I knew about wingdings characters, but those green bar are not those from wingdings. The bar may come from such a rectangle box or a line with a thickness. But there is no such rectangle  from wingdings.

You use a Label Object and specify a font that has the bar as a character,  if you can't find a font then you create your own.
 
shonick - If you mean the green/red boxes, I remember them to be labels with a single underscore character, any font.

Yes, that is what I meant. Thanks a lot.
