Description Jesse Glick 2009-07-02 19:22:08 UTC
Currently if you want to find a list of open TC's in a Mode, you can call Mode.getTopComponents() and check isOpened()
on each. Unfortunately, loading non-open TC's can involve a lot of work.

The fix for issue #156647 requires using WindowManager.modes followed by Mode.topComponents to iterate open editor TC's
in visible order. This can cause lengthy delays when closing projects - see the profiler snapshot, where the window
system is loading the Bugzilla window, which I have opened maybe once and never again.

An API method Mode.getOpenTopComponents, which did not even try to load serialized data and classes from TC's known to
not be open, would be useful here.

fixed, core-main cbc223a0ed28

i cannot add new methods to Mode interface but you can use WindowManager.getOpenedTopComponents(Mode)
