I am trying to write a plugin that will be notified every time an editor
is opened. So far I have implemented an IPartListener and on startup
(using the ui.startup extension point) I add the IPartListener to every
"page" in the workbench.
IWorkbenchWindow window =
PlatformUI.getWorkbench().getActiveWorkbenchWindow();
if (window != null) {
IWorkbenchPage[] pages = window.getPages();
for (int i = 0; i < pages.length; i++) {
IWorkbenchPage p = pages[i];
p.addPartListener(new MyPartListener());
}
}
this seem to work. However, editors that are already opened are missed.
Is there a way to get these editors added?
Thanks,
Ian

Even better: use IPartListener2.
