Hi Brian (hope you are still there), the code in 31_8.tcl is not
complete so I didn't bother looking into it.
The tkdraw.py is not really correct, here is a cleaned up version that
works:
from Tkinter import Tk, Canvas, LAST, ROUND
def StrokeBegin(event):
print "clicked at", event.x, event.y
del stroke[:]
tuple = (event.x, event.y)
stroke.append(tuple)
def Stroke(event):
tuple = (event.x, event.y)
coords = stroke[len(stroke)-1] + tuple
stroke.append(tuple)
canvas.create_line(coords, tag='segments')
def StrokeEnd(event):
canvas.delete('segments')
if len(stroke) < 2:
# Just a click happened
return
canvas.create_line(stroke, tag='line', arrow=LAST,
joinstyle=ROUND, smooth=1)
stroke = []
root = Tk()
canvas = Canvas(root, height=400, width=500)
canvas.bind("<Button-1>", StrokeBegin)
canvas.bind("<B1-Motion>", Stroke)
canvas.bind("<ButtonRelease-1>", StrokeEnd)
canvas.pack()
root.mainloop()
