Hi,

If would like to write a kind of "OnEditorOpen" listener. It should be
implemented as an IPartListener. I found out how to register it like this:

PlatformUI.getWorkbench().getActiveWorkbenchWindow().addPart Listener(new
MyListener());

But I'm facing two problems now:

1) When I call this method too early, it crashes Eclipse. So I guess I can
only do the call when eclipse is loaded completely. How can I find out
that it is? Is there a hook or extension point?

2) If there is now extension point, how can I enforce that my plugin is
loaded?

Kind regards

Klaus,

if you want to force your plugin to be activated on platform startup,
simple use the extension point "org.eclipse.ui.startup" in plugin
"org.eclipse.ui".

And that being said, don't use org.eclipse.ui.startup ... See the other
thread on "Surpress Lazy loading of a plugin?"

It's really best not to use it. In RCP apps, you have other options
like the pre and post startup/open methods in your WorkbenchAdvisor and
WorkbenchWindowAdvisor.

Oh. Sorry. Didn't know!
But when this extension point shouldn't be used, how is not possible to
write a plugin for existing applications that requires early startup for
some reason (the usage data collection plugin
"org.eclipse.epp.usagedata.recording" uses this extension point too for
exactly that reason how I believe...)

There are some valid reasons to use it (although most reasons mentioned
in this newsgroup are not appropriate, which is why we strongly
encourage people not to use it).

You are correct, if there was some application data that needed to be
recorded from startup onward, it would seem org.eclipse.ui.startup would
be a good way to start your plugin if it was to be an eclipse plugin (in
RCP you can use the advisors or actually control the OSGi bundle start
order).

The best practice in this case is to make sure that the started plugin
is the minimal set of managers, listeners, and datamodel to record the
needed information. It should not include an UI elements, and probably
not the entire "set of plugins" data model either.
