How to simulate UButton hover

I want to force a button into the “selected” state its in when the mouse is hovering over it. How do i achieve this in C++? (No keyboard focus shortcuts!)

Switch between Hover/Pressed WidgetStyle here.
UButton contains
FButtonStyle WidgetStyle

Simply set WidgetStyle.Normal to whatever style you want.

So if you want to display the hovered state of the button, change it to WidgetStyle.Normal = WidgetStyle.Hovered
