You will need to create a custom widget for that with your own custom OnFill function.

I don't know how to make custom widget or how to use OnFill function.
Would you please explain it for me?
Thanks in advance :)

Just have a look at how existing widgets are made. For example look at UITexture. It inherits from UIBasicSprite, overwriting its OnFill function which is what does the drawing. In UITexture's case it simply uses the Fill function inside Basic Sprite after figuring out the inner and outer rectangles of the texture (used for slicing). In its heart the OnFill function is simply about filling the geometry buffers. You can replace the whole thing with the UIBasicSprite's SimpleFill function for example -- it can't get any easier than that.
