Getting an image from a file on windows
Hello, I have been working on a function that gets a bitmap of the thumbnail for a file. I have had problems getting a large image (256x256) and I was wondering if someone could help me on one object initialization that is driving me nuts. I have code here: https://gist.github.com/IronManMark20/a83fe7ff7ea9b40c09af I need to initialize a *void pointer for the third argument for SHGetImageList (ref https://msdn.microsoft.com/en-us/library/bb762185). What should the initialization look like (please give me example code, not just Oh it should be a ctypes.c_void_p). Thanks!!! -- https://mail.python.org/mailman/listinfo/python-list

Now I get to figure out how to get the image. -- https://mail.python.org/mailman/listinfo/python-list

Could you suggest how I could get an hIcon from the newly drawn image? I have been trying, but I haven't found anything. -- https://mail.python.org/mailman/listinfo/python-list
Re: OpenCV with Python (cv or cv2)

I installed version 2.4.9 (http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.9/opencv-2.4.9.zip/) in debian Squeeze running Python 2.6.6. Using the tutorial: http://indranilsinharoy.com/2012/11/01/installing-opencv-on-linux/ (I tried to install versions 2.4.11 and 2.4.10 (in Squeeze with python 2.2.6) but I couldn't.) I lost some time trying to load the module cv2: Import cv2.cv the cv Traceback (most recent call last): File stdin, line 1, in module ImportError: No module named cv2.cv After a while I realized I could use the cv module. (import cv) But still I do not understand the differences between the modules cv and cv2. Do you suggest any good tutorial about the differences between cv and cv2? I will have to make many changes in python programs using cv to reuse the code later with cv2? Thanks, Markos To actually answer your questions, cv2 is the newest and best opencv binding. It uses numpy arrays, instead of what cv uses. This means it is much easier to deal with.

Re: Best GUI for Python
But just curious: what is the reason you use five different kinds of GUI? It seems like it makes think difficult for you. I mean the question as enlightenment for myself. A good question :). Most of this comes from the openness to create binding for many projects. Tkinter is a binding of Tk. pyGTK is a binding of GTK, which is written in c++, the same is true of PyQt/PySide, which binds Qt. wxPython binds wxWidgets. I find the variation good, because it means there are more choices. I use PyQt, because I wanted very cross platform code, other choose pyGTK because they want to closely integrate with the GTK environment. Your choice of GUI library depends on what you are targeting. -- https://mail.python.org/mailman/listinfo/python-list
Hooked, a pure Python Windows Hotkey module
Announcing Hooked Hooked is a pure python hotkey module. There are some great options such as pyHook, and pyhk, but I wanted a pure Python version so all Python implementations could use hotkeys. Now, an example! def foo(): print I was triggered by Ctrl+B! from hooked import hook hk=hook() #make an instance of hooked hk.Hotkey([LCtrl,B],foo) #the left ctrl+b causes foo to trigger hk.listen() #start listening for the hotkey I just made this yesterday, so more updates over the next few days. Features: * It should support all keyboard keys * It should allow for an unlimited number of hotkeys to be registered. * It is pure Python, which means you can go and edit things easily. * It supports all versions of Windows since 2000. * It _only_ uses the standard library. No need for pywin32. Hooked is licensed under the GPL v2. The source is here:https://github.com/IronManMark20/hooked Thoughts? Suggestions? Requests? etc? -- https://mail.python.org/mailman/listinfo/python-list
ctypes: using .value or .value() doesn't work for c_long
I am using ctypes to call a few windll funcions. One of them returns a c_long object. I want to know what number the function returns. Problem is, when I try foo.value , it gives me this: AttributeError: LP_c_long object has no attribute value. Any idea of what could cause this? -- https://mail.python.org/mailman/listinfo/python-list
