How to draw a 2d box

ROOT
1

I read in the user guide (p.107):

b = new TBox(0.2,0.2,0.8,0.3)
b->Draw()

nothing apparently happens. Why? I need to draw some rectangcles in my canvas with different colors.

Hi,

The box is there but has the same color as the canvas (by default). If you add b->SetFillColor(5); before b->Draw(); you will see it. I will change the example in the User’s Guide to avoid this confusion.
