerce.telesales.ui.action.order.f ind ");
System.out.println("item = " + item);
any help will be appreciated.
thanks

Thanks Simon, that helped.
So now my action handler class not only implements
IWorkbenchWindowActionDelegate but also IActionDelegate2 interface.
