Drag & Drop does not work with Buttons in 4.17

Development Programming & Scripting UI

Hi there,

I have found an issue with 4.17.1

If you have a drag and drop widget, with a button, the drag is not registered. When I disable the button, the drag works again, but it greys out the contents inside the button.

It is relatively easy to reproduce, if you follow any of Unreal Engine’s Drag & Drop tutorials most of them use buttons inside the drag-able widget.

Let me know if you need any more information.

Cheers

I too am experiencing this issue. The only work around I have found is to use the middle mouse button or right mouse button for the time being. I’m am hoping epic fix this soon.

Hey guys…yeah this was driving me insane until I finally stumbled across this. I have had to re-write the Programming Unit and used UE4.17 for the college I work for and thanks to the above from thejhNZ I flicked the switch to middle mouse button and bam…works…so I will just note that for the students for now!!! Let’s hope it gets fixed in the near future. So I do reccommend anyone else having this issue to do the same until it’s investigated and fixed.

Hi,

It’s best if you educate them that using a button for drag & drop is not how epic wants it to be done any more. You can see my thread here, where a Epic Staff replied about this : Please include drag & drop fix in 4.17.2 - Feedback for Unreal Engine team - Unreal Engine Forums

I also include a work around - which I have used & tested.

Cheers
