Re: Replacement for pygtk?

Essentially, yes. Although pygobject does not use a tool like swig to generate static wrappers. Rather it uses the GTK introspection API to ask gobject's for their methods and attributes, and then marshalls and calls them at runtime. So you can use pygobject with any GObject-based binary library, not just GTK+. Hope that makes sense. AFAIK, from the source code / include files a .gir file is generated (an xml with all the functions, parameters and info). For example for a simple rectangle_int(x. y. width, height) in cairo you have: From this file a .typelib is generated (a binary, compact representation of the data) and the gi library, using this file and the .dll/.so, creates the correct bindings and function for the language you use (at runtime). Switching from Gtk 3.22 to Gtk 3.24 (or a new 3.26) is only a matter of using the new .typelib/.dll with your version of gi, at least until the gi folks puts the handling of the default values for parameters :) So with the gi package for your python (say 3.5.10) you can use all the Gtk versions, you don't have to recompile for example Gtk 3.24.13 for your python/gi version. To have all the Gtk works with python 3.8 you have only to port / build the gi part (and on windows make some magic to handle the new path handling for the .dll search/load location, but this is another story).

I'm a *fairly* competant Python programmer so, if I have to, I willconsider converting from using the gtk module to using the gi module,are there any good tutorials which might help me down this road?

Re: What's up with Activestate Python?

I guess it's time to switch to Anaconda or ??? I've also used the ActiveState python, expecially for the 2.7.x series, mainly for the oflline docs and the pywin32 libraries. Now the situation is better and with pip is really easy to have an updated python with a lot of libs so there is less need for the ActiveState distribution. My 2 cent.

Re: Python Interpreters In Eclipse
Il 16/11/2018 21:08, Jaxson Baerg ha scritto: Hey, I'm attempting to use python in eclipse and am having trouble with the python interpreter. I am using Eclipse 2018-09 and the latest PyDev and Python 3.7.1. When declaring python-3.7.1.exe as an interpreter it gives an error saying it was unable to get info on the interpreter. It also says a possibility to why could be using an unsupported version. I don't know where to go from here, another piece of information is that I am doing this on a school computer with teacher permission but I don't know if that could be causing an issue or not? Any help would be appreciated, thanks! When setting a pydev interpreter for the standard Pyrthon you should point it to a file named python.exe (I suppose you are on windows) on an installed (or virtualenved) python, so probabably you just have to install it on windows , launching (outside eclipse) the python-3.7.1.exe and following the instruction.

Re: How to decide (and know) which Python GTK version to use?
Il 30/07/2018 19:31, Chris Green ha scritto: OK, thanks, where is its home and full API documentation etc.? -- Chris Green·-- https://mail.python.org/mailman/listinfo/python-list On the first page of the official docs, http://pygobject.readthedocs.io/en/latest/, there are the links to the Python Gtk3 Tutorial, to the Python GI API Reference and all you need to start to work with Pygobject and Gtk3. Just a side note: Gtk3 uses the gobject-introspection (and, for Python, PyGobect) to 'connect' the library to Python (or with Lua or Vala) but the same introspection system is used also for different library, graphical (GStreamer or Goocanvas) or not (Gio).

Re: Suggestion for a "data" object syntax

My editor can toggle tabs highlighting as arrows, and I suppose almost any editor has good support for highlighting of characters by search, etc. For NPP there are even plugins like Regex helper. I like to 'type program.py' and understand what's happening, without have to fire up an editor. While, in C++, the Microsoft IDE (and some other) mark the class members & the parameters so you can easily see what 'counter' is, a lot of guide says that you should call it 'm_counter' if it's a member or 'counter_' if it's a parameter, just in case you don't have your editor (or you're colorblind or you don't like to have the parameters printed with a light grey ...). ... -- https://mail.python.org/mailman/listinfo/python-list
