I am trying to do drag and drop from the widget where is the weapon icon to inventory which is in the left side, by the main widget blueprint how can I know which blueprint is clicked, dragged and dropped?
The dragged blueprint Detects Drag and creates a Drag Operation where you specify the Payload - the widget you’re dragging.
The widget where you deliver the drag overrides onDrop, where you can use the Payload pin to get to the widget you dragged here.
An example:
And a bunch of tutorials that cover this extensively:

If you have a specific question, do tell!
Thanks for your reply the problem that I am facing is that when I have four custom widgets which three of them is inside of the main one so I will call the four custom widgets main,1,2 and 3, what I want to do is make click event from widget 3 and to drop it into widget 1 but drop event only recognizes only inside the 3, so basically clicking an image icon from widget 3 makes a widget to drop that it will be dropped in the 1.
So no dragging operation is involved at all, it’s just about clicking?
Lets see if I got it right:
- this is my
wMain, it has 2 other user widgets inside:

- if the goal is to click on the
wClickMeand move it to the drop zone, I’d call a dispatcher in thewClickMe:
- I’d have an event in the
wDropZone
- and have the main widget bind both widgets:
However, judging by the original image:
It seems that we have slots that will have some content and, once clicked, a slot should move its content to the inventory list? Or are we moving an entire slot? How close am I?
But isn’t this a standard drag & drop I suggested in my very first post?
Widget 3 you will drag and drop it onto Widget 1
DetectDrag + Create OP in 3 and onDrop in 1.
Why wouldn’t it work? What am I missing? My understanding is that we’re simply reparenting one widget from a container to another container using drag & drop.
Thanks! That did the trick.
