QTableView Show/Hide Row Performance Test / 10-10-2011 / Phil

See the test QTreeView dialog image below. This table has 10,000 rows. These are the results from toggling the "Show all rows" checkbox. When that checkbox is off, half the rows are hidden (every other group of 10 rows). It takes about 1.5 second to hide 5000 rows, and 1.0 seconds to reshow them. [On Phil's new 64-bit machine]. This speed is good -- this isn't demonstrating the problem we are having with the SlotQDlgTable Qt4 port.
