ListView not supporting fast clicks?

[StefanWo]

After i updated from 2021 to 2022.2.14 it seems the change event of the Listviews.

My guess is, that it only supports single clicks, doubleclicks will be ignored. When moving fast with the mouse over the list and clicking fast, it just selects the first element. Here a Gif, showing the strange behavior.

Not sure what you mean but you can check double clicks like so:

        private void selectGame(ClickEvent evt)
        {
           /* ... */
            if (evt.clickCount >= 2)
            {
                GamesListController.Instance.OpenGame(game);
            }
        }

Not sure what you mean, i’m talking about the ListView element of the UI Toolkit. Sure i can add own handlers to fix this bug by myself.
I have the feeling that its a deeper problem in UI Toolkit, that the clickcount is calculated wrong. I guess it should reset when i over over another element but it acts like a global clickcounter. So even when i click once somewhere else and than to e.g. a button, it’s showing clickCount=2.

Hey there !
I’ve got the same problem here, this has been reported in those two old threads :

ListView.onItemsChosen is called on 3rd click

Hello, Using latest unity 2021.2.0f1 (UI Toolkit, runtime). Noticed strange behaviour on item double click in a ListView. There is no effect if you just double click an item, only on 3rd click it’ll call onItemsChosen. 3rd click can be even done with a delay (like double click, pause, click) Also noticed that MouseDownEvent always returns clickCount = 1 (was returning expected click count before), MouseUpEvent seems to work normally. Please note, I’m using Input Manager (Old). Is it an expec…

ListView does not intercept triple clicks.

I have a listView with both onSelectionChange and onItemsChosen set. void OnSelectionChange(IEnumerable<object> x) { Debug.Log("listView selected: " + listView.selectedIndex); Clicked(items[listView.selectedIndex].id); } listView.onSelectionChange += OnSelectionChange; listView.onItemsChosen += OnSelectionChange; It handles single clicks and double clicks fine, but if I triple-click it passes through to the VisualElecment behind and triggers my MouseDownEven…

It seems that by default the ListView is checking double click without knowing wich item is hovered so it’s skipping all other click when a double click event is fired.

From my test : I’ve got a ListView, with 3 items in it. The only event i’m listening to is the selectionChanged event.
If i click slowly, i can select any item i want. If i click fast between two items, a double click is registered, and i have to wait to do a new selection.

Going to run with a scroll view and buttons instead…
