Yes, it's enabled in Guix, and my application works there, on the same target (on top of Debian), e.g. in the environment: --8<---------------cut here---------------start------------->8--- guix shell gtk+ python python-wxpython wxwidgets --8<---------------cut here---------------end--------------->8--- If I step out of the environment and rely on the Debian-provided (XTest-less) python3-wxgtk4.0/libwxgtk3.0-gtk3-0v5 packages instead, my application no longer works (pressing the virtual keyboard doesn't cause any text to appear in a text field, say). > Comments in that ticket suggest that XTest doesn't work on Wayland and > "Wayland is used by default in Debian 10 and newer" (10 is buster, the > current stable release right now which is about to become oldstable): > > https://wiki.debian.org/Wayland > > It looks like there isn't a Wayland-specific implementation in the > source and src/unix/uiactionx11.cpp uses X11-specific functions so > building with --with-xtest may not really solve your problem. > > Forcing use of X11 for the app may help, e.g.: > > GDK_BACKEND=x11 ./myapp My application runs strictly in a X11 environment on top of Raspberry Pi lite (which is based on Debian Bullseye). That lite image doesn't come with much and leaves the user choosing the components, similar to an Arch Linux system. I think even if for the default Wayland setup of Debian building wxWidgets with XTest won't provide much, at least it will be useful for users sticking to X11 and expecting https://docs.wxpython.org/wx.UIActionSimulator.html?highlight=uiactionsimulator#wx.UIActionSimulator to work with GTK+. At any rate, the size of having XTest in the distribution of libwxgtk3.0-gtk3-0v5 should be minimal, even if it's not useful to everyone. On Guix for example, the libxtst package and all its transitive (referenced) dependencies weighs only 86 MiB: --8<---------------cut here---------------start------------->8--- $ guix size libxtst store item total self /gnu/store/gsjczqir1wbz8p770zndrpw4rnppmxi3-glibc-2.35 40.6 38.8 47.5% /gnu/store/930nwsiysdvy2x5zv1sf6v7ym75z8ayk-gcc-11.3.0-lib 75.3 34.7 42.5% /gnu/store/qabydd2r26gcr9s26hzchip3a3h3zhg4-libxcb-1.15 78.5 3.0 3.7% /gnu/store/0hvkv5kvrk7ix29pfnbkyppbdxa7ki7n-libx11-1.8.1 81.2 2.8 3.4% /gnu/store/zzyywykw7kriln18rxqd82f0k5kidla7-bash-static-5.1.16 1.8 1.8 2.2% /gnu/store/z8kgahaarjpl0b1nzpqmzyrm4bbmnxw3-libxext-1.3.4 81.4 0.1 0.2% /gnu/store/xkzw5shd6bchzvhv9d6p08hsny749jdd-libxdmcp-1.1.3 75.4 0.1 0.2% /gnu/store/i7lls5jbad877g0fv7s87rlw0dgxp3wm-libxi-1.7.10 81.5 0.1 0.2% /gnu/store/ck5m2chijap9c8warmx4af7ppc0wixsx-libxtst-1.2.3 81.6 0.1 0.1% /gnu/store/yilf64y14qciml3kkj3506i3n2gmaawb-libxau-1.0.10 75.3 0.0 0.0% total: 81.6 MiB --8<---------------cut here---------------end--------------->8--- which is pretty small and probably composed of things already depended on by the Debian libwxgtk3.0-gtk3-0v5 package.

Ha! I think the small program attached demonstrates it well, if you'd like to try it.

It's been marked experimental for the last 14 years... :-). Thanks for your attention, and cheers! -- Maxim
