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?
How long does the drawing itself take to do? I'd guess less time than
retrieving the data? So you might want to stop when the data has been
fetched? What object does the fetching? It could send either a
message directly, or a notification...
