Hello,

I am having the same problem trying to get Pmw.blt to work.  The all.py
demo works for the Pmw part, but gives me the "BLT Package not installed"
message when I tried to use Blt.Graph.

My application that I wrote in Python 1.6 on linux gives me the
following:

Traceback (most recent call last):
  File "polar_ed.py", line 332, in ?
    tl.append(editor(root))
  File "polar_ed.py", line 79, in __init__
    self.grf= scoop.polgrf(mainpane.pane('plot'))
  File "scoop.py", line 394, in polgrf
    graph=Pmw.Blt.Graph(parent)
  File "d:\program files\python20\Pmw\Pmw_0_8_4\lib\PmwBlt.py", line 260,
in __init__
    Tkinter.Widget.__init__(self, master, _graphCommand, cnf, kw)
  File "d:\program files\python20\lib\lib-tk\Tkinter.py", line 1758, in
__init__

    self.tk.call(
TclError: invalid command name "::blt::graph"


Has anyone provided the answer to these problems yet?

Thanks in advance,

Chris
