Python xlib window

No sanity is needed. But that's not what the article is about. What the article is about is that the C runtime shim that ships with Visual Studio defaults to using the ANSI API calls without supporting UTF-8, goes on to identify this as "almost certainly political, originally motivated by vendor lock-in" which it's transparently notand then talks how Windows makes it impossible to port Unix programs without doing something special.

I half empathize. Microsoft robustly caters to backwards compatibility. This is why the app binaries I wrote for Windows 95 still run on my laptop. There are heavy trade-offs with that approach which in general have been endlessly debated, one of which is definitely how encodings work, but they're trade-offs. Just like how Windows won't allow you to delete or move open files by default, which on the one hand often necessitates rebooting on upgrades, and on the other hand avoids entire classes of security issues that the Unix approach has.

But on the proprietary interface discussion that comes up multiple times in this article? Of course those need APIs different from the Unix-centric C runtime, and it's entirely reasonable that you might need to look at them if you're targeting Windows.

A lot of the article is about string handling, I very much agree with that part of the article, having worked on a lot of legacy code built over decades before the introduction of UTF-8 compatibility. It gets worse with that old code if you try to share modules between windows and Linux applications.

Additional complications come from trying to support TCHAR to allow either type of char for libraries. CountSessine 1 day ago root parent next [—]. If you need to do stuff that's not covered by the standard library, like interfacing with GTK or X11 you are in a world of pain. If you suffer through this, you have an exe that works on your version of Ubuntu, maybe on other versions of Ubuntu or possibly other Debian-based distros.

If you want it to also work on Fedora, it's back to tinkering. Tbh i think the only sane-ish way of building to dockerize your build env with baked-in versions. In contrast, you pick and SDK and compiler version for Windows, and as long as you install those versions, things will work. CountSessine 2 days ago root parent next [—]. Versus no dependency management at all? This reasoning falls apart once you need to use a 3rd party library on Windows.

You can always ship your program with its dependant libraries the way you always have to on Windows. Linux gives you options. Yeah, you're right, but you probably need a lot less stuff that's not in the SDK.

My go to solution for including dependencies, is just checking in all the dependency. And I don't particularly love the idea of using root access to install packages to just build some random person's project. Indeed, and the fact that it's platform-specific in the first place certainly doesn't help! When I last wrote one I was very new to it and rpm. It looks like rpm. I had a bunch of special requirements for the lib I was making and not having docs for the format, especially all the funny macros, was pretty frustrating.

X11 as a protocol has always been backwards compatible and Xlib on Linux pretty much never broke the ABI since the 90s.Sorry, something went wrong. I actually posted this as the "full version" of a code snippet I put up on StackOverflow, but you can consider it MIT-licensed if you'd like something more concrete. Regardless of which terms you use it under, I'd appreciate a shout-out. Nothing fancy Is this code part of any maintained open-source repository right now?


It's not so much that "getting the active window requires so much" as "if you need to do something GTK and Qt don't provide a wrapper for, you have to speak raw Xlib Code written against the raw Win32 API is at least as verbose and ugly.

Personally, I think it's worse. This works great except it doesn't seem to notice when the active window ID changes if the new window has the same title. Is there a way to get it do that as well? To disable it, replace line Thanks a bunch! Great script! The biggest issue for me was having two or more terminals cd'ed to the same directory. They could all be running different programs, but x11 reports them as all having the same title. Also, two or more browser instances showing the same page would do the same thing.

I am wanting to run your script when I start X, but I found that if there are no windows open when your script is run, it exits. Is there a way to have it run and stay open even if there are no windows currently open.

The script continues to run if I close all the open windows, so it seems to only be sensitive to no windows open on launch. I've rewritten the code to account for that, added some MyPy type annotations, and fixed a couple of oversights revealed by that as well as a potential bug that showed up during testing. Let me know if you have any further problems.

Does anyone know how to turn code above into rust code? Find them. ShayBox The problem is that, when you start to think about how to integrate it into programs which may already have an Xlib connection for other purposes, it's not as simple to offer it up structured that way. Unnecessarily pushing a program to open more X sockets is a code smell. What you want to do is check xprop 's output to identify a property you can listen for changes to.Amazing Games Made Here.

Nite Fighter. Published by Activision, Inc. Pygame Shaders Library.This documentation is still a work in progress. Although Python 2 is no longer actively maintained, there are some packages that still depend on it. First create a small Python script called hello. So we pass it our method and it enumerates the windows, passing a handle of each window plus our Python list to our function. This is the home of Pygments.

