How to place image in background of widget?

I want to place a pic in widget and some buttons over it. But buttons always go away behind the image.

How to make buttons appear over the pic?

Had to change zOrder.

For those wondering, the ZOrder is only available on objects like a ScaleBox and not an image itself so you have to place your BG image inside of a ScaleBox and then set the Z order of the ScaleBox to 0. Then add another ScaleBox for your text and set its ZOrder to 1 etc.
The ZOrder determines the layer order so to speak.
