How do I create a box with curved edges using drawing canvas?

Does anyone know how I can draw this box using drawing canvas? Is it possible?

The reason I want to use drawing canvas and not just a sprite is because I'll need to vary the size of the box. I will need the rounded edges to look the same regardless of the size of the box.

Many thanks :)

I'm only trying to draw the orange bit! I don't want to draw the square outside the orange shape.

Doesn't work 9-patch for you?

You can draw two rectangles and four circles.

dop2000 & Asmodean, thanks for the tips.

9 patch is exactly what I was looking for! A basic plugin that I didn't look into when I first got into Construct.

Thanks again :)
