Is there any way to run a Python GTK3 apps on Windows? [Solved]
Is there any way to run a Python GTK3 apps on Windows? [Solved]
Edit: The key was using msys2. After installing Gtk3 and PyGObject following the PyGObject guide for msys2 everything worked fine. Packaging with PyInstaller and nuitka was fine.
I've been developing an image halftoning app for a while using GTK on Linux, thinking GTK is cross platform, and delaying testing it on Windows for quite some time.
Today I decided to finally install Windows 10 (for the first time in more than a decade) on a separate machine and see what works and what does not.
For the past few hours I've been through hell trying to get GTK3 to work. I've followed multiple guides, none of which worked, including wingtk.
Furthermore, even if I successfully compile (or install) GTK, would it be possible to package it all up using something like PyInstaller or nuitka.
At this point I'm thinking of keeping the functions and writing a whole new GUI in Tk for the Windows port, as at least that seems to work.
Am I missing something?
PyQT and WxPython have much better cross platform support. If you plan to rewrite your app anyway, maybe take a look at them to see if they fit your needs.
PyQT / PySide are huge, but they have been very good in my experience coding cross platform desktop programs. macOS, Windows and Linux (even on ARM) are very well supported.
MSYS2 has support for GTK, since I think the windows installer for git (which uses MSYS2) would include GUI tools built with GTK
wingtk should work, though it's been a few years since I tried it. What happened?
Have you looked into using pygame? Not sure how much your app is dependent on gtk3 vs. doing something graphical that can be generic.
Yes, a while ago, at the beginning of the project, and eventually decided against it. GTK, despite it's terrible documentation for python was just a more robust desktop app framework.
I quite heavily rely on sliders, dropdown lists and a file browser and while it's possible to do that in pygame, it's just too clunky.
Am I missing something?
It's impossible to tell without knowing what specific aspect had failed.
Before we even get to GTK; there are some issues with python wheels under msys2; check out: https://www.msys2.org/docs/python/ -- some wheels just can't be built under msys2 due to various incompatibilities. Not being able to replace such packages with 'pure' python equivalents could end up being a (very annoying) roadblock.
The roadblock that I recently ran into with my simple GTK4 app was unpredictable ids on d-bus interface exports. D-bus does work under msys2; though you have to start the user session manually; d-feet and gdbus also work; though, as always, there's a catch. On Linux I can automaticaly export 'action groups' that belong to
GtkApplicationWindowwidgets; & their 'object path's show up predictably under the application's path + / + the window's id. This makes it really convenient when you want to add basic 'remote controls' to your widgets. Under msys2, though, I can't figure out how to find those paths; which throws a monkey wrench, so to speak, in my 'remote control' implementation. Granted, d-bus is a linux-native technology; and expecting it to work w/o issues on windows is probably a bit too much.-- apart from those, I haven't run into any issues with GTK4 under msys2. The GTK3 packages available in their repos also work just fine.
I do agree with the others who recommend PySide, though. Their cross platform support appears to be more robust. Their documentation has been improving as well.
Tagging @cadekat@pawb.social as they've asked the same question.
Last night i was failing because of some VS components missing (iirc cl.exe, which was actually not missing at all).
Today, I've reinstalled Windows 10, to get a fresh start and follow wingtk's guide. First of all it failed as "choco install python" (as mentioned in the guide) installs python 3.12, which does not include distutils.
After that I've tried uninstalling python and installing python --version 3.10.11 with choco and got the same error as gvsbuild still defaulted to python 3.12, even after a few reboots.
Not knowing how to clean it up, decided on reinstalling Windows again, and installing python 3.10 only. Half an hour ago the build process failed for some (probably) network related issues ( ).
Currently I've installed a driver for the wireless card instead of using the built in one, and the build process has been stuck at "Opening https://download.gnome.org/sources/pango/1.51/pango-1.51.0.tar.xz ..." for at least the last half hour.
As for msys2, I haven't went that route yet, as I can't quite understand what it is and what it does. I can understand even less how to package a package installed with msys2 using either PyInstaller or nuitka, to have a (hopefully) single file executable, as I'm trying to distribute the app to my students, which are extremely non-technical.
I wish there was something like Wine for Windows.
Yeah I keep running into similar issues when trying to build pretty much anything on windows; for stuff that can't be 'nicely' configured & dependency-managed through an IDE, windows is pure pain.
It really sounds like PySide would fit your use case better. Check out this website for a great starting point: https://www.pythonguis.com/pyqt6/ -- the author also has an entire book on packaging PySide programs for cross-platform distribution.
As for installing Python itself; I think I'd stick with the plain installer from python.org, and afterwards, pip. In case of dependencies that are hard to get through PyPi, I think anaconda might be worth looking at as well: https://www.anaconda.com/download
msys2 provides a package manager, & several development toolchains; it's an easy way to get native (mingw) gcc & bash on windows; cross-platform programs rely on it heavily, because it saves them from all the 'visual studio' BS: https://www.msys2.org/docs/what-is-msys2/ -- I believe any implementation of GTK on windows requires a mingw toolchain.
