- I've used the ListView Widget before, so I thought I remembered how to use it. Lol. Here's the reminder to my future self so that I don't waste another couple of hours in forum posts and google-holes.
This example was created with UE 4.25 but should apply to 4.23 and later (this was when Epic changed the UserObjectListEntry interface).

if only Epic's official documentation would be this useful. Thanks!
I'm shocked by how convoluted this process is. Insane.
really crazy, i just need a simple list😅
Please make more reminders for future you. I hear memory gets increasingly weaker with age.
You know, for a pretty useful widget that I constantly use, I keep having to come back to this video to remember the bizarre setup. Thank you for this
epic games is clearly overcomplicating widgets
Thank you, **THANK YOU**, I wasted so many hours trying to wrap my head around why my ListView-based Inventory wasn't updating properly. I was thinking I had to create Widgets and then Add them to the List - Not that I'd feed the Data to the List and it would make the Widget for me. I was on the verge of madness and about to decide to just learn Slate instead so I wouldn't have to deal with Blueprint abstractions for my UI, but you've singlehandedly saved me from needing to do so.
Have a Subscribe from me, even if you aren't making any tutorial videos.
Now that said, if I ever have to touch Blueprint again in my life it'll be too soon.
FWIW, I actually got mine to work using the method you described by creating a widget and then adding it to the list, after having set that same widget as the base for the list
Would've been nice if you actually gave an example for what list view is actually intended. Which is long lists of thousands, populated through a for loop.
The way they build this is so unintuitive.
You can actually have and store the references of those EntryWidgets but cannot access their variable and so modify the objects. I've no idea if it's made on purpose but it does feel like it's been abandonned half way through.
So the way i bypass this :
Inside the Widget that contain the Listview, i use the ConstructObjectFromClass and using the EntryClass i've made. But the one change that i've made it that inside the EntryWidget i've added an Object Variable that contain every information i need to set the EntryWidget, then same as you i use the EventOnListItemObjectSet promote the output variable to a local variable, cast this to the EntryWidgetClass i've made and then use the Object variable that store all the information FROM that cast.
So inside my Widget that contain the ListView, the construct node (after a refresh) has an input pin and that's how i transfer data through references.
This allow me to dynamicly create new entries and make so that each of my items could be specific to an individual actor, like this : th-cam.com/video/xl6_nJy5gw0/w-d-xo.html
How do i make t possible that i can scroll in the fucking list? i cant get it to work
I think the construction of struct is not essential and quite confusing. we can directly construct subclass of uobject and make the datas as its members.
5:45 ItemData is not showing in the Bind dropdown for me. I'm using UE5.1 if that changes anything (depreciation?)
Ok I figured it. Not shown in the video but need to set the data variable in UData Object to Instance editable and expose on spawn
Holy crap, this is the most convoluted process... I really hope they make something more intuitive for this. Geez.
they never did. crazy
what's a fun and realistic title, +1 and thanks ;)
if scroll does not appear make sure in your main widget where the list view is in, that the list view has "fill" instead of auto + the list view has anchor of full size.
This is like the 6th Listview I implement in my project, and every time I find myself returning to this... That's how unintuitive it is. Thank you for this video.
lemon!!
Pretty much stopped watching at the 'This isn't the right way to do it, but I'm going to do it nonetheless'
Thanks a lot for your help. unreal made it too complicated for such a simple addition or update.
Comment for my future self who has already forgotten.
It's my 2nd time here, and not last I'm sure!
Ducking laughable that this is the process of creating a damn list.
I'm back for the second time in a month because who can remember all this??
Men why they couldnt allow us to make multiple lists within 1 wb.
This is ridiculously complicated.
I don't get why they did it this way, it's so convoluted. I think I might rather create my own setup from scratch, at least then I'd understand how it works and be able to use it.
This is insane...
Thanks for the great tutorial! I only wished you had also shown how to remove the items you set up, as that is the only thing I'm currently missing.
all this for use just show up a list stuff? this sounds scary, im in pain already :V
How would you go about removing an item of the object structure instead of modifying it?
helou :D
Holy fuck this process is atrocious.
レモーンの所で思わ拍手をしてしまったよ(笑)
日本語でこれをView系を説明してくれるものがなかったのでとても分かりやすくありがたいです。
Thanks for taking the time to explain this.
So, what about 4.22?
I love you, thanks
When you said its a bad habit to get player index 0 that was incorrect. If you are using that node you actually only ever really want to get player index 0 unless you are using Split Screen. In multiplayer you would use GetController and cast it to a player controller which would get the Server Player Controller ID.
I'm trying to add a button to the ListViewItem that calls a dispatcher that the owning UtilityWidget can react to. But I can't seem to figure out how to bind or get reference to the ListViewItem's Widget that's created in the list view when adding an item to do this.
Any Suggestions?
gee why did they make it so complicated....I understand list view have to use interfaces, but what a mess of a tutorial
especially at the end
Thanks a lot!
What if the incoming list item is a struct and not an object (When implementing the interface function.)
Annnnnd now _this_ just became _my_ "remind myself how to do it" resource, thanks!!!
Your are the best maaan!! Thanks, you helped me so much!!!1
Thank you so much for this video! I was searching for ages on how to get this implemented!
Very informative!! Thanks. Hope Epic make tutorials like that!
I am running into an issue when my widget is a textbox and I need to update its content, how does it communicate back to the object that stores the data variable?
Really awesome explanation, thank you so much for sharing!
Good stuff, Thank you very much for making this!
thank you very much. its very useful video💗
The key point is the both binding and use class for data reference.
This shit actually helped me so much. Thank you so much
Thank you fellow developer!
God bless this tutorial!
I'm hones. I think you did not really get the point of it. Or maybe its just me. But you keep on creating Objects with data, while thats not really the point. The thing is, take data from Objects You Have. If you would have like an Inventory. Then you would have a huge array with Objects. These are already created and you just plug the array into an for loop which then adds the Items. You make your tutorial way more crazy then it needs to be. But still wp and you have at least the best Tutorial on this i've seen. But i think with you creating this many objects and structs you could mislead others.
For everyone saying this is convoluted...I agree 100%.
But remember the C++ behind it makes perfect sense.
Thank you! It helps a lot for me!
One of the better and well done tutorials I've had the pleasure of going through. This was really helpful! Well done!
much appreciated.
Thank you man!

I think your lemon worked the first go, you were just out of screen space, maybe?
he used set members and not add, which he was setting a null reference
Just a heads up for anyone who comes across this like I did. The video is Obsolete, Sdata is no longer there and can't find any documentation on it so figure out how to adapt.
I think he created SData
SData is a structure created at the very start of the video
lmao
