Re: Embedding FileDiff in another application - next problem

["Stephen Kennedy" <stevek gnome org>]

Hi Szilveszter, (I meant to keep this discussion on meld-list!)

Ah, the deferred execution is catching you out. Each doc has a
scheduler which does some work when the app is otherwise idle. So
set_files doesn't actually do anything until the gtk idle callbacks
happen.

Call doc.scheduler.complete_tasks() to flush the work queue before
calling set_editable. Or you might prefer to add a task to the docs
scheduler so that your app won't block reading the files before the
gui comes up. You can add any callable.
e.g. doc.scheduler.add_task( lambda : [t.set_editable(False) for t in
doc.textview] )

Stephen.
