Hook for GMF editor startup? [message #491426]

Hi there,

I need a way to execute a function at a point in time before any GEF/GMF
editor has initialized. This way I want to globally register some
listeners and stuff.

So far I used the org.eclipse.ui.startup extension point to do this.
However, the earlyStartup method is only called after all Workbench
stuff was initialized. This might be *after* an GEF/GMF Diagram editor
has been initialized. Is there any hook available that lets me execute a
method call right before the first diagram editor opens up?

Not nure whether this is a GEF or GMF related question.

Example: I want to write a listener that gets informed about any
collapse or expand events or compartments in graphical editors,
regardless of the actual editor. Hence I have an IPartListener, that
listens to changes of the active editor and registers a
ResourceSetListener to the currently active editor. However, in my
current setup, no Notifications are fired for already open editors at
startup.

Cheers,
Hauke

Hi,

Why not hookup to your plugin start(BundleContext ctx) methods or
workbench preWindowOpen(); ?

Because it's not guaranteed that my plugin is started at all.

Hello Hauke,

It should be started before instantiating diagram editor described there.
