Problem with selecting thousands of items in the hub's userlist

[eMTee]

Selecting 1000+ of users (or select all with Ctrl-A) in a hub's userlist takes extremly long (30+ seconds) and the gui freezes until its done. Seems the bug introduced in 0.689...

The same occurs when manipulating large lists of files/items either selecting for download, adding to queue, changing priority or using 'move' to change the destination directory.

confirmed, it seems that the UI tries to update itself thousand times (for thousand users) instead of only once...

freezes fixed by using async calls.

it still doesn't seem optimal that list views send as many "selection changed" messages as the number of selected items; some kind of caching, like <http://msdn.microsoft.com/en-us/library/bb774735(VS.85).aspx#Virtual_ListView_Style>, could solve it but that would require many changes...

while virtual list views would still be preferable, this has been mitigated for now in rev 2963 by ignoring list selection change messages and updating the status bar once every half second instead.

Fixed in DC++ 0.800.
