窗口标题是否可以在具有兼容性层的Eclipse 4应用程序中包含核心插件的版本号？

Question

In a mixed mode Eclipse RCP application, I'd like to change the application window title to something like "Great App v1.3.22".

I basically have application (3.x based) and product (4.5 (Mars) based) split up into two plugins (following a helpful blog post describing how to use 3.x views in Eclipse 4, I need the CNF).

At the moment, the title is "got" from the org.eclipse.core.runtime.products extension point defined in the product plugin :

<extension
  id="my_product_id"
  point="org.eclipse.core.runtime.products">
  <product
    name="Great App"
    application="my.application">
  </product>
</extension>

Can I use a variable in the <product name> property? If so, what variables are available? Or can this be achieved by "overriding" the window title via the Trimmed Window entry in Application.e4xmi , and again what variables would be available? Or do I have to resort to ancient ways and set the title programmatically in the old ApplicationWorkbenchWindowAdvisor (which, however, wouldn't be available if I was able to switch to a pure E4 app once the CNF is available as a native E4 plugin)?

There are no variables you can use.

You can change the main window title in the LifeCycle class. The @ProcessAdditions method is the earliest you can do this:

@ProcessAdditions
public void processAdditions(MApplication app, EModelService modelService, IApplicationContext applicationContext)
{
  MWindow window = (MWindow)modelService.find("id of main trimmed window", app);

  window.setLabel("new text");
}

I am not sure where you want to get the version from. One possibility is a property in the product definition:

<extension
  id="my_product_id"
  point="org.eclipse.core.runtime.products">
  <product
    name="Great App"
    application="my.application">
     <property
           name="version"
           value="1.3.22">
      </property>
   </product>
</extension>

You will have to maintain this property manually or do something in your build to set it.

You can access this using the IApplicationContext

applicationContext.getBrandingProperty("version")
