I found a hack that does get this to work, but as it involves "kicking" the run
loop during a modal session, I dunno if it's really legal.
Trying to force the thumb view to display in the modal session doesn't work, so
my guess is that a timer is used to fetch the the page to be rendered as a
thumbnail and that's what's blocking, not the repaint. This code in the modal
dialog's window controller.
NSModalSession session = [NSApp
beginModalSessionForWindow:[self window]];
NSInteger result;
while( 1 )
{
result = [NSApp runModalSession:session];
if( result != NSRunContinuesResponse )
break;
// force run loop to run in standard mode so that thumbs get
updated:
[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode
beforeDate:[NSDate date]];
}
[NSApp endModalSession:session];
