At present, the focus of the button and the normal use the same image. This makes it impossible to confirm whether the button is currently focused when the keyboard or handle is operated. If I use a dynamic material, I must set the whole style in the blueprint instead of assigning the dynamic material ref to the normal slate brush. Although I can set the whole style, it is too cumbersome and cumbersome for a large number of umgs, and it is not easy to edit and modify. It is hoped that in subsequent versions, the focus image of buttons or other widgets can be set separately, or at least distinguished from normal. For example, the focus and of buttons can adopt the same pattern as hovering.
