Detailed Description

This ROOT 7 example demonstrates how to create a ROOT 7 canvas (RCanvas) and draw ROOT 7 boxes in it (RBox).

It generates a set of boxes using the "normal" coordinates' system. Run macro with python3 -i box.py command to get interactive canvas

 
import ROOT
from ROOT.Experimental import RCanvas, RBox, RPadPos, RColor, RAttrFill, RAttrLine
 
# Create a canvas to be displayed.
canvas = RCanvas.Create("RBox drawing")
 
box1 = canvas.Draw[RBox](RPadPos(0.1, 0.1), RPadPos(0.3, 0.6))
box1.border.color = RColor.kBlue
box1.border.width = 5
box1.fill.color = RColor(0, 255, 0, 127) # 50% opaque
box1.fill.style = RAttrFill.kSolid
 
box2 = canvas.Draw[RBox](RPadPos(0.4, 0.2), RPadPos(0.6, 0.7))
box2.border.color = RColor.kRed
box2.border.width = 10
box2.border.style = RAttrLine.kDashed
box2.fill.color = RColor(0, 0, 255, 179) # 70% opaque
box2.fill.style = RAttrFill.kSolid
 
box3 = canvas.Draw[RBox](RPadPos(0.7, 0.4), RPadPos(0.9, 0.6))
box3.border.width = 3
box3.fill.color = RColor.kBlue
box3.fill.style = RAttrFill.kSolid
 
box4 = canvas.Draw[RBox](RPadPos(0.7, 0.7), RPadPos(0.9, 0.9))
box4.border.width = 4
 
box5 = canvas.Draw[RBox](RPadPos(0.7, 0.1), RPadPos(0.9, 0.3))
box5.border.rx = 10
box5.border.ry = 10
box5.border.width = 2
 
canvas.Show()
