Hey,
I have used two great models - Tkinter and Gnuplot.py - for a while. I
can display an image on a Canvas widget using Tkinter and I can also
generate a gnuplot from Python on the fly in a separate window. Does
anyone know how to display such a gnuplot on the Canvas widget with an
image in it? Thanks.

From my experience, the Gnuplot module isn't designed to be used in
"headless" mode -- it can save to the usual formats, but you have to
render everything in an x11 window interactively first.
It might not be hard to modify this, though.

Thanks, Jonathan. Can you please give a little more information here?

That's not correct. I have tons of Gnuplot.py based scripts which write
directly to EPS output, without ever opening a gui window. Note that Gnuplot
still tries to initialize the X11 terminal at startup, so they would require
modifications to run over ssh without X forwarding.
The default plot() command in Gnuplot.py doesn't make it too convenient to do
this, but it's possible. The Gnuplot support in ipython
( http://ipython.scipy.org) extends the syntax of the plot() command to make
it trivial to render to EPS without a terminal. It shouldn't be hard to
modify this to render to other formats, while avoiding opening an X11 window.
Best,

Hi,
I'm trying to put an Tkinter.Entry of fixed size onto a specific location
on a canvas using the place manager. The idea is that one can double-click
a rectangle object on a canvas to get an entry field of the same size
as the rectangle placed exactly over the rectangle thus creating
the effect that the rectangle has entered "input mode". When clicking
return in the entry field, the value is fed back to a text object within

Hello,
I have a Canvas-Widget and will use as a "array of pixel". At Positon

Hi,
I do a "perso"widget where have two scrolls (one vertical, one
horizontal) for a canvas.
When, the first time, I added widget in the canvas, the scroll self-ajust
and when I move scrollbar, the surface's canvas "moved". But when I deleted
(.destroy) this first widgets and that a added other widget, the scrollBar
become disabled (ajust for no scroll on the canvas). What/where is the
problem?

Hello. When I tried to make Tkinter canvas widget respond to
MouseWheel event on Windows XP, I failed. The canvas just doesn't
receive MouseWheel event. I used bind_all to find out which widget

gets it. This is really annoying. I wonder if this problem exists on
other platform. I googled, but found no appliable solution, so I wrote
