[UMG] Position widget next to another one?

Development Programming & Scripting Blueprint
1

My hierarchy

  • Canvas_A
    • Canvas_B
      • MyWidget A
      • MyWidget B
      • MyWidget C
      • … many more MyWidget … Created at runtime
    • TooltipWidget
    • PlayerCursorWidget

When my player cursor widget is hovering over any of MyWidget widgets, I’d like to position the tooltip near it.
I managed to check when the player cursor position is over any MyWidget, but how do I position TooltipWidget near it?
