Embedding Matplotlib in wxpython wx.Panel problem
Hi,
I'm trying to create a small GUI program where I can do plots using
Matplotlib. I've been trying to borrow code from the examples at the
matplotlib website, but I can't get it to work.
I want to be able to create a wx.Panel that contains an axis for
plotting. Around it i want other panels containing various settings,
buttons etc. to control the plot. So far I can't even get the program
to actually show a plot in a panel.
Does anyone here have experience in making a wxpython GUI with
matplotlib?
Any help would be appreciated!
Thanks,
Soren
My code shows a frame, and I'm trying to set up two panels.. one with
a plot and one with a button.. The plotpanel is just a little square

How do I parse a string to a tuple??
Hi! I have a string that contains some text and newline characters. I want to parse the string so that the string just before a newline character goes in as an element in the tuple. ex: "text1 \n text2 \n text3 \n text4" --> (text1, text2, text3, text4) Is there an easy way to do this?

Python crash after using weave inline
Hi,
I have a strange and very annoying problem when using weave in scipy..
when I run the code below.. the first time it needs to compile.. it
says and then python.exe crashes! and no result is shown..
the second time i run it, it does not compile but gives the completely
wrong answer.. prints a matrix of all zeros except for point 1,1 in
the matrix which seems to have some random high number like
-5.39403959e+08. !!??
Basicly I run through a 10 by 10 matrix do some calculations with
respect to some center values x_c and y_c and insert the result into
the empty numpy matrix array "res".
Any help is appreciated!

Parallel port control with USB->Parallel converter
Hi, I want to control some motors using the parallel port.. however, my laptop does not have any parallel ports (very few do). What I do have is a USB->Parallel converter... I thought about using PyParallel, but the USB->Parallel converterdoesn't actually map to the LPT port .. and PyParallel only looks for LPT ports? Has anyone tried doing this? What are my options for controlling parallel connections on a laptop with no parallel port? I also thought about controlling the USB natively.. but since I dont have any instructions on how to do this with my Velleman USB->Parallel port converter... i guess I would be totally blind. Any help would be appreciated! Soren -- http://mail.python.org/mailman/listinfo/python-list
Re: Parallel port control with USB->Parallel converter
Hey Diez, thanks for your answer! > You could try and see how far you get with pyusb, the wrapping for libusb. > However, any decent usb2-adapter should register itself as device > of the mapped kind. For example, usb2serial-converters appear as > COMx:-ports. That was my thought too, and that's why I bought one (actually I bought two), but it turns out that people only use these to interface with old printers.. and so the converter is listed as a USB printer port, and does not directly map itself to the LPT port.. Of course, there must be some way of controlling the USB2PAR the way I want, but without something like PyParallel or an API for this converter.. im pretty much in the blind.. :/ > Apart from that, you might consider using products like atmel's USB-Key or > similar to attach a microcontroller to the USB-port that then will use it's > own ports to control the motors. I thought about it.. this would be my last option however... mostly because it would take too much time to get acquainted with it. I need the thing running before the beginning of March among other things.. :) I do have a LabJack USB DAQ, which is really nice... but unfortunately it's too slow for running 5+ motors in parallel by sending pulses. I also thought about extending the labjack with faster pulse generators that could be triggered from the labjack. Using the parallel port or USB2PARALLEL on the pc would just be so much simpler, cheaper and faster... So if anyone know how to hack an USB-Parallel converter to let me send bytes to it.. I'm all ears!! :) Soren -- http://mail.python.org/mailman/listinfo/python-list
indexing arrays in extensions created with ext_tools (scipy.weave)

Wxpython. Is it possible to change layout in a running application? Selfmade listbox
Hi, Id like to make my own special listbox.. I want to able (at the push of a button) to add another item to my special listbox... each item is a panel with a label, some buttons and maybe a text control. I've tried adding a new panel object with the stuff i want to the sizer i'm using for my listbox (which is a panel which can contain other panels)... and then run update() and refresh() on everything... But it doesn't work.. i see a panel appearing, but it's just a small square in the corner of my "listbox" panel, and it only works the first time... nothing new appears when I push the button again. Is it at all possible to do this? Has anyone created something similar? Does anyone know what i'm doing wrong? Thanks, Soren -- http://mail.python.org/mailman/listinfo/python-list

SWIG Python undefined reference
Hi,
I went through the SWIG tutorial for the example named "simple".
I managed to get to the first step, creating example_wrap.c using
swig, and doing:
"gcc -fpic -c example_wrap.c -IC:\python24\include " to create
example_wrap.o
But when I needed to compile the library file using:
"gcc -shared example_wrap.o -o examplemodule.so" I received a lot of
undefined reference compiler errors like:
example_wrap.o(.text+0x35a5):example_wrap.c: undefined reference to
`_imp__PyErr
_SetString'
there are many other similar errors all prefaced with _imp__Py, so I
