     Delay the execution of filters, sorters and proxyRoles until the next event loop.
     This can be used as an optimization when multiple filters, sorters or proxyRoles are changed in a single event loop.
     They will be executed once in a single batch at the next event loop instead of being executed in multiple sequential batches.
 
-    By default, the SortFilterProxyModel is not delayed, unless the SFPM_DELAYED is defined at compile time.
