On the last line you create a lambda, an anonymous function, which you pass
as the command callback for the button. Of course, no code inside the
lambda is actually executed at this point. It is only after the entire for
loop has completed, later when the user sees

This indicates that it expects the "callback" to be a Python object.
Check the C-API specification. It should tell you which parameters

Hi everyone,
just like the title says I'm searching for a mechanism which allows to call a
callback function from a thread, being the callback executed in the parent
thread (it can also be the main thread). I'm basically looking for something
like the CallAfter method of the wx or
e to be called every time the slider is moved. This
procedure will be passed one argument, the new scale value.
If the slider is moved rapidly, you may not get a callback for
every possible position, but you'll certainly get a callback when
it settles

If I had seen this post I might not have even spent time on Cython. (For some

This line should be:

Without the byref(...), it will try

Hi,
I am wondering if anyone here might be able to suggest if there is a way of
switching over from python execution into debug mode of an IDE, from python
code that is executed as a callback from a C++ DLL?
Thanks

Hi I am opening a shared library which has defined the following
callback prototype:
extern void DebugMessage(int level, const char *message, ...);
My implementation in Python looks like this:
DEBUGFUNC = ctypes.CFUNCTYPE(None, ctypes.c_int, ctypes.POINTER(ctypes.c_char))

Hello all,
I wonder if someone could explain some of the following.
(Python 3.2)
I have a class which has a method called 'callback()'.
An instance of this class calls a C extension which
then calls back into Python.
In all cases below, two arguments are passed to the C
code and
Hi,
I'm trying to write a COM client to a COM server which controls a power
meter. The COM server fires events that should be handled by the
client. The docs state that I have to supply a class which implements
the IFM2DeviceEvents interface. I need some instructions on how to
translate the VB sam

print proc.stdout.read()

Here is a solution using plac (http://pypi.python.org/pypi/plac) and
not OptionParse, in the case
the Linux underlying command is grep:
import subprocess
import plac
@plac.annotations(help=('show help', 'flag', 'h'))
def main(help):
if help:
script_usage = plac.parser_from(main).forma
Hi,
I want to display help message of python script and then display help
message from the binary file (which also supports -h option):
Assumptions:
1) 'mybinary' - is linux executable file which supports '-h' and on '-
h' option it displays the help message
2) myscript.py - when passing '-h' opt
