Question

I am using menuContributions+popup to show a context menu in my plugin.xml. I need to limit it’s visibility only to

1. certain type of Project(e.g. Dynamic Web Project) (Menu should appear on right click of only parent project folder) and
2. a particular folder(e.g Web Content) and it’s sub folders inside the Project Folder structure.

I was able to achieve the 1) condition to some extent by using

<menuContribution locationURI="popup:common.new.menu?after=additions">
            <command
                label="Web Wiz"
                commandId="commandId"
                icon="icons/sample.gif">
               <visibleWhen>
                  <with  variable="selection">
                            <iterate ifEmpty="false"
                        operator="or">
                     <instanceof
                           value="org.eclipse.core.resources.IProject"/>
                  </iterate>
                  </with>
               </visibleWhen>
            </command>
        </menuContribution>

but it appears for all kinds of projects…I need to limit it to only a Dynamic Web Project, so what should I add to meet this requirement in plugin.xml?

Answer 1

1. Add a propertyTester that will test your project type.
2. Use that tester in the visibleWhen

You can read about property-tester at the eclipse help, or at the extension help itself 🙂

EDIT – Check this one out as well – http://wiki.eclipse.org/Command_Core_Expressions#Property_Testers (especially the ResourcePropertyTester, which can provide you a built-in implementation that you can use)
