ObjectListView

[ppw]

Hello,

I was wondering if anyone knows what Everything does to display its results and makes scrolling fast, since right now I'm using ObjectListView/FastObjectListView for my app which among other things retrieves image and video metadata from many files, but dear lord, the scrolling performance is abhorrent.

Thanks

Everything uses a custom SysListView32 control.

Everything creates a standard SysListView32 control, immediately overrides the default windows proc (SetWindowLongPtr) and handles all window messages.
This includes emulating all LVM_* messages.



Everything doesn't update the display immediately on scrolling. (UpdateWindow)
Instead the listview is invalidated. (InvalidateRect)
Updating the listview on scroll can cause slow scrolling and miss scroll events.

Please make sure your control is not updating on scroll.
