Title: Mouse wheel scrolling doesn't work after drag and drop (Version 3.9.2)
Post by: kakkou on November 20, 2015, 04:38:19 AM

" Example 11 - Drag & Drop" but it occurs.

UIDragDropItem makes mDragScrollView disable at the time of drug starting.
Because UIScrollView.Press (false) in UIDragScrollView isn't called at the time of a drug end.
UIScrollView.mPressed won't be false, so you keep clearing UIScrollView.mScroll.

Try simply adding "mPressed = false;" to UIScrollView's OnDisable function.

1. void OnDisable () { list.Remove(this); mPressed = false; }

UIScrollView isn't invalidated in case of Drag&Drop, so it isn't improved by the correction.

The cause is because UIDragScrollView.OnPress (false) isn't called to the time of a mouse release of an item.

Had a look into this.. add this to UIDragScrollView and it fixes the issue:

1.         void OnDisable ()
2.         {
3.                 if (mScroll != null)
4.                 {
5.                         mScroll.Press(false);
6.                         mScroll = null;
7.                 }
8.         }
