[Question] Make window type dock?

[alexmozaidze]

I was searching a way to make sdl window of type dock in X11 and found this issue, then I tried doing something like this:

const WM_WINDOW_TYPE_DOCK: &str = "_NET_WM_WINDOW_TYPE_DOCK";
const SDL_HINT: &str = "SDL_HINT_X11_WINDOW_TYPE";

println!("Setting dock hint...");
assert!(hint::set(SDL_HINT, WM_WINDOW_TYPE_DOCK));

println!("hint: {:?}", hint::get(SDL_HINT)); // Prints `Some("_NET_WM_WINDOW_TYPE_DOCK")`

but it didn't work. How can I tell WM that my sdl window is a dock?

Do you have a C example where it works as expected? This repo is explicitly for the rust bindings, if this isn't rust-related then I can't help you that much.

I don't, but the guy in the issue I linked said it worked. I'll try to get an example working with C and report back.

Getting latest SDL working is harder than I imagined, it might take me a while. I'm sure it's this commit that added the hint that specifies to X11 that it should treat SDL window as a dock. Could you update the SDL and the bindings so that feature is available? Now, I shall continue my journey of learning C and C compilers.

That explains it, the commit is only 4 days old. Unfortunately we only use the stable release in bundled and in the bindings, but you could always fork the project, update the submodule to your commit, and use the bundled feature then.

You also can use your own compiled SDL2 version with the proper cargo link parameters

@alexmozaidze The answer is in the commit you linked:

You should use "SDL_X11_WINDOW_TYPE", not "SDL_HINT_X11_WINDOW_TYPE"
