Dear All,

I am totally new to Python, however had some experience with Tcl/Tk.
Currently I am doing a project that will need Python/Tk as well
as VTK(Visualization Toolkit) for image processing and visualization.

Have anyone had any experience in this that can give me some suggestions
or references? And I also wonder how Tk is working with Python in
the process of constructing GUI, is it like the way that with Tcl?

Any help will be greatly appreicated. Thanks.

Yours,
Casper

I never used VTK, so I cannot help you for this part. As for the GUI
construction process in Python/Tkinter, the only difference with tcl/tk is the
syntax. For example, instead of doing in tcl:

frame .frm -width 500 -height 200 -bd 3 -fg red
pack .frame -side top

in Python, you'll do:

## Import the Tkinter module
from Tkinter import *
## Initialize Tkinter/tk
root = Tk()
## The next two lines are the equivalent of the two tcl lines above
frm = Frame(root, width=500, height=200, bd=3, fg='red')
frm.pack(side=TOP)

So you see, it's quite straightforward. The concepts, widgets, operations,
options, ... are exactly identical in Python/Tkinter and tcl/tk. In fact, the
Tkinter module actually creates a tcl interpreter in the background and converts
all calls to Tkinter objects to tcl commands. So once you've understood how to
convert tcl syntax to Python/Tkinter syntax, you can even use the tcl/tk manual
pages as a reference.

Have a look at the MayaVi project, which uses Tkinter and VTK for data
visualization. You should be able to get some ideas from that.