Roblox bot Roblox bot PyGetWindow. This is still fast in Python terms, but it just cannot match the speed of the low-level NumPy method.

Go to the directory of. The name of the module is incorrect. We will first cover the spack install command, focusing on the power of the spec syntax and the flexibility it gives to users. The apache web server is listed as "httpd" and the Linux kernel is listed as "linux".

Python ctypes. It usually provides features such as build automation, code linting, testing and debugging. At this point, we need to add a little code to login. By Al Sweigart. Finally, it shows how to compile and link extension modules so that they can be loaded dynamically at run time into the interpreter, if the underlying operating system supports this feature. See the Installation page for The official dedicated python forum.I can do s. Afaik there are direct python to Xlib bindings.

In Xlib, the XQueryTree function can be used to traverse the window hierarchy. It starts from the root window or a specific window and gives you a list of window ids of the windows child windows.

XGetClassHint allows you to receive the class name and class for a specific window id. That's the c way to do it. If you have a direct binding for python, you'll likely have to do it the same way. There may be other libs that provide Xlib bindings in a more pythonic fashion. This is python-xlib in community. I have been using it in fpdb and found it to be a pain in the butt. It has been causing some crashes on various systems. It also doesn't handle things like non-ascii chars in window titles.

I have gone back to using xwininfo to get the same information. This is actually sufficiently more complex that it would seem at first. Iterating over the QueryList of the root window isn't quite enoughsince you're going to get a lot more results than you otherwise would. There are many windows that usually make up each client. There are two approaches here.

This is an EWMH standard. The property is maintained by the window manager and contains a list of all window IDs that the window manager is currently "managing.

While you can use python-xlib and in my experience, it is perfectly suitableyou might also try xpyb, which is the Python version of XCB. The following should do the job you're looking for:.

Finally, if you're going to do any more heavy lifting, may I suggest you check out my xpyb-util git repository? The above could be condensed into this with xpyb-util:.

Education is favorable to liberty. Freedom can exist only in a society of knowledge.

Last edited by hbekel The following should do the job you're looking for: import struct import xcb, xcb.The Python X Library requires Python 2.

It has been tested to various extents with Python 2. It is written entirely in Python, in contrast to earlier X libraries for Python the ancient X extension and the newer plxlib which were interfaces to the C Xlib.

This is possible to do since X client programs communicate with the X server via the X protocol. The C Xlib is merely an interface to this protocol, providing functions suitable for a C environment.

Integration: The library can make use of the wonderful object system in Python, providing an easy-to-use class hierarchy. Portability: The library will be usable on almost any computer which have Python installed.

Maintainability: It is much easier to develop and debug native Python modules than modules written in C. The low-level protocol is complete, implementing client-side X11R6.

The high-level object oriented interface is also fully functional. It is possible to write client applications with the library. There are most likely still bugs, but the library is at least stable enough to run PLWM.

A continuously bigger part of the library is covered by regression tests, improving stability. The documentation is still quite rudimentary, but should be of some help for people programming with the Xlib. X beginners should first find some general texts on X. Installation The Python Xlib uses the standard setuptools package, to install run this command: :: python setup.

Alternatively, you can run programs from the distribution directory, or change the module path in programs. There's a simple example program, implemented twice using both the high-level interface and the low-level protocol.

There are three advantages of implementing a pure Python library: Integration: The library can make use of the wonderful object system in Python, providing an easy-to-use class hierarchy. Documentation The reference manual is not finished by far, but is probably still useful.

Project status The low-level protocol is complete, implementing client-side X11R6.The intent of this window manager project is largely to expand my understanding of the X11 libraries via Python. However, it should be good for some basic use cases such as lightweight virtual machines or a Raspberry Pi. It is not recommended to run BiscuitWM on a production machine without using Xephyr to run an embedded X session!

In terms of hardware requirements, as long as it could run Python and your applications probably a Raspberry Pi is more than good enough. As for the operating system, perhaps Linux specifically any Debian-based distribution should suffice.

After install these packages, use pip to install the relevant Python libraries. Use git to clone the project's GitHub repository onto your system, or download the ZIP archive from GitHub which then has the extra step of extracting the archive.

Open a terminal in the project directory, and run the install. This will copy the source file, a shell script that runs the source file via Python, and the session files to the system directories. Hovering your cursor over a window will automatically raise it and make it the window with input focus.

Some things that could be customised include window placement behaviour, the deskbar and the clockrounded desktop corners, and window borders. Future iterations to BiscuitWM will add titlebars to windows, and may turn hover-to-raise behaviour into an optional feature.
