I tried to test the Override Functions inside Widget Blueprint
With OnMouseButtonDown and with OnMouseMove, but none of the tests was able to do something…
You most likely need something to test the mouse interaction against.
If you have a clean widget with just a canvas, its Visibility is set to Self Hit Test Invisible. No mouse input will be detected in this case.
Add a Visible widget element to your canvas or change its visibility to Visible.
You just saved my day!
However, it seems that is work only on the part where is something on the screen.
I tried also with Set Visibility but seems that is working only when there is a mouse cursor on the screen.
But I’m still glad that is finally working,
Thank you!!!
