Error in trying to locate bitmaps files

[Robert Cragie]

The syntax of 'bitmap=@<filename>' goes straight to Tk, therefore appending
to sys.path won't make any difference . A snippet from the Tk help file says
this:

<snippet>
@fileName

FileName must be the name of a file containing a bitmap description in the
standard X11 or X10 format
</snippet>

Unfortunately, that doesn't help me much either; maybe some other kind soul
can help.

If you specify the full path for the file it works, e.g. on my machine

Label(f2,bitmap='@C:\\Program
Files\\Python\\src\\Grayson\\examples\\chapter04\\bitmaps\\woman',text="My
second label in tk",relief=RAISED).pack(side=LEFT, padx=5)

works OK. That's why the example works - the pathname is valid relative to
where the application is run.

A word of warning - if you're trying to enter things interactively in IDLE,
you can get unstuck with Tkinter apps. as IDLE is written using Tkinter as
well. The most notable thing is NOT to call the mainloop() method in IDLE.
Also, I have found some problems with some of the examples if you are using
Python Megawidgets 0.8.3 - there are some subtle differences between 0.8 and
0.8.3.
