03/04/2023, 10:54 AMis there any actual difference between virtual and non virtual lists? - a
ambitious-knife-25690
03/04/2023, 10:54 AMmaybe the difference will tell me where to look - b

03/04/2023, 10:54 AMhuge differences - a

03/04/2023, 10:55 AMahh 😅 - b

03/04/2023, 10:56 AMa non virtual (normal) list will create vbox with all the items in it... so if you have 100 items, there will be 100 item renderers in the vbox and the whole vbox will clip... a virtual list only has the number of item renderers that can be shown ( +1 ) and it recycles them and scrolls the data - b

03/04/2023, 10:56 AMthats why in a virtual listview you can have millions of items - with little to no perf impact - b

03/04/2023, 10:56 AMbut you shouldnt need to do anything specific - a
ambitious-knife-25690
03/04/2023, 10:57 AMokay, so logically speaking a virtual will be added to the list later and a non virtual would be 'queued up' - a
ambitious-knife-25690
03/04/2023, 10:57 AMmaybe it's the timing of when things are added that affects the depth - a
ambitious-knife-25690
03/04/2023, 10:58 AMbut the queued up items in the virtual list work 🤔 - b
bright-gpu-74537
03/04/2023, 10:59 AMnot really, its just how the item renderers are used essentially - from your perspective there shouldnt be any difference, but again, if your backend is fundamentally misbehaving who knows what effects it has... - b
bright-gpu-74537
03/04/2023, 10:59 AMi think (and its a guess), virtual uses more addAt, removeAt and non-virtual uses more add / remove... but i could be wrong about that - a
ambitious-knife-25690
03/04/2023, 11:00 AMOoo that gives me something to test - b

03/04/2023, 11:04 AMNot following closely, but if you animate on mouse down then you need to unregister events while animating. Otherwise it could re-report the mouse down. Probably best to un listen to all mouse events while animating. - o

03/04/2023, 11:05 AMby moving under the mouse it maybe possible for an event to be retriggered - o

03/04/2023, 11:06 AMdepending on the internals of the backend? - o

03/04/2023, 11:07 AMFor a toggle you certainly don't want the animating object to be active to mouse during transition? - a
ambitious-knife-25690
03/04/2023, 11:08 AMhehehehe, this shows something very interesting happening 😄 - o
orange-van-60470
03/04/2023, 11:08 AMif under the mouse - b
bright-gpu-74537
03/04/2023, 11:08 AMits got nothing to do with the animation, we've established that, and more likely something fundamental wrong in the backend - a

03/04/2023, 11:09 AMtop 1 works fine - a
ambitious-knife-25690
03/04/2023, 11:09 AMbottom one fails - b
bright-gpu-74537
03/04/2023, 11:09 AMfigures... as i mentioned, try to fix the base issues then things should "just work" - o
orange-van-60470
03/04/2023, 11:09 AMthis is the problem of the animation target not finishing before next target - o
orange-van-60470
03/04/2023, 11:10 AMyou need to consider disable while moving or use virtual values - b
bright-gpu-74537
03/04/2023, 11:10 AMits not... and i dont know why you are asserting that with such authority when you have no idea what you are talking about... 🤦♂️ - b
bright-gpu-74537
03/04/2023, 11:11 AMthe issue, as stated, is within the backend and it not doing something correctly... nothing to do with animation - a
ambitious-knife-25690
03/04/2023, 11:11 AMi guess this shows my addcomponent`at` and removecomponent`at` implementation not workincg - a
