[Sorry if this is a repeat. I sent this out a couple of days ago and
didn't see it show up on the list, so I figured it disappeared into the
ether. Anyways...]
Is there a way to tell when all subviews of a certain view have
completed drawing themselves?
I have a NSWindowController managing a window that contains a NSTabView
that contains NSTableViews as subviews. When I switch to a new tab
(usually the first time), it's possible that the data source supplying
the table could take a little while to get its data in order. I'd like
to display a spinning NSProgressIndicator while all this is going on
until the views finish drawing.
I have no problem starting up the indicator in the tab view's
tabView:willSelectTabViewItem: delegate method, but I don't know where
to stop it. Ideas?
