As you may know, we have a prototype of a PDF backend, though it is
missing many features.

At some point, we upgraded our tk filesave dialog to use the more
modern one.  We could always revert to the old one, which would
likely fix this but let's give it a day and see if we can't have the
best of both worlds.  Hopefully, the effbot will pick up on my c.l.py
post...

The weird thing is that this used to work fine in the past.
At least, I am pretty sure it did.
Then again, I am watching the Worlcup final at this time.
So a significant part of my brain is doing something else,

Interesting.  the tk ask file dialog seems to be triggering a destgroy
event on the main window, which removes it from mpl figure
management.  Here is a minimal Tk script which exposes the problem.
When you press the mouse button, you get a file dialog that when you
close it triggers a destroy event and calls the callback function

I don't know if this is a tk bug or if we are misusing the Tk code.
Tk experts?


I'll post on python-list.

import Tkinter as Tk
from tkFileDialog import asksaveasfilename

def button(event):
    fname = asksaveasfilename(
        title='Save the figure'
        )


            

window = Tk.Tk()
frame = Tk.Frame(window, width=500,height=500)
frame.bind('<Button-1>', button)
frame.pack()


def callback(*args):
    print 'called callback'
window.bind("<Destroy>", callback)

window.mainloop()

Confirmed: bug is still there, with current SVN mpl under python2.4.

Cheers,

John was asking whether there was something left to be fixed befor 0.88.
In 0.87.3, there is still a bug left that has been reported several times I
think.

In interactive mode on TkAgg, after solving by clicking on the 'save' button
in toolbar2,
mpl loses its knowledge of the figure. Any plotting statement given after
that
creates a new figure, rather than add to the existing one. I wish I knew how
to fix this.
I am (still, but not much longer) running Python 2.3, but I think Fernando
reported
the bug in Python 2.4 as well.

Thanks,

Mark
